## Member Function Documentation

data_type * XalanElemEmptyAllocator::create ( | StylesheetConstructionContext & constructionContext,
| Stylesheet & stylesheetTree,
| const XalanDOMString * elementName = 0 )

Construct an instance.

Parameters:

  constructionContext | The current construction context
  stylesheetTree | The stylesheet containing element
  elementName | The name of element. Can be 0.

data_type * XalanElemEmptyAllocator::create ( | StylesheetConstructionContext & constructionContext,
| Stylesheet & stylesheetTree,
| int lineNumber,
| int columnNumber,
| const XalanDOMString * elementName = 0 )

Construct an instance.

Parameters:

  constructionContext | The current construction context
  stylesheetTree | The stylesheet containing element
  lineNumber | The line number in the document
  columnNumber | The column number in the document
  elementName | The name of element. Can be 0.

Returns:
  A pointer to the new instance.

bool XalanElemEmptyAllocator::destroy ( | data_type * theObject )`[]`

Destroy an instance previously created.

Parameters:

  theObject | A pointer to the instance to destroy.

Returns:
  true if the instance was destroyed, false if not.

size_type XalanElemEmptyAllocator::getBlockCount ( | ) const`[]`

Get the number of ArenaBlocks currently allocated.

Returns:
  The number of blocks.

size_type XalanElemEmptyAllocator::getBlockSize ( | ) const`[]`

Get size of an ArenaBlock, that is, the number of objects in each block.

Returns:
  The size of the block

bool XalanElemEmptyAllocator::ownsObject ( | const data_type * theObject )`[]`

Determine if an object is owned by the allocator...

void XalanElemEmptyAllocator::reset ( | )`[]`

Delete all objects from the allocator.
