Detailed Description

Abstract base class for Attribute interface.

This base class defines an interface for factory objects that runtimes implement to handle the various supported attribute types (such as bool, int, float, etc).

Constructor & Destructor Documentation

◆ Attribute() [1/3]

Ufe::Attribute::Attribute ( const SceneItem::Ptr & )

Constructor.

◆ ~Attribute()

virtual Ufe::Attribute::~Attribute ( )

virtual

◆ Attribute() [2/3]

Ufe::Attribute::Attribute ( const Attribute & )

delete

No copy or move constructor/assignment.

◆ Attribute() [3/3]

Ufe::Attribute::Attribute ( Attribute && )

delete

No copy or move constructor/assignment.

Member Function Documentation

◆ clearMetadata()

virtual bool Ufe::Attribute::clearMetadata ( const std::string & key )

pure virtual

Clear the metadata key's value.

Parameters

[in] key The metadata key to clear.

Returns: True if the metadata was cleared successfully, otherwise false.

◆ documentation()

virtual std::string Ufe::Attribute::documentation ( ) const

pure virtual

Returns: The attributes documentation string.

◆ getMetadata()

virtual Value Ufe::Attribute::getMetadata ( const std::string & key ) const

pure virtual

Get the value of the metadata named key.

Parameters

[in] key The metadata key to query.

Returns: The value of the metadata key. If the key does not exist an empty Value is returned.

◆ hasMetadata()

virtual bool Ufe::Attribute::hasMetadata ( const std::string & key ) const

pure virtual

Returns true if metadata key has a non-empty value.

◆ hasValue()

virtual bool Ufe::Attribute::hasValue ( ) const

pure virtual

Returns: true if this attribute has a value.

◆ name()

virtual std::string Ufe::Attribute::name ( ) const

pure virtual

Returns: The attributes name.

◆ operator!=()

bool Ufe::Attribute::operator!= ( const Attribute & rhs ) const

Unfortunately no compiler-generated default equality operators. Attribute names are only unique within a SceneItem, so an Attribute is equal if both the SceneItem (which matches path) and name match.

◆ operator=() [1/2]

Attribute& Ufe::Attribute::operator= ( const Attribute & )

delete

No copy or move constructor/assignment.

◆ operator=() [2/2]

Attribute& Ufe::Attribute::operator= ( Attribute && )

delete

No copy or move constructor/assignment.

◆ operator==()

bool Ufe::Attribute::operator== ( const Attribute & rhs ) const

Unfortunately no compiler-generated default equality operators. Attribute names are only unique within a SceneItem, so an Attribute is equal if both the SceneItem (which matches path) and name match.

◆ sceneItem()

SceneItem::Ptr Ufe::Attribute::sceneItem ( ) const

Returns: The object's SceneItem.

◆ setMetadata()

virtual bool Ufe::Attribute::setMetadata	(	const std::string &	key,
		const Value &	value
	)

pure virtual

Set the metadata key's value to value.

Parameters

[in]	key	The metadata key to set.
[in]	value	The value to set.

Returns: True if the metadata was set successfully, otherwise false.

◆ setMetadataCmd()

virtual UndoableCommand::Ptr Ufe::Attribute::setMetadataCmd	(	const std::string &	key,
		const Value &	value
	)

virtual

Return a command for undo / redo that sets the metadata key's value to value. The returned command is not executed; it is up to the caller to call execute().

◆ string()

virtual std::string Ufe::Attribute::string ( ) const

pure virtual

Returns: The string representation of the attribute value.

◆ type()

virtual Type Ufe::Attribute::type ( ) const

pure virtual

Returns: The attributes type.

Implemented in Ufe::TypedAttribute< T >, Ufe::AttributeEnumString, Ufe::AttributeFilename, and Ufe::AttributeGeneric.
