本文整理了Java中java.nio.ShortBuffer.clear()方法的一些代码示例,展示了ShortBuffer.clear()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。ShortBuffer.clear()方法的具体详情如下:包路径:java.nio.ShortBuffer类名...
java.nio.ByteBuffer中flip,rewind,clear方法的区别 对缓冲区的读写操作首先要知道缓冲区的下限.上限和当前位置.下面这些变量的值对Buffer类中的某些操作有着至关重要的作用: limit:所有对Buffer读写操作都会以limit变量的值作为上限. position:代表对缓冲区进行读写时,当前游标的位置. capacity:代表缓冲区的最大容量...
