本文整理了Java中org.bitcoinj.core.Block.getVersion()方法的一些代码示例，展示了Block.getVersion()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.getVersion()方法的具体详情如下：
包路径：org.bitcoinj.core.Block
类名称：Block
方法名：getVersion

Block.getVersion介绍

[英]Returns the version of the block data structure as defined by the Bitcoin protocol.
[中]返回比特币协议定义的块数据结构版本。

代码示例

代码示例来源：origin: dogecoin/libdohj

/**
 * Return block version without applying any filtering (i.e. for AuxPoW blocks
 * which structure version differently to pack in additional data).
 */
public final long getRawVersion() {
  return super.getVersion();

代码示例来源：origin: dogecoin/libdohj

@Override
public long getVersion() {
  // TODO: Can we cache the individual parts on parse?
  if (this.params instanceof AltcoinNetworkParameters) {
    // AuxPoW networks use the higher block version bits for flags and
    // chain ID.
    return getBaseVersion(super.getVersion());
  } else {
    return super.getVersion();
  }
}
