Method Detail

toByteArray

public abstract java.nio.ByteBuffer toByteArray(Token token)

fromByteArray

public abstract Token fromByteArray(java.nio.ByteBuffer bytes)

asComparableBytes

public ByteSource asComparableBytes(Token token,
                                    ByteComparable.Version version)

Produce a byte-comparable representation of the token. See Token.asComparableBytes(org.apache.cassandra.utils.bytecomparable.ByteComparable.Version)

fromComparableBytes

public abstract Token fromComparableBytes(ByteSource.Peekable comparableBytes,
                                          ByteComparable.Version version)

Translates the given byte-comparable representation to a token instance. If the given bytes don't correspond to the encoding of an instance of the expected token type, an IllegalArgumentException may be thrown.

Parameters:

comparableBytes - A byte-comparable representation (presumably of a token of some expected token type).

Returns:

A new Token instance, corresponding to the given byte-ordered representation. If we were to call Token.asComparableBytes(ByteComparable.Version) on the returned object, we should get a ByteSource equal to the input one as a result.

Throws:

java.lang.IllegalArgumentException - if the bytes do not encode a valid token.

toString

public abstract java.lang.String toString(Token token)

fromString

public abstract Token fromString(java.lang.String string)

validate

public abstract void validate(java.lang.String token)
                       throws ConfigurationException

Throws:

ConfigurationException

serialize

public void serialize(Token token,
                      DataOutputPlus out)
               throws java.io.IOException

Throws:

java.io.IOException

serialize

public void serialize(Token token,
                      java.nio.ByteBuffer out)
               throws java.io.IOException

Throws:

java.io.IOException

fromByteBuffer

public Token fromByteBuffer(java.nio.ByteBuffer bytes,
                            int position,
                            int length)

byteSize

public int byteSize(Token token)
