关于build tool的构想 从Ant说起[8]

java代码

interface CommandBinder{

Command bind（Object v）;

}

然后定义BoundCommand类

java代码

class BoundCommand implements Command{

private final Command c;

private final CommandBinder c;

public Object execute（CommandContext ctxt）{

final Object v =return cexecute（ctxt）;

return cbind（v）execute（ctxt）;

}

BoundCommand （Command c CommandBinder c）{

thisc = c;

thisc = c;

}

}

先透露一下这个BoundCommand非常重要就是它负责在不同的command间传递信息
