Method Detail

makeTextNode

protected int makeTextNode(CharSequence chars,
                           int len)

Create a text node. Separate method so it can be overridden

Overrides:

makeTextNode in class TinyBuilder

Parameters:

chars - the contents of the text node

len - the length of the text node

attribute

public void attribute(int nameCode,
                      int typeCode,
                      CharSequence value,
                      int locationId,
                      int properties)
               throws XPathException

For attribute nodes, the commoning-up of stored values is achieved simply by calling intern() on the string value of the attribute.

Specified by:

attribute in interface Receiver

Overrides:

attribute in class TinyBuilder

Parameters:

nameCode - The name of the attribute, as held in the name pool

typeCode - The type of the attribute, as held in the name pool. The additional bit NodeInfo.IS_DTD_TYPE may be set to indicate a DTD-derived type.

value - the string value of the attribute

locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

properties - Bit significant value. The following bits are defined:

DISABLE_ESCAPING

Disable escaping for this attribute

NO_SPECIAL_CHARACTERS

Attribute value contains no special characters

Throws:

XPathException
