public FilterPredicateVisitor()

Method Detail

visitCompilationUnit

public FilterPredicate visitCompilationUnit(PredicateParser.CompilationUnitContext ctx)

Description copied from class: PredicateBaseVisitor

Visit a parse tree produced by PredicateParser.compilationUnit().

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

Specified by:

visitCompilationUnit in interface PredicateVisitor<FilterPredicate>

Overrides:

visitCompilationUnit in class PredicateBaseVisitor<FilterPredicate>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitPredicate

public FilterPredicate visitPredicate(PredicateParser.PredicateContext ctx)

Description copied from class: PredicateBaseVisitor

Visit a parse tree produced by PredicateParser.predicate().

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

Specified by:

visitPredicate in interface PredicateVisitor<FilterPredicate>

Overrides:

visitPredicate in class PredicateBaseVisitor<FilterPredicate>

Parameters:

ctx - the parse tree

Returns:

the visitor result
