Detailed Description

Provides information about the type of a command parameter. Clients can use a parameter type to check if an object matches the type of the parameter with IsCompatible(Object::Pointer) and can get an IParameterValueConverter to convert between objects matching the parameter type and strings that encode the object's identity.

A command parameter is not required to declare a type. To determine if a given parameter has a type, check if an IParameter implements ITypedParameter and if so, use ITypedParameter#GetParameterType() like this:

                  IParameter::Pointer parameter = // ... get IParameter from Command
                  if (ITypedParameter::Pointer typedParameter = parameter.Cast<ITypedParameter>())
                    ParameterType::Pointer type = typedParameter->GetParameterType();
                    if (type) {
                      // this parameter has a ParameterType

Constructor & Destructor Documentation

◆ ParameterType()

berry::ParameterType::ParameterType ( const QString &  id)

Constructs a new instance based on the given identifier. When a parameter type is first constructed, it is undefined. Parameter types should only be constructed by the CommandManager to ensure that the identifier remains unique.

idThe identifier for this type. This value must not be null, and must be unique amongst all parameter types.

Member Function Documentation

◆ AddListener()

void berry::ParameterType::AddListener ( IParameterTypeListener listener)

Adds a listener to this parameter type that will be notified when its state changes.

listenerThe listener to be added; must not be null.

◆ berryObjectMacro()

berry::ParameterType::berryObjectMacro ( ParameterType  )

◆ Define()

void berry::ParameterType::Define ( const QString &  type,
const QSharedPointer< IParameterValueConverter > &  parameterTypeConverter 

Defines this parameter type, setting the defined property to true.

Notification is sent to all listeners that something has changed.

typea string identifying the object type for this parameter type; null is interpreted as "QObject"
parameterTypeConverteran AbstractParameterValueConverter to perform string/object conversions for parameter values; may be null

◆ GetValueConverter()

IParameterValueConverter* berry::ParameterType::GetValueConverter ( ) const

Returns the value converter associated with this parameter, if any.

The parameter value converter, or null if there is no value converter for this parameter.
NotDefinedExceptionif the parameter type is not currently defined

◆ IsCompatible()

bool berry::ParameterType::IsCompatible ( const QObject *const  value) const

Returns whether the provided value is compatible with this parameter type. An object is compatible with a parameter type if the object is an instance of the class defined as the parameter's type class.

valuean object to check for compatibility with this parameter type; may be null.
true if the value is compatible with this type, false otherwise
NotDefinedExceptionif the parameter type is not currently defined

◆ operator<()

bool berry::ParameterType::operator< ( const Object object) const

Compares this parameter type with another object by comparing each of the non-transient attributes.

objectThe object with which to compare; must be an instance of ParameterType.
A negative integer, zero or a positive integer, if the object is greater than, equal to or less than this parameter type.

Reimplemented from berry::Object.

◆ RemoveListener()

void berry::ParameterType::RemoveListener ( IParameterTypeListener listener)

Unregisters listener for changes to properties of this parameter type.

listenerthe instance to unregister. Must not be null. If an attempt is made to unregister an instance which is not already registered with this instance, no operation is performed.

◆ ToString()

QString berry::ParameterType::ToString ( ) const

The string representation of this parameter type. For debugging purposes only. This string should not be shown to an end user.

The string representation; never null.

Reimplemented from berry::Object.

◆ Undefine()

void berry::ParameterType::Undefine ( )

Makes this parameter type become undefined. Notification is sent to all listeners.

Implements berry::HandleObject.
