public UID()
UID
that is unique over time with
respect to the host that it was generated on.
public UID(short num)
UID
.
There are 216 possible such well-known ids.
A UID
created via this constructor will not
clash with any UID
s generated via the no-arg
constructor.
num
- number for well-known UID

public int hashCode()
UID
.
UID
Object.equals(java.lang.Object)
,
Hashtable
public boolean equals(Object obj)
UID
for
equality.
This method returns true
if and only if the
specified object is a UID
instance with the same
unique
, time
, and count
values as this one.
obj
- the object to compare this UID
to
true
if the given object is equivalent to
this one, and false
otherwiseObject.hashCode()
,
Hashtable
public String toString()
UID
.
UID
public void write(DataOutput out) throws IOException
UID
to
a DataOutput
instance.
Specifically, this method first invokes the given stream's
DataOutput.writeInt(int)
method with this UID
's
unique
value, then it invokes the stream's
DataOutput.writeLong(long)
method with this UID
's
time
value, and then it invokes the stream's
DataOutput.writeShort(int)
method with this UID
's
count
value.
out
- the DataOutput
instance to write
this UID
to
IOException
- if an I/O error occurs while performing
this operationpublic static UID read(DataInput in) throws IOException
UID
instance by
unmarshalling a binary representation from an
DataInput
instance.
Specifically, this method first invokes the given stream's
DataInput.readInt()
method to read a unique
value,
then it invoke's the stream's
DataInput.readLong()
method to read a time
value,
then it invoke's the stream's
DataInput.readShort()
method to read a count
value,
and then it creates and returns a new UID
instance
that contains the unique
, time
, and
count
values that were read from the stream.
in
- the DataInput
instance to read
UID
from
UID
instance
IOException
- if an I/O error occurs while performing
this operation
