Detailed Description

A node in a hierarchical collection of preference data.

This interface allows applications to store and retrieve user and system preference data. This data is stored persistently in an implementation-dependent backing store. Typical implementations include flat files, OS-specific registries, directory servers and SQL databases.

For each bundle, there is a separate tree of nodes for each user, and one for system preferences. The precise description of "user" and "system" will vary from one bundle to another. Typical information stored in the user preference tree might include font choice, and color choice for a bundle which interacts with the user via a servlet. Typical information stored in the system preference tree might include installation data, or things like high score information for a game program.

Nodes in a preference tree are named in a similar fashion to directories in a hierarchical file system. Every node in a preference tree has a node name (which is not necessarily unique), a unique absolute path name , and a path name relative to each ancestor including itself.

The root node has a node name of the empty QString object (""). Every other node has an arbitrary node name, specified at the time it is created. The only restrictions on this name are that it cannot be the empty string, and it cannot contain the slash character ('/').

The root node has an absolute path name of "/". Children of the root node have absolute path names of "/" + <node name> . All other nodes have absolute path names of <parent's absolute path name> + "/" + <node name> . Note that all absolute path names begin with the slash character.

A node n 's path name relative to its ancestor a is simply the string that must be appended to a 's absolute path name in order to form n 's absolute path name, with the initial slash character (if present) removed. Note that:

  • No relative path names begin with the slash character.
  • Every node's path name relative to itself is the empty string.
  • Every node's path name relative to its parent is its node name (except for the root node, which does not have a parent).
  • Every node's path name relative to the root is its absolute path name with the initial slash character removed.

Note finally that:

  • No path name contains multiple consecutive slash characters.
  • No path name with the exception of the root's absolute path name end in the slash character.
  • Any string that conforms to these two rules is a valid path name.

Each Preference node has zero or more properties associated with it, where a property consists of a name and a value. The bundle writer is free to choose any appropriate names for properties. Their values can be of type QString,long,int,bool, std::vector<char>,float, or double but they can always be accessed as if they were QString objects.

All node name and property name comparisons are case-sensitive.

All of the methods that modify preference data are permitted to operate asynchronously; they may return immediately, and changes will eventually propagate to the persistent backing store, with an implementation-dependent delay. The flush method may be used to synchronously force updates to the backing store.

Implementations must automatically attempt to flush to the backing store any pending updates for a bundle's preferences when the bundle is stopped or otherwise ungets the IPreferences Service.

The methods in this class may be invoked concurrently by multiple threads in a single Java Virtual Machine (JVM) without the need for external synchronization, and the results will be equivalent to some serial execution. If this class is used concurrently by multiple JVMs that store their preference data in the same backing store, the data store will not be corrupted, but no other guarantees are made concerning the consistency of the preference data.

Member Function Documentation

◆ AbsolutePath()

virtual QString berry::IPreferences::AbsolutePath ( ) const
pure virtual

Returns this node's absolute path name. Note that:

  • Root node - The path name of the root node is "/".
  • Slash at end - Path names other than that of the root node may not end in slash ('/').
  • Unusual names -"." and ".." have no special significance in path names.
  • Illegal names - The only illegal path names are those that contain multiple consecutive slashes, or that end in slash and are not the root.
Returns
this node's absolute path name.

◆ BlockSignals()

virtual void berry::IPreferences::BlockSignals ( bool  block)
pure virtual

Sets a flag to the parameter block which can be used to block berry messages in order to prevent callback functions to be called.

Parameters
blockboolean to set the flag

◆ ChildrenNames()

virtual QStringList berry::IPreferences::ChildrenNames ( ) const
pure virtual

Returns the names of the children of this node. (The returned array will be of size zero if this node has no children and not null!)

Returns
the names of the children of this node.
Exceptions
BackingStoreExceptionif this operation cannot be completed due to a failure in the backing store, or inability to communicate with it.
IllegalStateExceptionif this node (or an ancestor) has been removed with the Remove()method.

◆ Clear()

virtual void berry::IPreferences::Clear ( )
pure virtual

Removes all of the properties (key-value associations) in this node. This call has no effect on any descendants of this node.

Exceptions
BackingStoreExceptionif this operation cannot be completed due to a failure in the backing store, or inability to communicate with it.
IllegalStateExceptionif this node (or an ancestor) has been removed with the Remove()method.
See also
Remove(const QString&)

◆ Flush()

virtual void berry::IPreferences::Flush ( )
pure virtual

Forces any changes in the contents of this node and its descendants to the persistent store.

Once this method returns successfully, it is safe to assume that all changes made in the subtree rooted at this node prior to the method invocation have become permanent.

Implementations are free to flush changes into the persistent store at any time. They do not need to wait for this method to be called.

When a flush occurs on a newly created node, it is made persistent, as are any ancestors (and descendants) that have yet to be made persistent. Note however that any properties value changes in ancestors are not guaranteed to be made persistent.

