Member Function Documentation

MAttributeIndex::MIndexType MAttributeIndex::type ( ) const

Returns the type of attribute index.

Valid index types are kInteger and kFloat.

Returns:: The index type

bool MAttributeIndex::hasRange ( ) const

Return true if a range was specified.

Note: false will be returned for an unbounded range which can be tested using the hasBound method.

Returns:: Boolean indicating whether the range exists or not.

bool MAttributeIndex::hasValidRange ( ) const

Return true if upper value is greater than lower value.

Returns:: Boolean indicating whether the range is valid or not.

bool MAttributeIndex::hasLowerBound ( ) const

Return true if if there is a lower bound specified.

Returns:: Boolean to indicate if there is a lower bound.

Examples:

apiMeshShape.cpp.

bool MAttributeIndex::hasUpperBound ( ) const

Return true if if there is an upper bound specified.

Returns:: Boolean to indicate if there is an upper bound.

Examples:

apiMeshShape.cpp.

MStatus MAttributeIndex::getLower ( int & value ) const

Return the lower bound for this object or false if 1) the type does not match the argument type or 2) there is no lower bound. (both of which can be tested for using other methods on this class).

Parameters:

[out] value lower bound value is returned through this parameter.

Returns:

MS::kSuccess the call was successful.
MS::kFailure method failed.

Examples:

apiMeshShape.cpp.

MStatus MAttributeIndex::getLower ( double & value ) const

Return the lower bound for this object or false if 1) the type does not match the argument type or 2) there is no lower bound. (both of which can be tested for using other methods on this class).

Parameters:

[out] value lower bound value is returned through this parameter.

Returns:

MS::kSuccess the call was successful.
MS::kFailure method failed.

MStatus MAttributeIndex::getUpper ( int & value ) const

Return the upper bound for this object or false if 1) the type does not match the argument type or 2) there is no upper bound. (both of which can be tested for using other methods on this class).

Parameters:

[out] value upper bound value is returned through this parameter.

Returns:

MS::kSuccess the call was successful.
MS::kFailure method failed.

Examples:

apiMeshShape.cpp.

MStatus MAttributeIndex::getUpper ( double & value ) const

Return the upper bound for this object or false if 1) the type does not match the argument type or 2) there is no upper bound. (both of which can be tested for using other methods on this class).

Parameters:

[out] value upper bound value is returned through this parameter.

Returns:

MS::kSuccess the call was successful.
MS::kFailure method failed.

bool MAttributeIndex::isBounded ( ) const

Returns true if this object is bounded.

Returns:

boolean indicating if the object is bounded.

MStatus MAttributeIndex::getValue ( int & value ) const

Return the current value of the index or false if 1) the type does not match the argument type or 2) the index is a range or 3) the index is unbounded.

Parameters:

[out] value value of the index is returned through this parameter.

Returns:

MS::kSuccess the call was successful.
MS::kFailure method failed.

MStatus MAttributeIndex::getValue ( double & value ) const

Return the current value of the index or false if 1) the type does not match the argument type or 2) the index is a range or 3) the index is unbounded.

Parameters:

[out] value value of the index is returned through this parameter.

Returns:

MS::kSuccess the call was successful.
MS::kFailure method failed.

MStatus MAttributeIndex::setType ( MAttributeIndex::MIndexType type )

Sets the type of attribute index.

Valid index types are kInteger and kFloat.

Parameters:

[in] type the index type to set

Returns:

MS::kSuccess the index type was set
MS::kFailure invalid index type specified

MStatus MAttributeIndex::setValue ( int value )

Sets the index value of this object.

Parameters:
