canInsertData

public short canInsertData(int offset,
                           java.lang.String arg)
                    throws DOMException

Determines if data can be inserted.

Parameters:

offset - Offset.

count - Number of 16-bit units to delete.

Returns:

nodeValidity

public short nodeValidity(boolean deep,
                          short wFValidityCheckLevel)

Determines if the node is valid relative to the validation type specified in valType. This operation doesn't normalize before checking if it is valid. To do so, one would need to explicitly call a normalize method. The difference between this method and the validateDocument method on the DocumentVAL interface is that validateDocument only checks to determine whether the entire document is valid.

Parameters:

wFValidityCheckLevel - Flag to tell at what level validity and well-formedness checking is done.

Returns:

A validation state constant.
