Enum Packer

java.lang.Object
java.lang.Enum<Packer>
org.apache.parquet.column.values.bitpacking.Packer
All Implemented Interfaces:
Serializable, Comparable<Packer>
public enum Packer extends Enum<Packer>
Factory for packing implementations

  • Enum Constant Details

    • BIG_ENDIAN

      public static final Packer BIG_ENDIAN
      packers who fill the Least Significant Bit First int and byte packer have the same result on Big Endian architectures

    • LITTLE_ENDIAN

      public static final Packer LITTLE_ENDIAN
      packers who fill the Most Significant Bit first int and byte packer have the same result on Little Endian architectures

  • Method Details

    • values

      public static Packer[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static Packer valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null

    • newIntPacker

      public abstract IntPacker newIntPacker(int width)
      Parameters:
      width - the width in bits of the packed values
      Returns:
      an int based packer

    • newBytePacker

      public abstract BytePacker newBytePacker(int width)
      Parameters:
      width - the width in bits of the packed values
      Returns:
      a byte based packer

    • newBytePackerVector

      public BytePacker newBytePackerVector(int width)

    • newBytePackerForLong

      public abstract BytePackerForLong newBytePackerForLong(int width)
      Parameters:
      width - the width in bits of the packed values
      Returns:
      a byte based packer for INT64