Exceptions
BackingStoreExceptionif this operation cannot be completed due to a failure in the backing store, or inability to communicate with it.
IllegalStateExceptionif this node (or an ancestor) has been removed with the Remove()method.
See also
Sync()

bool  def 
) const
pure virtual

Returns the bool value represented by the QString object associated with the specified key in this node. Valid strings are "true", which represents true, and "false", which represents false. Case is ignored, so, for example, "TRUE" and "False" are also valid. This method is intended for use in conjunction with the PutBoolmethod.

Returns the specified default if there is no value associated with the key, the backing store is inaccessible, or if the associated value is something other than "true" or "false", ignoring case.

inlinestatic

Definition at line 121 of file berryIPreferences.h.

◆ Keys()

virtual QStringList berry::IPreferences::Keys ( ) const
pure virtual

Returns all of the keys that have an associated value in this node. (The returned array will be of size zero if this node has no preferences and not null!)

Returns
an array of the keys that have an associated value in this node.
Exceptions
BackingStoreExceptionif this operation cannot be completed due to a failure in the backing store, or inability to communicate with it.

◆ Name()

virtual QString berry::IPreferences::Name ( ) const
pure virtual

Returns this node's name, relative to its parent.

Returns
this node's name, relative to its parent.

◆ Node()

virtual IPreferences::Pointer berry::IPreferences::Node ( const QString &  pathName)
pure virtual

Returns a named IPreferences object (node), creating it and any of its ancestors if they do not already exist. Accepts a relative or absolute pathname. Absolute pathnames (which begin with '/') are interpreted relative to the root of this node. Relative pathnames (which begin with any character other than '/') are interpreted relative to this node itself. The empty string ("") is a valid relative pathname, referring to this node itself.

If the returned node did not exist prior to this call, this node and any ancestors that were created by this call are not guaranteed to become persistent until the flush method is called on the returned node (or one of its descendants).

Parameters
pathNamethe path name of the IPreferences object to return.
Returns
the specified IPreferences object.
Exceptions
IllegalArgumentExceptionif the path name is invalid.
IllegalStateExceptionif this node (or an ancestor) has been removed with the Remove()method.
NullPointerExceptionif path name is null.
See also
Flush()

◆ NodeExists()

virtual bool berry::IPreferences::NodeExists ( const QString &  pathName) const
pure virtual

Returns true if the named node exists. Accepts a relative or absolute pathname. Absolute pathnames (which begin with '/') are interpreted relative to the root of this node. Relative pathnames (which begin with any character other than '/') are interpreted relative to this node itself. The pathname "" is valid, and refers to this node itself.

If this node (or an ancestor) has already been removed with the Remove()method, it is legal to invoke this method, but only with the pathname ""; the invocation will return false. Thus, the idiom p.nodeExists("") may be used to test whether p has been removed.

Parameters
pathNamethe path name of the node whose existence is to be checked.
Returns
true if the specified node exists.
Exceptions
BackingStoreExceptionif this operation cannot be completed due to a failure in the backing store, or inability to communicate with it.
IllegalStateExceptionif this node (or an ancestor) has been removed with the Remove()method and pathname is not the empty string ("").
IllegalArgumentExceptionif the path name is invalid (i.e., it contains multiple consecutive slash characters, or ends with a slash character and is more than one character long).

◆ Parent()

virtual IPreferences::Pointer berry::IPreferences::Parent ( ) const
pure virtual

Returns the parent of this node, or null if this is the root.

Returns
the parent of this node.
Exceptions

◆ Put()

virtual void berry::IPreferences::Put ( const QString &  key,
const QString &  value

Parameters
keykey with which the specified value is to be associated.
valuevalue to be associated with the specified key.
Exceptions
NullPointerExceptionif key or value is null.

◆ PutBool()

virtual void berry::IPreferences::PutBool ( const QString &  key,
bool  value 
)
pure virtual

Associates a QString object representing the specified bool value with the specified key in this node. The associated string is "true" if the value is true, and "false" if it is false. This method is intended for use in conjunction with the GetBoolmethod.

Implementor's note: it is not necessary that the value be represented by a string in the backing store. If the backing store supports bool values, it is not unreasonable to use them. This implementation detail is not visible through the IPreferences API, which allows the value to be read as a bool (with getBool) or a QString (with get) type.

Parameters
keykey with which the string form of value is to be associated.
valuevalue whose string form is to be associated with key.

IllegalStateExceptionif this node (or an ancestor) has been removed with the Remove()method.

◆ RemoveNode()

virtual void berry::IPreferences::RemoveNode ( )
pure virtual

Removes this node and all of its descendants, invalidating any properties contained in the removed nodes. Once a node has been removed, attempting any method other than name(),absolutePath() or nodeExists("") on the corresponding IPreferences instance will fail with an IllegalStateException. (The methods defined on Object can still be invoked on a node after it has been removed; they will not throw IllegalStateException.)

The removal is not guaranteed to be persistent until the flush method is called on the parent of this node.
