in_ctxtICENode evaluation context.
in_nInputPortIDInput port identifier.
in_nInstanceIndexThe group instance of the port.
SICPPSDK_INLINE CDataArrayString ( ICENodeContext in_ctxt)

Destructor.


Member Function Documentation

SICPPSDK_INLINE CStatus CopyFrom ( ULONG  in_nInputPortID,
ULONG  in_nInstanceIndex = 0 
)

Copy the data from a given input port to this object buffer without allocating memory. This is typically used for passing data by reference from input to output ports, similar to what the built-in 'pass through' node is doing.

Parameters:
in_nInputPortIDInput port identifier.
in_nInstanceIndexThe group instance of the port.
Returns:
CStatus::OK Success
CStatus::InvalidArgument Fails if in_nInputPortID is not an input port identifier or in_nInstanceIndex is invalid.
CStatus::AccessDenied This array is not an output type or wasn't created properly.
Example:
        // Copy data from the ID_IN_STRING port to the current output port
        XSI::CDataArrayString outData( in_ctxt );
        outData.CopyFrom( ID_IN_STRING );
SICPPSDK_INLINE CStatus SetData ( ULONG  in_nIndex,
const CString in_str 
)

Sets the array at a specific position with the content of in_str.

Parameters:
in_nIndexArray index to store the string.
in_strCString object.
Returns:
Success/failure
See also:
CDataArrayString::Resize
SICPPSDK_INLINE CStatus GetData ( ULONG  in_nIndex,
CString out_str 
) const

Returns a CString object set with a copy of the string stored at a specific index.

Parameters:
in_nIndexArray index of the string to retrieve. The object is empty if no string is stored at this index.
Return values:
out_strCString object containing a copy of the string.
Returns:
Success/failure
SICPPSDK_INLINE CString operator[] ( ULONG  in_nIndex) const

Method returning a CString stored at in_nIndex. The CString object will contain a copy of the string.

Parameters:
in_nIndexIndex in the array. The index must be smaller than the number of elements in the array, otherwise the object returned is empty.
Returns:
CString object.
SICPPSDK_INLINE CStatus SetData ( ULONG  in_nIndex,
const TData *  in_pData,
ULONG  in_nCount 
)

Sets the array at a specific position with the content of in_pStr. This API will allocate emmory for in_nCount characters to store the user data.

Parameters:
in_nIndexArray index to store the user data.
in_pStrPointer to string data.
in_nCountNumber of characters to store.
Returns:
Success/failure
See also:
CDataArrayString::Resize
SICPPSDK_INLINE CStatus GetData ( ULONG  in_nIndex,
const TData **  out_ppStr,
ULONG &  out_nCount 
) const

Returns a pointer to the string stored at in_nIndex. The data is read-only and cannot be modified.

Note:
The memory allocated for the data returned by CDataArrayString::GetData is only available within the scope of this CDataArrayString instance. Make sure to make a copy of the data if you need to access it outside the scope of CDataArrayString.
Note:
The string returned in out_ppStr is not null-terminated, the caller must make sure to take the number of characters in account when manipulating the string.
Parameters:
in_nIndexArray index of the user data to retrieve. The size is 0 if no data is stored at this index.
Return values:
out_ppStrRead-only pointer to the string data.
out_nCountNumber of characters in the string.
Returns:
Success/failure
SICPPSDK_INLINE CStatus GetData ( ULONG  in_nIndex,
TData **  out_ppStr,
ULONG &  out_nCount 
) const

Returns a pointer to the string stored at in_nIndex. The data can be modified directly.

Note:
The memory allocated for the data returned by CDataArrayString::GetData is only available within the scope of this CDataArrayString instance. Make sure to make a copy of the data if you need to access it outside the scope of CDataArrayString.
Parameters:
in_nIndexArray index of the string to retrieve.
Return values:
out_ppStrPointer to the string.
out_nCountNumber of characters in the string.
Returns:
Success/failure
SICPPSDK_INLINE CDataArrayString::TData * Resize ( ULONG  in_nIndex,
ULONG  in_nCount 
)

Changes the size of the string buffer at a specific index to a specified size and returns a pointer to the allocated data.

Parameters:
in_nIndexArray index of the string buffer to resize.
in_nCountThe number of characters of the new array.
Returns:
Pointer to the allocated data.
SICPPSDK_INLINE ULONG GetCount ( void  ) const

Returns the number of characters in the array.

Returns:
Number of characters.
SICPPSDK_INLINE bool IsConstant ( ) const

Returns true if the array is constant or false otherwise. A constant array has only one value.

Returns:
True if constant, false otherwise.
