Member Function Documentation

static bool PDG_AttributeRef::attributeError ( UT_WorkBuffer &  buffer, PDG_AttributeError  error, const UT_StringHolder &  attrib_name, const PDG_AttributeOwner *  owner = nullptr  )

static

Writes an attribute error format message to the buffer, based on the supply error, attrib name and optional work item. Returns True if no error is detected, or false if an error occured.

static void PDG_AttributeRef::attributeModified ( const PDG_AttributeOwner *  owner, PDG_AttributeType  attrib_type, const UT_StringHolder &  attrib_name  )

static

Emits events when the attribute is modified.

PDG_AttributeError PDG_AttributeRef::error ( ) const

inline

Returns the error state of the handle.

Definition at line 55 of file PDG_AttributeRef.h.

bool PDG_AttributeRef::isValid ( ) const

inline

Returns true if the handle is valid.

Definition at line 51 of file PDG_AttributeRef.h.

const UT_StringHolder& PDG_AttributeRef::name ( void  ) const

inline

Returns the name of the attribute referenced by this attrib ref.

Definition at line 60 of file PDG_AttributeRef.h.

PDG_AttributeRef::operator bool ( ) const

inline

Returns true if the handle is valid.

Definition at line 47 of file PDG_AttributeRef.h.

const PDG_AttributeOwner* PDG_AttributeRef::owner ( ) const

inline

Returns the PDG_AttributeOwner that owns the underlying attribute.

Definition at line 64 of file PDG_AttributeRef.h.

bool PDG_AttributeRef::validate

(

UT_WorkBuffer &

buffer

)

const

Returns false and Writes an attribute error message into the buffer if an error exists, or returns trues and does not modify the buffer if no error has been recorded.

bool PDG_AttributeRef::validate	(	const PDG_Node *	node,
		bool	report_errors = true,
		bool	as_warning = false
	)		const

Same as above, except the attribute error is reported on the specified node instead of returned as a buffer, if an error has occured. The method still returns true if no error has occured, and false if one has.

The report_errors argument is provided as a convenience, to make it possible to parametrically skip error reporting
