void GA_AttributeProxy::countMemory	(	UT_MemoryCounter &	counter,
		bool	inclusive
	)		const

Count memory usage using a UT_MemoryCounter in order to count shared memory correctly. If inclusive is true, the size of this object is counted, else only memory owned by this object is counted. If this is pointed to by the calling object, inclusive should be true. If this is contained in the calling object, inclusive should be false. (Its memory was already counted in the size of the calling object.)

NOTE: This treats GA_AttributeProxy as unshared, despite myReferenceCount, because the count should always be 1.

SYS_FORCE_INLINE GA_Attribute* GA_AttributeProxy::getAttribute ( )

inline

Obtains an actual attribute. May be NULL, if the attribute got deleted or was never actually found (or sussessfully created).

Definition at line 40 of file GA_AttributeProxy.h.

SYS_FORCE_INLINE const GA_Attribute* GA_AttributeProxy::getAttribute ( ) const

inline

Obtains an actual attribute. May be NULL, if the attribute got deleted or was never actually found (or sussessfully created).

bool GA_AttributeProxy::isLastReference

(

)

const

Checks if there is only one reference to this proxy (held by the caller)

SYS_FORCE_INLINE bool GA_AttributeProxy::isValid ( ) const

inline

Returns true if the proxy is still pointing to a valid attribute.
