Class Expand

java.lang.Object

io.parsingdata.metal.expression.value.Expand

All Implemented Interfaces:

ValueExpression

public class Expand
extends Object
implements ValueExpression

A ValueExpression that expands a result by copying and concatenating it a specified amount of times.

An Expand expression has two operands: base and count (both ValueExpressions). Both operands are evaluated. An IllegalStateException is thrown if evaluating count yields more than a single value. Multiple copies of the result of evaluating base are concatenated. The amount of copies equals the result of evaluating count.
