Detailed Description

template<typename Attribute>
class PDG_RWAttributeRef< Attribute >

Read/write attribute ref that permits modifications of holder flags as well as non-const access to the underlying data. Accessing the attribute using either the named accessor or the -> overload will result in a deep copy + ownership being taken, if the data is not already owned by the holder.

Constructor & Destructor Documentation

template<typename Attribute>

PDG_RWAttributeRef< Attribute >::PDG_RWAttributeRef	(	const UT_StringHolder &	name,
		const PDG_AttributeOwner *	owner
	)

inline

Constructs an uninitialized RW ref.

Definition at line 772 of file PDG_AttributeRef.h.

template<typename Attribute>

PDG_RWAttributeRef< Attribute >::PDG_RWAttributeRef	(	PDG_AttributeHolder *	holder,
		const UT_StringHolder &	name,
		const PDG_AttributeOwner *	owner,
		PDG_AttributeError	error = `PDG_AttributeError::eNone`
	)

inline

Constructs a ref that can modify attribute data. We store the work item so we can emit events.

Definition at line 781 of file PDG_AttributeRef.h.

template<typename Attribute>

PDG_RWAttributeRef< Attribute >::PDG_RWAttributeRef ( const Self & other )

inline

Explicitly defined copy constructor, since we don't want to copy the myModified flag from the source reference. Doing so would mean that we'd potentially by emitting an extra data change event on destruction.

Definition at line 794 of file PDG_AttributeRef.h.

template<typename Attribute>

PDG_RWAttributeRef< Attribute >::PDG_RWAttributeRef ( Self && other )

inline

Explicitly defined move constructor, since a copy constructor has been defined. When moving a ref we do want to preserve the myModified flag, unlike in the copy constructor.

Definition at line 803 of file PDG_AttributeRef.h.

template<typename Attribute>

PDG_RWAttributeRef< Attribute >::~PDG_RWAttributeRef ( )

inline

Emits data changed events if this attribute ref recorded a modification.

Definition at line 811 of file PDG_AttributeRef.h.

Member Function Documentation

template<typename Attribute>

Attribute* PDG_RWAttributeRef< Attribute >::attribute ( )

inline

Returns a non-const pointer to the underlying attribute instance. This induces a copy if the attribute is not already owned, and counts as a modification for the purpose of event handling.

Definition at line 866 of file PDG_AttributeRef.h.

template<typename Attribute>

void PDG_RWAttributeRef< Attribute >::clearEvents ( )

inline

Clears any pending events.

Definition at line 858 of file PDG_AttributeRef.h.

template<typename Attribute>

void PDG_RWAttributeRef< Attribute >::emitEvents ( )

inline

Emits pending events from the ref.

Definition at line 849 of file PDG_AttributeRef.h.

template<typename Attribute>

Attribute* PDG_RWAttributeRef< Attribute >::operator-> ( )

inline

Returns a non-const pointer to the underlying attribute instance.

Definition at line 876 of file PDG_AttributeRef.h.

template<typename Attribute>

Self& PDG_RWAttributeRef< Attribute >::operator= ( const Self & other )

inline

Explicitly defined copy assignment operator, since the copy constructor is defined.

Definition at line 818 of file PDG_AttributeRef.h.

template<typename Attribute>

Self& PDG_RWAttributeRef< Attribute >::operator= ( Self && other )

inline

Explicitly defined move assignment operator, since the move constructor is defined.

Definition at line 833 of file PDG_AttributeRef.h.

template<typename Attribute>

PDG_AttributeError PDG_RWAttributeRef< Attribute >::setFlag	(	PDG_AttributeFlag	flag,
		bool	set,
		bool &	changed
	)

inline

Sets the specific flag on or off, based on the set arugment, an returns whether or not the flag was changed.

Definition at line 884 of file PDG_AttributeRef.h.

template<typename Attribute>

PDG_AttributeError PDG_RWAttributeRef< Attribute >::setFlag	(	PDG_AttributeFlag	flag,
		bool	set
	)

inline

Sets the specific flag on or off.

Definition at line 900 of file PDG_AttributeRef.h.

template<typename Attribute>

PDG_AttributeError PDG_RWAttributeRef< Attribute >::setFlags	(	uint16	flags,
		bool &	changed
	)

inline

Directly sets the flag bits to the specified flags.

Definition at line 908 of file PDG_AttributeRef.h.

template<typename Attribute>

PDG_AttributeError PDG_RWAttributeRef< Attribute >::setFlags ( uint16 flags )

inline

Sets all flags.

Definition at line 922 of file PDG_AttributeRef.h.

template<typename Attribute>

void PDG_RWAttributeRef< Attribute >::truncate ( int length )

inline

Truncates the array stored in the attribute.

Definition at line 929 of file PDG_AttributeRef.h.
