# FastEL 

#### 项目介绍

* FastEL 快速的表达式解析器

#### 使用说明

* 引用JAR包

    ``` xml

        

            org.jiuwo

            fastel

            1.0.6

        

    ```   

* 具体使用

    ``` java

        Expression expression = new ExpressionImpl("2*(3+5)");

        result = expression.evaluate();

        Assert.assertEquals(16L, result);

        

        result = expression

                 .parseExpression("parseInt('2')")

                 .evaluate();

        Assert.assertEquals(2, result);

        

        result = expression

                .parseExpression("Math.abs(-123)")

                .evaluate();

        Assert.assertEquals(123.0, result);

        

    ```
