List of prepareDecoding() Examples

Examples of prepareDecoding()

org.apache.hadoop.hbase.io.encoding.HFileBlockDecodingContext.prepareDecoding()
Perform all actions that need to be done before the encoder's real decoding process. Decompression needs to be done if {@link #getCompression()} returns a valid compressionalgorithm. @param onDiskSizeWithoutHeader numBytes after block and encoding headers @param uncompressedSizeWithoutHeader numBytes without header required to store the block afterdecompressing (not decoding) @param blockBufferWithoutHeader ByteBuffer pointed after the header but before the data @param onDiskBlock on disk bytes to be decoded @param offset data start offset in onDiskBlock @throws IOException

Examples of org.apache.hadoop.hbase.io.encoding.HFileBlockDecodingContext.prepareDecoding()

    HFileBlock unpacked = new HFileBlock(this);
    unpacked.allocateBuffer(); // allocates space for the decompressed block


    HFileBlockDecodingContext ctx = blockType == BlockType.ENCODED_DATA ?
      reader.getBlockDecodingContext() : reader.getDefaultBlockDecodingContext();
    ctx.prepareDecoding(unpacked.getOnDiskSizeWithoutHeader(),
      unpacked.getUncompressedSizeWithoutHeader(), unpacked.getBufferWithoutHeader(),
      this.getBufferReadOnlyWithHeader().array(), this.headerSize());


    // Preserve the next block's header bytes in the new block if we have them.
    if (unpacked.hasNextBlockHeader()) {
