#include <MArgList.h>

Class Description

Create and retrieve argument lists.

This class is used to create and retrieve argument lists that can be passed to API class methods that require arglists.

Do not use MArgList to parse flags for a plug-in command as the flags will not work if the command is called from Python. Use MArgParser or MArgDatabase instead.

MS::kSuccess operation successful
MS::kFailure operation failed

MStatus get	(	unsigned int	index,
		MTime &	ret
	)		const

This method is not available in Python.

Get the value of the MTime argument at a given position in the arglist.

Python Notes

Use asTime() instead.

MStatus get	(	unsigned int &	index,
		MVector &	ret,
		unsigned int	numElements = `3`
	)		const

This method is not available in Python.

Get the value of the MVector argument at a given position in the arglist.

Python Notes

Use asVector() instead.

Parameters

[in,out]	index	index of the first argument to be used as an element of the vector. On success it will be updated to point to the last argument used to build the vector (i.e. incremented by numElements-1). On failure it will be updated to point to the argument where the failure occurred.
[out]	ret	the MVector value is returned in this argument.
[in]	numElements	dimension of the vector to be returned. This should not exceed 3, which is the maximum number of dimensions that an MVector can hold.

Returns

MS::kSuccess operation successful
MS::kFailure operation failed

MStatus get	(	unsigned int &	index,
		MPoint &	ret,
		unsigned int	numElements = `3`
	)		const

This method is not available in Python.

Get the value of the MPoint argument at a given position in the arglist.

Python Notes

Use asPoint() instead.

Parameters

[in,out]	index	index of the first argument to be used as an element of the point. On success it will be updated to point to the last argument used to build the point (i.e. incremented by numElements-1). On failure it will be updated to point to the argument where the failure occurred.
[out]	ret	the MPoint value is returned in this argument.
[in]	numElements	dimension of the point to be returned. This should not exceed 4, which is the maximum number of dimensions that an MPoint can hold.

Returns

MS::kSuccess operation successful
MS::kFailure operation failed

MStatus get	(	unsigned int &	index,
		MMatrix &	ret
	)		const

This method is not available in Python.

Get the value of the MMatrix argument at a given position in the arglist.

Python Notes

Use asMatrix() instead.

Parameters

[in,out]	index	index of the first argument to be used in building the matrix. On success it will be updated to point to the last argument used to build the matrix (i.e. it will be incremented by 15). On failure it will be updated to point to the argument where the failure occurred.
[out]	ret	the MMatrix value is returned in this argument.

Returns

MS::kSuccess operation successful
MS::kFailure operation failed

MStatus get	(	unsigned int &	index,
		MIntArray &	ret
	)		const

This method is not available in Python.

Get the value of the MIntArray argument at a given position in the arglist.

Python Notes

Use asIntArray() instead.

Parameters

[in,out]	index	index of the first argument to be used in building the array. That argument will be taken as an integer count of the number of array elements which follow it. On success the index will be updated to point to the argument for the last array element (i.e. incremented by the number of elements). On failure it will be updated to point to the argument where the failure occurred.
[out]	ret	the MIntArray value is returned in this argument.

Returns

MS::kSuccess operation successful
MS::kFailure operation failed

MStatus get	(	unsigned int &	index,
		MDoubleArray &	ret
	)		const

This method is not available in Python.

Get the value of the MDoubleArray argument at a given position in the arglist.

Python Notes

Use asDoubleArray() instead.

Parameters

[in,out]	index	index of the first argument to be used in building the array. That argument will be taken as an integer count of the number of array elements which follow it. On success the index will be updated to point to the argument for the last array element (i.e. incremented by the number of elements). On failure it will be updated to point to the argument where the failure occurred.
[out]	ret	the MDoubleArray value is returned in this argument.

Returns

MS::kSuccess operation successful
MS::kFailure operation failed

MStatus get	(	unsigned int &	index,
		MStringArray &	ret
	)		const

Parameters

[in,out]	index	index of the first argument to be used in building the array. That argument will be taken as an integer count of the number of array elements which follow it. On success the index will be updated to point to the argument for the last array element (i.e. incremented by the number of elements). On failure it will be updated to point to the argument where the failure occurred.
[out]	ret	the MStringArray value is returned in this argument.

Returns

MS::kSuccess operation successful
MS::kFailure operation failed
