Import

from weSkel.src.core.node.dg.compose_matrix.lib import ComposeMatrix

Run in Maya or an initialized mayapy process. Import om only if your script uses OpenMaya types.

Inheritance and scope

Item	Value
Classe	ComposeMatrix
Module	weSkel.src.core.node.dg.compose_matrix.lib
Maya type	composeMatrix
Direct parent	DGNode
Inventory	Members defined or overridden here; inherited members are grouped by parent in each section.

Constructor

Signature : ComposeMatrix(node) → ComposeMatrix.

Parameter	Accepted type	Default
node	Union[str, om.MObject, om.MObjectHandle, om.MFnDependencyNode]	Required

Wraps an existing node or stages a wrapper for an absent name; does not create the node. Call create() separately. An incompatible object or type can raise TypeError. Shared identity can return an already registered compatible wrapper.

Properties

Python properties defined or overridden here. R: read-only; R/W: a setter exists, subject to the member notes. om.* types belong to maya.api.OpenMaya.

No new Python property; see inherited members and specs below.

Properties inherited from Node10

Property	Return type	Access	Description
mobject	om.MObject	R/W	Live Maya object, or a null object.
mobject_handle	om.MObjectHandle	R/W	Handle associated with the node.
api_type	int | None	R	Maya API type identifier.
api_type_str	str	R	API type name, for example "kTime".

is_valid_handle	bool	R	Validity of the stored handle.
is_dag_node	bool	R	Compatibility with om.MFn.kDagNode.
hash_code	int	R	Maya handle hash.

Spec properties

Defaults and flags below are spec declarations, not guaranteed live values. A descriptor can return a proxy: .value reads its value; .plug accesses the Plug. Proxy names describe results, not private classes to import. Observed types come from a test fixture; disconnected geometry inputs may notably return None.

For writes where failure must be checked, use the Plug explicitly and verify live state. Descriptor setters do not propagate every native failure.

Specs inherited from DGNode6

Property	Maya plug	Returns	Description
message	message	None	Node message plug; used for connections, with no numeric value.

Methods

No additional public method; inherited methods remain available.

Methods inherited from DGNode7

Method	Returns	Description
create	None	Creates a missing node; does nothing if it already exists.
delete	None	Disconnects live connections, detaches the wrapper and deletes the node.
snapshot	DGSnapshot	Captures and stores an identity and spec-driven SVD dictionary.
snapshot_svd	SVDSnapshot	Captures Source / Value / Destinations for the requested list.
svd	SVDView	Returns a read-only live view of source, value and destinations; it is not a frozen capture.
finalize	None	Applies all sources, then undriven values, then destinations; enabled FSET dispatch follows.
clear_attr_cache	None	Clears this instance attribute cache; does not delete nodes or clear the global wrapper registry.

Methods inherited from Node2

Method	Returns	Description
has_fn(fn_type)	bool	Test compatibility with a Maya function set.
clear_node_registry()	None	Detach registered wrappers and clear their shared registry.

Class attributes

Attribute	Value / composition
NODE_TYPE	'composeMatrix'
SPEC_LAYERS	get_dg_specs_all, get_compose_matrix_specs_all

NODE_REGISTRY and other class attributes not overridden here remain inherited. Exported Snapshot types describe dictionaries; use node.snapshot() to capture state.

Behavior at a glance

Point	Behavior
Identity	A node recreated under the same name is a new Maya object.
Creation and geometry	The constructor creates nothing; call create() before live operations.
Capture	Snapshots can contain Maya objects; do not assume JSON-ready data or complete geometry reconstruction.

Usage examples

Self-contained Maya Python Script Editor example. In mayapy, initialize maya.standalone before this block. The demonstration creates its own nodes and removes them in finally.

from uuid import uuid4
import maya.api.OpenMaya as om
from weSkel.src.core.node.dg.compose_matrix.lib import ComposeMatrix

node = ComposeMatrix("api_compose_matrix_" + uuid4().hex[:8])
try:
    node.create()
    node.input_translate = (1.0, 2.0, 3.0)
    result = om.MTransformationMatrix(node.output_matrix.value)
    assert result.translation(om.MSpace.kTransform).isEquivalent(om.MVector(1.0, 2.0, 3.0), 1e-6)
    print("ComposeMatrix: native evaluation OK")
finally:
    node.delete(snapshot=False)

Expected result : ComposeMatrix: native evaluation OK.

SDK checkpoint 87c3486. Member inventory checked against loaded classes in Maya 2025.3 and 2026.3; reads and compatibility are specified in the member cards. Example run in both versions, including explicitly documented expected failures. The example does not cover every method. Listed limitations remain in source; these checks do not validate the compiled package.
