Interface Precedence

All Known Implementing Classes:

PostprocessorInputHandler

public interface Precedence

Interface that can be used to assign a invokation precedence to input handlers. For each scope input handlers will be invoked in the order of their precedence. Input handlers that have different precedences will effect multi-pass parsing on the input scope.

GraphML handlers for GraphML elements like graph, node and edge have default precedence GRAPHML_PRECEDENCE. Input handlers with smaller precedence will be invoked before and input handlers with bigger precedence will be invoked after the standard GraphML elements are parsed.

Field Summary

static int

GRAPHML_PRECEDENCE Symbolic constant for the default handler precedence.

Method Summary

int	getPrecedence() Get the precedence value of the input handler.

Field Detail

GRAPHML_PRECEDENCE

public static final int GRAPHML_PRECEDENCE

Symbolic constant for the default handler precedence. Note: input handlers with a lower precedence will be called before any "normal" (i.e. not data) child elements of the current graph element are parsed.

Method Detail

getPrecedence

public int getPrecedence()

Get the precedence value of the input handler.

Returns:

the precedence value of the handler
