Method Detail

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException

Write this out.

Specified by:

writeExternal in interface java.io.Externalizable

---

readExternal

public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException

Read this in

Specified by:

readExternal in interface java.io.Externalizable

---

getTypeFormatId

public int getTypeFormatId()

Return my format identifier.

Specified by:

getTypeFormatId in interface org.apache.derby.iapi.services.io.TypedFormat

---

writeMSB

private static void writeMSB(char[] data,
                             int offset,
                             long value,
                             int nbytes)

---

readMSB

private static long readMSB(java.io.StringReader sr)

---

equals

public boolean equals(java.lang.Object otherObject)

Implement value equality.

---

hashCode

public int hashCode()

Provide a hashCode which is compatible with the equals() method.

---

toString

public java.lang.String toString()

Specified by:

toANSIidentifier in interface org.apache.derby.catalog.UUID

---

stringWorkhorse

public java.lang.String stringWorkhorse(char separator)

Private workhorse of the string making routines.

---

toByteArray

public byte[] toByteArray()

Store this UUID in a byte array. Arrange the bytes in the UUID in the same order the code which stores a UUID in a string does.

Specified by:

toByteArray in interface org.apache.derby.catalog.UUID

---

cloneMe

public org.apache.derby.catalog.UUID cloneMe()

Clone this UUID.

Specified by:

cloneMe in interface org.apache.derby.catalog.UUID

---

toHexString

public java.lang.String toHexString()

Description copied from interface: org.apache.derby.catalog.UUID
