To avoid multiple type checks, a group mask was include, as described below.

Method Detail

getGrouping

int getGrouping()

Returns the mask informing the caller as to the type of object they are dealing with.

findChildElement

Element findChildElement(String name)

Convinience method which will search for the specified element within it's children. This is typically implemented recursively, and as such may be expensive to execute (so don't call me too much if you want to be fast).

Parameters:

name - The Element LocalName (namespace and prefix should not be included)

Returns:

Element or null if not found.

getMaxOccurs

int getMaxOccurs()

returns the max number of allowable occurences within the xml schema for this construct.

getMinOccurs

int getMinOccurs()

returns the min number of allowable occurences within the xml schema for this construct.

findChildElement

Element findChildElement(String localName,
                       URI namespaceURI)
