欢迎使用 FastJsp 开发框架! 编译说明： * 若要生成Api Javadoc文档

package com.onetsoft.fastjsp;

class LinkPool implements Lifecycle{
    private LinkImpl[] a = new LinkImpl[0];
    private int size = 0;

    public void recycle() {
        for (int i = 0; i < size; i++) {
           a[i].recycle();
       }
        size = 0;
    }

    LinkImpl get() {
        ensurePool(size + 1);
        return a[size++];
    }

    public void ensurePool(int size) {
        if (size > a.length) {
            LinkImpl[] a = new LinkImpl[size];
            System.arraycopy(this.a, 0, a, 0, this.a.length);
            a[size - 1] = new LinkImpl();
            this.a = a;
        }
    }
