CICEAttributeDataArray2D< T > Class Template Reference

Detailed Description

template<class T>
class XSI::CICEAttributeDataArray2D< T >

This template class encapsulates ICEAttribute data as a 2D array. CICEAttributeDataArray2D objects are read-only and can be filled with the methods supplied with the ICEAttribute class. CICEAttributeDataArray2D is zero-based and can be one of the following types:

All types are associated to specific ICEAttribute 2D types. Therefore, you need to declare the right array object type that matches the ICEAttribute data type you want to access. Otherwise a runtime error will occur and the returned array will be empty.

CStatus GetSubArray ( ULONG  in_index,
CICEAttributeDataArray< T > &  out_dataArray 
) const [inline]

Accessor to the encapsulated array. This operator is called when reading the data so the return value is read-only.

Parameters:
in_index Index in the array. The index must be smaller than the number of elements in the array, otherwise the result is unpredictable.
out_dataArray A read-only reference to a CICEAttributeDataArray<T> object at a specific index.
Returns:
CStatus::OK Success
CStatus::InvalidArgument If in_index or out_dataArray is invalid.
CStatus ResizeSubArray ( ULONG  in_index,
ULONG  in_ulSize,
CICEAttributeDataArray< T > &  out_dataArray 
) [inline]

Changes the size of the sub-array at a given index and returns a new array pointing to the resized sub-array. This is only supported for writable attributes and not available for built-in attributes.

Parameters:
in_index Index in the array. The index must be smaller than the number of elements in the array, otherwise the result is unpredictable.
out_dataArray A reference to a CICEAttributeDataArray<T> object at a specific index.
in_ulSize The size of the array.
Returns:
CStatus::OK Success
CStatus::InvalidArgument If in_index or out_dataArray is invalid.
Since:
11.0 (2013)
