Method Details

visitFunction

public T visitFunction(RqlParser.FunctionContext ctx)

Description copied from class: RqlBaseVisitor

Visit a parse tree produced by the function 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:

visitFunction in interface RqlVisitor<T>

Overrides:

visitFunction in class RqlBaseVisitor<T>

Parameters:

ctx - the parse tree

Returns:

the visitor result

applyFunction

public abstract T applyFunction(String functionName,
 List<Object> arguments)
