Example 98 with Binding

use of groovy.lang.Binding in project groovy by apache.

the class Eval method me.

/**
 * Evaluates the specified String expression and makes the parameter available inside
 * the script, returning the result. For example, this code binds the 'x' variable:
 * <pre class="groovyTestCase">
 * assert Eval.me('x', 2, ' x * 4 + 2') == 10

Example 99 with Binding

use of groovy.lang.Binding in project groovy by apache.

the class Eval method xy.

/**
 * Evaluates the specified String expression and makes the first two parameters available inside
 * the script bound to variables named 'x' and 'y' respectively, returning the result. For example,
 * this code executes without failure:
