Detailed Description

Most objects are derived from this class. This makes it possible to simplify the API, as object pointers can passed and not just void*.

Constructor & Destructor Documentation

Object()

jm::Object::Object ( )

noexcept

Constructor.

~Object()

virtual jm::Object::~Object ( )

virtualnoexcept

Destructor.

Member Function Documentation

autorelease()

Object * jm::Object::autorelease ( )

noexcept

Same function as release(), but releases the object with a delay if the reference counter is 0. AutoreleasePool::drain() must be called in the to release the object.

Returns

Reference to this object.

displayName()

virtual String jm::Object::displayName ( ) const

virtual

Returns the display name of the object intended to present to a user.

This method should be implemented by objects that want to present the name of the object to the user of an application. For example the diff-algorithm uses this or also the dwg objects.

Reimplemented in jm::LListElement, and jm::LinkedList.

equals()

virtual bool jm::Object::equals ( const Object *  other ) const

virtual

Comparison of objects.

Parameters

other

The object to compare with.

Reimplemented in jm::String.

highBit()

bool jm::Object::highBit ( ) const

noexcept

printDiffInfo()

virtual void jm::Object::printDiffInfo ( DiffOperation  operation, Object *  other  ) const

virtual

Output method for outputting the diff results for the diff algorithm.

Parameters

operation	The calculated diff operation.
other	The object to compare with.

referenceCount()

int32 jm::Object::referenceCount ( ) const

noexcept

Returns the value of the reference counter.

release()

void jm::Object::release ( )

noexcept

Decreases the reference counter and releases the object immediately when the reference counter becomes 0.

retain()

Object * jm::Object::retain ( )

noexcept

Increases the reference counter of this object by 1.

Note

An object is automatically released when the reference counter becomes 0.

Returns

Reference to this object.

setHighBit()

void jm::Object::setHighBit ( bool  status )

noexcept
