Class ChecksumIndexOutput

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable

    public class ChecksumIndexOutput
    extends IndexOutput
    Writes bytes through to a primary IndexOutput, computing checksum. Note that you cannot use seek().

    • Method Detail

      • writeByte

        public void writeByte​(byte b)
                       throws java.io.IOException
        Description copied from class: DataOutput
        Writes a single byte.

        The most primitive data type is an eight-bit byte. Files are accessed as sequences of bytes. All other data types are defined as sequences of bytes, so file formats are byte-order independent.

        Specified by:
        writeByte in class DataOutput
        Throws:
        java.io.IOException
        See Also:
        DataInput.readByte()
      • writeBytes

        public void writeBytes​(byte[] b,
                               int offset,
                               int length)
                        throws java.io.IOException
        Description copied from class: DataOutput
        Writes an array of bytes.
        Specified by:
        writeBytes in class DataOutput
        Parameters:
        b - the bytes to write
        offset - the offset in the byte array
        length - the number of bytes to write
        Throws:
        java.io.IOException
        See Also:
        DataInput.readBytes(byte[],int,int)

                   throws java.io.IOException
        Description copied from class: IndexOutput
