Detailed Description

This is a table of all the external content for a given MPxNode.

External content is defined as any data that is not stored with the node and that is needed by the node to perform its work. It can be texture files, other scenes, audio files, etc.

Each node that references external content should report it through MPxNode::getExternalContent so that a complete list of external content can be saved with the scene in a way that makes it easy to inspect and edit offline.

Examples:: AbcImport/AlembicNode.cpp, AbcImport/AlembicNode.h, dx11Shader/dx11Shader.cpp, dx11Shader/dx11Shader.h, glslShader/GLSLShader.cpp, glslShader/GLSLShader.h, gpuCache/gpuCacheShapeNode.cpp, gpuCache/gpuCacheShapeNode.h, sceneAssembly/adskRepresentations.cpp, sceneAssembly/adskRepresentations.h, sceneAssembly/assemblyDefinition.cpp, sceneAssembly/assemblyDefinition.h, sceneAssembly/assemblyReference.cpp, and sceneAssembly/assemblyReference.h.

MStatus addResolvedEntry	(	const MString &	key,
		const MString &	unresolvedLocation,
		const MString &	resolvedLocation,
		const MStringArray &	roles
	)

This method is obsolete.

Add an entry in the table.

[as of Maya 2019]

Deprecated:: Context (owner Node full name) must be provided to the Maya resolver. Use the one with the contextNodeFullName input param.

Parameters

[in]	key	An arbitrary string defined by the caller. This will typically be an attribute name for situations where the content location is stored verbatim in a plug's value.
[in]	unresolvedLocation	Path as stored in the node (i.e. without any token replacement performed).
[in]	resolvedLocation	Full path to the content if it exists at the time of creation of this object.
[in]	roles	An enumeration of all roles this content plays in the context of the node. The actual strings are not rigidly defined as of this writing. This is mostly for offline browsing of the content info: to assist in sorting content by role. A better content type system may be introduced later on to formalize this.

Returns: Return status.

Status Codes:

MS::kSuccess The method successfully added the entry.
MS::kFailure The method failed to add the entry.

Examples:: sceneAssembly/assemblyDefinition.cpp.

MStatus addResolvedEntry	(	const MString &	key,
		const MString &	unresolvedLocation,
		const MString &	resolvedLocation,
		const MString &	contextNodeFullName,
		const MStringArray &	roles
	)

Add an entry in the table.

Parameters

[in]	key	An arbitrary string defined by the caller. This will typically be an attribute name for situations where the content location is stored verbatim in a plug's value.
[in]	unresolvedLocation	Path as stored in the node (i.e. without any token replacement performed).
[in]	resolvedLocation	Full path to the content if it exists at the time of creation of this object.
[in]	contextNodeFullName	The fullname of the URI owner (node) if it applies, an empty string otherwise.
[in]	roles	An enumeration of all roles this content plays in the context of the node. The actual strings are not rigidly defined as of this writing. This is mostly for offline browsing of the content info: to assist in sorting content by role. A better content type system may be introduced later on to formalize this.

Returns: Return status.

Status Codes:

MS::kSuccess The method successfully added the entry.
MS::kFailure The method failed to add the entry.

MStatus addUnresolvedEntry	(	const MString &	key,
		const MString &	unresolvedLocation,
		const MStringArray &	roles = `MStringArray()`
	)

This method is obsolete.

Add an entry in the table.

[from before Maya 2016]

Deprecated:: Context (owner Node full name) must be provided to the Maya resolver. Use the one with the contextNodeFullName input param.

The resolved location will be inferred from the application's built-in file resolving for the specified file type. This will automatically add entries into the roles vector that correspond to the search rules for this file type.

Parameters

[in]	key	See documentation for MExternalContentInfoTable::addResolvedEntry.
[in]	unresolvedLocation	See documentation for MExternalContentInfoTable::addResolvedEntry.
[in]	roles	See documentation for MExternalContentInfoTable::addResolvedEntry.

Returns: Return status.

Status Codes:

MS::kSuccess The method successfully added the entry.
MS::kFailure The method failed to add the entry.

Examples:: sceneAssembly/adskRepresentations.cpp, and sceneAssembly/assemblyReference.cpp.

MStatus addUnresolvedEntry	(	const MString &	key,
		const MString &	unresolvedLocation,
		const MString &	contextNodeFullName,
		const MStringArray &	roles = `MStringArray()`
	)

Add an entry in the table.

The resolved location will be inferred from the application's built-in file resolving for the specified file type. This will automatically add entries into the roles vector that correspond to the search rules for this file type.

Parameters

[in]	key	See documentation for MExternalContentInfoTable::addResolvedEntry.
[in]	unresolvedLocation	See documentation for MExternalContentInfoTable::addResolvedEntry.
[in]	contextNodeFullName	See documentation for MExternalContentInfoTable::addResolvedEntry.
[in]	roles	See documentation for MExternalContentInfoTable::addResolvedEntry.

Returns: Return status.

Status Codes:

MS::kSuccess The method successfully added the entry.
MS::kFailure The method failed to add the entry.
