- The Dataspace class serves as a very simple container for
- all kinds of data. You can add data items and reference them
- later through an ID. Furthermore, Dataspace class features
- methods to import/export a complete Dataspace from/to an IFF
- file handle.
-
- MUI uses subclasses of dataspace class to handle all its
- configuration data and thats probably the main purpose of a
- dataspace.
- Dataspace.mui/MUIA_Dataspace_Pool
-
- NAME
- MUIA_Dataspace_Pool -- (V11) [I..], APTR
-
- FUNCTION
- If you specify a memory pool from exec.library/CreatePool()
- here, the dataspace object will use this pool for all its
- entries.
-
- If you omit this tag or pass NULL, the dataspace object
- will create its own memory pool instead.
-
- SEE ALSO
- MUIM_Dataspace_Add, exec.library/CreatePool
- Dataspace.mui/MUIM_Dataspace_Add
-
- NAME
- MUIM_Dataspace_Add (V11)
-
- SYNOPSIS
- DoMethod(obj,MUIM_Dataspace_Add,APTR data, LONG len, ULONG id);
-
- FUNCTION
- This method adds a new entry to the dataspace. If an entry
- with the same ID already exists, it will be replaced with
- the new entry.
-
- INPUTS
- data - pointer to a data
- len - length of data
- id - reference id
-
- RESULT
- Returns NULL on failure (probably because of a memory
- shortage) or some non NULL value on success.

-
- NAME
- MUIM_Dataspace_Clear (V11)
-
- SYNOPSIS
- DoMethod(obj,MUIM_Dataspace_Clear,);
-
- FUNCTION
- This method clears all the contents of a dataspace. Depending
- on the state of the memory pool that the dataspace object uses,
- this may or may not result in more free memory.
-
- INPUTS
- none
-
- RESULT
- All entries will be removed from the dataspace.
- The return value of this method is currently undefined.

- SYNOPSIS

-
- NAME
- MUIM_Dataspace_Merge (V11)
-
- SYNOPSIS
- DoMethod(obj,MUIM_Dataspace_Merge,Object *dataspace);
-
- FUNCTION
- This method adds all the contents of the merge dataspace
- specified as parameter to the objects dataspace.
- As with MUIM_Dataspace_Add, entries with equal IDs
- will be replaced.
-
- INPUTS
- dataspace - dataspace objects whichs contents should
- be merged.
-
- RESULT
- Returns the number of entries that have been
- added/replaced in the objects dataspace. If this
- number doesnt match the number of entries in the
- merge dataspace, something probably went wrong.

- Dataspace.mui/MUIM_Dataspace_ReadIFF
-
- NAME
- MUIM_Dataspace_ReadIFF (V11)
-
- SYNOPSIS
- DoMethod(obj,MUIM_Dataspace_ReadIFF,struct IFFHandle *handle);
-
- FUNCTION
- Adds the contents of an IFF handle from iffparse.library to
- the dataspace. As always, objects with the same ID that
- are already in the dataspace will be replaced.
-
- This method does not look for any chunk types and chunk ids
- itself. Instead, it expects that you have already located
- the chunk which contains your data and does nothing
- but ReadChunkBytes() until all dataspace entries of
- the current chunk are read.
-
- NOTES
- Do not call MUIM_Dataspace_ReadIFF if your handle is
- positioned on chunks that were not written with
- MUIM_Dataspace_WriteIFF or strange things may happen!
-
- INPUTS
- handle - pointer to a struct IFFHandle from
- iffparse.library/AllocIFF(). The handle must
- already be open, initialized for reading and
- positioned on a chunk that was created with
- MUIM_Dataspace_WriteIFF.
-
- RESULT
- Returns 0 on success or some IFFERR_xxx on failure.

- Dataspace.mui/MUIM_Dataspace_Remove
-
- NAME
- MUIM_Dataspace_Remove (V11)
-
- SYNOPSIS
- DoMethod(obj,MUIM_Dataspace_Remove,ULONG id);
-
- FUNCTION
- This method removes an entry from the dataspace.
-
- INPUTS
- id - reference id
-
- RESULT
- Returns NULL if no entry with the given ID was found
- in the dataspace or some non NULL value on success.

- NAME
- MUIM_Dataspace_WriteIFF (V11)
-
- SYNOPSIS
- DoMethod(obj,MUIM_Dataspace_WriteIFF,struct IFFHandle *handle, ULONG type, ULONG id);
-
- FUNCTION
- Writes the contents of a dataspace to an IFF handle of
- iffparse.library.
-
- In detail, a chunk with the specified type and id is created
- with PushChunk(), the contents of the dataspace are written
- with WriteChunkBytes() and the chunk is terminated with
- PopChunk().
-
- INPUTS
- handle - pointer to a struct IFFHandle from
- iffparse.library/AllocIFF(). The handle must
- already be open and initialized for writing.
-
- type - type of chunk to create
- id - id of chunk to create
-
- RESULT
- Returns 0 on success or some IFFERR_xxx on failure.
