Method Summary

Modifier and Type	Method	Description
byte[]	asBytes()	Returns the value of this hash code as a byte array.
int	asInt()	Returns the first four bytes of this hashcode's bytes, converted to an int value in little-endian order.
long	asLong()	Returns the first eight bytes of this hashcode's bytes, converted to a long value in little-endian order.
int	bits()	Returns the number of bits in this hash code; a positive multiple of 8.
(package private) boolean	equalsSameBits(HashCode that)	Returns whether this HashCode and that HashCode have the same value, given that they have the same number of bits.
long	padToLong()	If this hashcode has enough bits, returns asLong(), otherwise returns a long value with asBytes() as the least-significant bytes and 0x00 as the remaining most-significant bytes.

Method Detail

bits

public int bits()

Description copied from class: HashCode

Returns the number of bits in this hash code; a positive multiple of 8.

Specified by:

bits in class HashCode

asBytes

public byte[] asBytes()

Description copied from class: HashCode

Returns the value of this hash code as a byte array. The caller may modify the byte array; changes to it will not be reflected in this HashCode object or any other arrays returned by this method.

Specified by:

asBytes in class HashCode

asInt

public int asInt()

Description copied from class: HashCode

Returns the first four bytes of this hashcode's bytes, converted to an int value in little-endian order.

Specified by:

asInt in class HashCode

asLong

public long asLong()

Description copied from class: HashCode

Returns the first eight bytes of this hashcode's bytes, converted to a long value in little-endian order.

Specified by:

asLong in class HashCode

padToLong

public long padToLong()

Description copied from class: HashCode

If this hashcode has enough bits, returns asLong(), otherwise returns a long value with asBytes() as the least-significant bytes and 0x00 as the remaining most-significant bytes.

Specified by:

padToLong in class HashCode

writeBytesToImpl

void writeBytesToImpl(byte[] dest,
                      int offset,
                      int maxLength)

Specified by:

writeBytesToImpl in class HashCode

equalsSameBits

boolean equalsSameBits(HashCode that)

Description copied from class: HashCode

Returns whether this HashCode and that HashCode have the same value, given that they have the same number of bits.

Specified by:

equalsSameBits in class HashCode
