Interface QueryTreeVisitor<T>

public interface QueryTreeVisitor<T>

Defines an interface of the visitor invoked by the walker. the type of the context object accompanying visited tree nodes.

Method Summary

void	visitConjunction(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents a conjunction (logical and) of conditions.
void	visitContains(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents that a field must contain a value.
void	visitDisjunction(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents a disjunction (logical or) of conditions.
void	visitEqual(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents that a field value must be greater than or equal to some specified value.
void	visitFuzzy(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents a text field that is subject to query rewrite.
void	visitGreaterOrEqual(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents an inequality between a field and value.
void	visitGreaterThan(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents that a field value must be greater than some specified value.
void	visitLessOrEqual(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents that a field value must be less than or equal to some specified value.
void	visitLessThan(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents that a field value must be less than some specified value.
void	visitLiteral(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents a text field that must not be altered.
void	visitNegation(QueryTreeWalker<T> walker, Tree node, T context) Visits a node that represents a negation of conditions.
void	visitOther(QueryTreeWalker<T> walker, Tree node, T context) Catch-all method for future type of query nodes.
