Method Details

visitGroup

public Predicate<T> visitGroup(RqlParser.GroupContext ctx)

Description copied from class: RqlBaseVisitor

Visit a parse tree produced by the group labeled alternative in RqlParser.expression().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitGroup in interface RqlVisitor<T>

Overrides:

visitGroup in class RqlBaseVisitor<Predicate<T>>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitAnd

public Predicate<T> visitAnd(RqlParser.AndContext ctx)

Description copied from class: RqlBaseVisitor

Visit a parse tree produced by the and labeled alternative in RqlParser.expression().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitAnd in interface RqlVisitor<T>

Overrides:

visitAnd in class RqlBaseVisitor<Predicate<T>>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitOr

public Predicate<T> visitOr(RqlParser.OrContext ctx)

Description copied from class: RqlBaseVisitor

Visit a parse tree produced by the or labeled alternative in RqlParser.expression().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitOr in interface RqlVisitor<T>

Overrides:

visitOr in class RqlBaseVisitor<Predicate<T>>

Parameters:
