Method Detail

visitField_filter

public FilterPredicate visitField_filter(PredicateParser.Field_filterContext ctx)

Description copied from class: PredicateBaseVisitor

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

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

Specified by:

visitField_filter in interface PredicateVisitor<FilterPredicate>

Overrides:

visitField_filter in class PredicateBaseVisitor<FilterPredicate>

Parameters:

ctx - the parse tree

Returns:

the visitor result

getColname

public static String getColname(String text)
