Methods Summary
public org.apache.poi.poifs.storage.ListManagedBlock[]	fetchBlocks(int startBlock) get the blocks making up a particular stream in the list. The blocks are removed from the list. param startBlock the index of the first block in the stream return the stream as an array of correctly ordered blocks exception IOException if blocks are missing if (_bat == null) { throw new IOException( "Improperly initialized list: no block allocation table provided"); } return _bat.fetchBlocks(startBlock, this);
public org.apache.poi.poifs.storage.ListManagedBlock	remove(int index) remove and return the specified block from the list param index the index of the specified block return the specified block exception IOException if the index is out of range or has already been removed ListManagedBlock result = null; try { result = _blocks[ index ]; if (result == null) { throw new IOException("block[ " + index + " ] already removed"); } _blocks[ index ] = null; } catch (ArrayIndexOutOfBoundsException ignored) { throw new IOException("Cannot remove block[ " + index + " ]; out of range"); } return result;
public void	setBAT(org.apache.poi.poifs.storage.BlockAllocationTableReader bat) set the associated BlockAllocationTable param bat the associated BlockAllocationTable exception IOException if (_bat != null) { throw new IOException( "Attempt to replace existing BlockAllocationTable"); } _bat = bat;
protected void	setBlocks(org.apache.poi.poifs.storage.ListManagedBlock[] blocks) provide blocks to manage param blocks blocks to be managed _blocks = blocks;
public void	zap(int index) remove the specified block from the list param index the index of the specified block; if the index is out of range, that's ok if ((index >= 0) && (index < _blocks.length)) { _blocks[ index ] = null; }
