bnIsValidName
(name, allowWildcards=False)[source]¶ Check if a name is strictly well-formed.
Names can identify DG nodes, excluding the ones carrying any namespace or hierarchy information. They are made of character elements, that is alphanumeric characters, underscores, and wildcards.
Categories: explicit.
Parameters: - path (str) – Name to check.
- allowWildcards (bool) –
True
to consider the wildcards as valid characters.
Returns: True
if the name is strictly well-formed.Return type: bool

bnIsValidFullName
(name, allowWildcards=False, matchRelative=False)[source]¶ Check if a full name is strictly well-formed.
Full names can fully identify any DG node. They are composed by one or more name elements, each separated by the namespace delimiter
:
.Categories: explicit.
Parameters: - path (str) – Full name to check.
- allowWildcards (bool) –
True
to consider the wildcards as valid characters. - matchRelative (bool) –
True
to allow matching relatively to a parent namespace. That is, full names starting with the namespace delimiter:
are allowed.
Returns: True
if the full name is strictly well-formed.Return type: bool

bnIsValidPath
(path, allowWildcards=False)[source]¶ Check if a path is strictly well-formed.
Paths can identify DAG nodes, excluding the ones carrying any underworld information. They are composed by one or more full name elements, each starting with the hierarchy delimiter
|
.Categories: explicit.
Parameters: - path (str) – Path to check.
- allowWildcards (bool) –
True
to consider the wildcards as valid characters.
Returns: True
if the path is strictly well-formed.Return type: bool

bnIsValidFullPath
(path, allowWildcards=False, matchRelative=False)[source]¶ Check if a full path is strictly well-formed.
Full paths can fully identify any DAG node. They are composed by one or more path elements, each separated by the underworld delimiter
->
.Categories: explicit.
Parameters: - path (str) – Full path to check.
- allowWildcards (bool) –
True
to consider the wildcards as valid characters. - matchRelative (bool) –
True
to allow matching relatively to a parent path. That is, full paths starting with the underworld delimiter->
are allowed.
Returns: True
if the full path is strictly well-formed.Return type: bool

bnMakeMatchNameFunction
(pattern)[source]¶ Create a function to match names to a pattern.
Categories: explicit.
Parameters: pattern (str) – Name pattern to build. Wildcards are allowed. Returns: A function expecting a single parameter, that is the name to check the pattern against. The return value of this function is a value that evaluates to True
orFalse
in a boolean operation. The value passed to the parameter of this function must be a strictly well-formed name. No check is done to ensure the validity of the input but this can be done manually usingMGlobal.bnIsValidName()
.Return type: function Raises: ValueError
– The pattern is not well-formed.Examples
>>> import bana >>> bana.initialize() >>> from maya import OpenMaya >>> iterator = OpenMaya.MItDependencyNodes() >>> match = OpenMaya.MGlobal.bnMakeMatchNameFunction('*Shape*') >>> while not iterator.isDone(): ... obj = iterator.thisNode() ... name = OpenMaya.MFnDependencyNode(obj).name() ... if match(name): ... print(name) ... iterator.next()

bnMakeMatchFullNameFunction
(pattern, matchRelative=False)[source]¶ Create a function to match full names to a pattern.
Categories: explicit.
Parameters: - pattern (str) – Full name pattern to build. Wildcards are allowed.
- matchRelative (bool) –
True
to allow matching relatively to a parent namespace. That is, full names starting with the namespace delimiter:
are allowed.
Returns: A function expecting a single parameter, that is the full name to check the pattern against. The return value of this function is a value that evaluates to
True
orFalse
in a boolean operation. The value passed to the parameter of this function must be a strictly well-formed full name. No check is done to ensure the validity of the input but this can be done manually usingMGlobal.bnIsValidFullName()

bnMakeMatchPathFunction
(pattern)[source]¶ Create a function to match paths to a pattern.
Categories: explicit.
Parameters: pattern (str) – Path pattern to build. Wildcards are allowed. Returns: A function expecting a single parameter, that is the path to check the pattern against. The return value of this function is a value that evaluates to True
orFalse
in a boolean operation. The value passed to the parameter of this function must be a strictly well-formed path. No check is done to ensure the validity of the input but this can be done manually usingMGlobal.bnIsValidPath()
.Return type: function Raises: ValueError
– The pattern is not well-formed.Examples
