Class AbstractFilterBuilder

Object

AbstractFilterBuilder

public abstract class AbstractFilterBuilder
extends Object

This abstract class provides the common behavior to build the filters for the related semantic actions of parsing language process.

Builds Filter or Expression and their components (literal, functions, etc). It maintains the results of semantic actions in the stack used to build complex filters and expressions.

Warning: This component is not published. It is part of module implementation. Client module should not use this feature.

2.6
