本文整理了Java中io.prestosql.spi.block.Block.compareTo()方法的一些代码示例，展示了Block.compareTo()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。Block.compareTo()方法的具体详情如下：
包路径：io.prestosql.spi.block.Block
类名称：Block
方法名：compareTo

Block.compareTo介绍

[英]Compares the byte sequences at offset in the value at positionto the byte sequence at otherOffset in the value at otherPositionin otherBlock. This method must be implemented if @{code getSlice} is implemented.
[中]将位置处的值中偏移量处的字节序列与其他块中其他位置处的值中其他偏移量处的字节序列进行比较。如果实现了@{code getSlice}，则必须实现此方法。
