Member Enumeration Documentation

enum ConnectionTestFlag

Defines the connection test that can be done on animated attributes.

Enumerator
kTestDirtyPlug	Do not perform an additional test; the attribute is considered animated if part of the dirty plug list.
kTestHierarchy	Test whether the plug or any of its parents has a connection; if they don't the attribute is not considered animated.
kTestPlug	Test whether the plug has a connection; if it doesn't the attribute is not considered animated.
kLastConnectionTest	Last value, used for counting.
kTestDefaultValue	Value used by default for the tests.

void setUnsafeNode	(	MNodeCacheDisablingInfo &	disablingInfo,
		const MEvaluationNode &	node,
		const MString *	nodeCategory = `NULL`
	)

static

Helper to set the reason and mitigation for an unsafe node.

This method is a helper for derived clases implementing getCacheSetup().

It sets up a proper message and mitigation for an unsupported node.

Parameters

[out]	disablingInfo	The disabling info to set.
[in]	node	The evaluation node associated with the unsupported node.
[in]	nodeCategory	A group name to use in the reported messages, or a null pointer or an empty string to only use the node name.

void setUnsafeValue	(	MNodeCacheDisablingInfo &	disablingInfo,
		const MEvaluationNode &	node,
		const MObject &	attribute,
		const MString &	attributeValue,
		const MString &	supportedValue,
		const MString *	nodeCategory = `NULL`
	)

static

Helper to set the reason and mitigation for an unsafe value on a node's attribute.

This method is a helper for derived clases implementing getCacheSetup().

It sets up a proper message and mitigation for an unsupported value for an attribute on a node.

Parameters

[out]	disablingInfo	The disabling info to set.
[in]	node	The evaluation node associated with the unsupported node.
[in]	attribute	The unsafe attribute.
[in]	attributeValue	A string describing the current value of the attribute.
[in]	supportedValue	A string describing the supported value of the attribute.
[in]	nodeCategory	A group name to use in the reported messages, or a null pointer or an empty string to only use the node name.

bool testAnimatedAttribute	(	MNodeCacheDisablingInfo *	disablingInfo,
		MObjectArray &	monitoredAttributes,
		const MEvaluationNode &	node,
		const MPlug &	plug,
		ConnectionTestFlag	connectionTest = `kTestDefaultValue`,
		const MString *	nodeCategory = `NULL`,
		MStatus *	ReturnStatus = `NULL`
	)

static

Helper to set the reason and mitigation on a node with a conditionally supported attribute if it is animated.

This method is a helper for derived classes implementing getCacheSetup().

It is meant for attributes that can have a value that would prevent Cached Playback support. It checks that an attribute is animated, and therefore could take the wrong value. If the attribute is animated, it will populate the disabling info with the proper data. Otherwise, it will be added to the list of attributes to monitor.

An additional test can be performed to determine whether or not an attribute is animated. By default, the only test being performed is whether or not the attribute is part of the dirty plugs list. However, in a situation where the attribute is part of a compound structure, it might be useful to perform additional tests. For instance, if a sibling of the target attribute is animated, the whole compound, including the target attribute, will be considered animated as part of the dirty plugs list. A more thorough test can be performed to determine if the attribute, or any of its parents, is the destination of a connection. Depending on the connection setup, this might be enough to known that the attribute is not animated. The connectionTest parameter controls what extra test can be performed. By default, no extra test is performed and the animated status is determined from the dirty plugs list.

Note that if the attribute is animated, it will not be added to the list of attributes to monitor, since its value is expected to change over time without user manipulation.

Note that this method cannot be used on attributes in a complex hierarchy, such as multi attributes or children of multi attributes.

Parameters

[out]	disablingInfo	The disabling info to set, or nullptr to discard reason and mitigation messages.
[out]	monitoredAttributes	Attributes that influences if caching is supported.
[in]	node	Evaluation node associated with the node being tested.
[in]	plug	Plug to the attribute to be tested.
[in]	connectionTest	An additional test to perform to determine if the attribute is animated.
[in]	nodeCategory	A group name to use in the reported messages, or a null pointer or an empty string to only use the node name.
[out]	ReturnStatus	Status code.

Returns: True if the attribute is animated, false otherwise.

Status Codes:

MS::kSuccess Operation successful
MS::kInvalidParameter Attribute is null or part of a complex hierarchy

bool testBooleanAttribute	(	MNodeCacheDisablingInfo *	disablingInfo,
		MObjectArray &	monitoredAttributes,
		const MEvaluationNode &	node,
		const MObject &	attribute,
		bool	supportedValue,
		ConnectionTestFlag	connectionTest = `kTestDefaultValue`,
		const MString *	nodeCategory = `NULL`,
		MStatus *	ReturnStatus = `NULL`
	)

static

Helper to set the reason and mitigation on a node with a conditionally supported boolean attribute.

This method is a helper for derived classes implementing getCacheSetup().

It checks whether the attribute on a node is not animated and has the right supported value.

Note that this method calls testAnimatedAttribute() so it has the same requirements.

Note that this method works only for boolean attributes, and should not be called with a disabling info object that is already disabled.

Parameters

[out]	disablingInfo	The disabling info to set, or nullptr to discard reason and mitigation messages.
[out]	monitoredAttributes	Attributes that influences if caching is supported.
[in]	node	Evaluation node associated with the node being tested.
[in]	attribute	Attribute to be tested.
[in]	supportedValue	Value needed for Cached Playback to be supported.
[in]	connectionTest	An additional test to perform to determine if the attribute is animated.
[in]	nodeCategory	A group name to use in the reported messages, or a null pointer or an empty string to only use the node name.
[out]	ReturnStatus	Status code.

Returns: True if the attribute is animated or not the supported value, false otherwise.

Status Codes:

MS::kSuccess Operation successful
MS::kInvalidParameter Attribute is null or part of a complex hierarchy

bool testEnumAttribute	(	MNodeCacheDisablingInfo *	disablingInfo,
		MObjectArray &	monitoredAttributes,
		const MEvaluationNode &	node,
		const MObject &	attribute,
		const short	supportedValues[],
		int	supportedValuesCount,
		ConnectionTestFlag	connectionTest = `kTestDefaultValue`,
		const MString *	nodeCategory = `NULL`,
		MStatus *	ReturnStatus = `NULL`
	)
