public void load(DataInputStream in)

This will read in whatever data is neccessary to create this entry

Specified by:

load in class ConstantPoolEntry

Parameters:

in - the stream to read the data from

toString

public String toString()

This will print a string rep of the class

Overrides:

toString in class Object

toBytes

public byte[] toBytes()
               throws IOException

This will take the entry and convert it into bytes.

Specified by:

toBytes in class ConstantPoolEntry

Returns:

the bytes that represent this entry.

IOException
