◆ getMaxLength()

int javolution.xml.internal.stream.EntitiesImpl.getMaxLength ( )

Returns the length of the largest entity defined (default

1

).

Here is the caller graph for this function:

◆ replaceEntity()

int javolution.xml.internal.stream.EntitiesImpl.replaceEntity	(	char[]	buffer,
		int	start,
		int	length
	)		throws XMLStreamException

Replaces the entity at the specified position. The five predefined XML entities "&lt;", "&gt;", "&apos;", "&quot;", "&amp;" as well as character refererences (decimal or hexadecimal) are always recognized.

Parameters

buffer	the data buffer.
start	the index of entity first character (index of '&')

Returns: the length of the replacement entity (including ';')

Exceptions

XMLStreamException if the entity is not recognized.
