Class InvokeExpression

  • All Implemented Interfaces:

    public class InvokeExpression
    extends Expression
    Expression representing invocation of a method. This may be an aggregate in a result clause (like "count(this)"), or a method on a class, or a function. The "left" expression is what we are invoking on. This is typically a PrimaryExpression, or an InvokeExpression. This then allows chaining of invocations.

      • toStringWithoutAlias

        public String toStringWithoutAlias()
        Method to return the string form of this without the alias component. This is useful when we want to compare expressions in a query compile, and the alias is not important to the comparison. Returns a String of the form "InvokeExpression{[left].methodName(args)}" or "InvokeExpression{STATIC.methodName(args)}".
        The string form
      • toString

        public String toString()
        Method to return the string form of this expression. Returns a String of the form "InvokeExpression{[left].methodName(args)} AS alias" or "InvokeExpression{STATIC.methodName(args)} AS alias". where it only adds the "AS alias" when the alias is non-null.
