decompressAndPrependSchemaHeader
public java.nio.ByteBuffer decompressAndPrependSchemaHeader(byte[] data, int offset, int length, int schemaHeader) throws java.io.IOException
Description copied from class:VeniceCompressor
This method tries to decompress data and maybe prepend the schema header. The returned ByteBuffer will be backed by byte array that starts with schema header, followed by the decompressed data. The ByteBuffer will be positioned at the beginning of the decompressed data and the remaining of the ByteBuffer will be the length of the decompressed data.- Specified by:
