Detailed Description

Light weight base class for most BlueBerry classes.

Object is copied from itk::LightObject and is the highest level base class for most BlueBerry objects. It implements reference counting and the API for object printing.

References berry::DebugUtil::RegisterObject().

Referenced by berry::EvaluationResult::operator!=().

◆ ~Object()

berry::Object::~Object ( )

warn user if reference counting is on and the object is being referenced by another object.

notifies the registered functions that the object is being destroyed

Member Function Documentation

◆ AddDestroyListener()

void berry::Object::AddDestroyListener ( const MessageAbstractDelegate<> &  delegate) const

Definition at line 153 of file berryObject.h.

◆ Delete()

void berry::Object::Delete ( )

Delete an BlueBerry object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

Definition at line 31 of file berryObject.cpp.

References UnRegister().

◆ GetClassName()

◆ GetReferenceCount()

int berry::Object::GetReferenceCount ( ) const

Gets the reference count on this object.

Definition at line 144 of file berryObject.h.

◆ GetSuperclasses()

QList< Reflection::TypeInfo > berry::Object::GetSuperclasses ( ) const

Reimplemented in berry::ObjectTypeInfo.

References GetStaticSuperclasses().

◆ GetTypeInfo()

Reflection::TypeInfo berry::Object::GetTypeInfo ( ) const

Reimplemented in berry::ObjectTypeInfo.

Definition at line 81 of file berryObject.cpp.

References GetStaticTypeInfo().

◆ HashCode()

uint berry::Object::HashCode ( ) const

Returns a hash code value for the object.

Reimplemented in berry::Saveable, berry::ParameterizedCommand, berry::Expression, berry::HandleObject, and berry::QActionContributionItem.

Definition at line 111 of file berryObject.cpp.

References qHash().

Referenced by qHash().

◆ operator<()

bool berry::Object::operator< ( const Object o) const

Override this method to implement a specific "less than" operator for associative STL containers.

Reimplemented in berry::Command, berry::Saveable, berry::ParameterizedCommand, and berry::ParameterType.

Definition at line 116 of file berryObject.cpp.

◆ operator==()

◆ Print()

QDebug berry::Object::Print ( QDebug  os,
Indent  Indent = 0 
) const

Cause the object to print itself out. This is usually used to provide detailed information about the object's state. It just calls the header/self/trailer virtual print methods, which can be overriden by subclasses.

Definition at line 96 of file berryObject.cpp.

References berry::Indent::GetNextIndent(), PrintHeader(), PrintSelf(), and PrintTrailer().

Referenced by operator<<(), and ToString().

◆ PrintHeader()

QDebug berry::Object::PrintHeader ( QDebug  os,
Indent  Indent 
) const

Define a default print header for all objects.

Definition at line 212 of file berryObject.cpp.

References GetClassName().

Referenced by Print().

◆ PrintSelf()

QDebug berry::Object::PrintSelf ( QDebug  os,
Indent  indent 
) const

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

◆ PrintTrailer()

QDebug berry::Object::PrintTrailer ( QDebug  os,
Indent  indent 
) const

Define a default print trailer for all objects.

void berry::Object::Register ( ) const

◆ RemoveDestroyListener()

void berry::Object::RemoveDestroyListener ( const MessageAbstractDelegate<> &  delegate) const

Definition at line 155 of file berryObject.h.

References mitk::operator==().

◆ SetReferenceCount()

void berry::Object::SetReferenceCount ( int  ref)

Sets the reference count on this object. This is a dangerous method, use it with care.

Definition at line 134 of file berryObject.cpp.

References m_ReferenceCount, and m_ReferenceCountLock.

◆ ToString()

QString berry::Object::ToString ( ) const

◆ UnRegister()

void berry::Object::UnRegister ( bool  del = true) const

Decrease the reference count (release by another object). Set del to false if you do not want the object to be deleted if the reference count is zero (use with care!)

Definition at line 126 of file berryObject.cpp.
