Parameters:

row - the row index (zero-based).

column - the column index (zero-based).

object - the object.

equals

public boolean equals(java.lang.Object o)

Tests this paint table for equality with another object (typically also an ObjectTable).

Parameters:

o - the other object.

Returns:

A boolean.

protected void writeSerializedData(java.io.ObjectOutputStream stream,
                                   java.lang.Object o)
                            throws java.io.IOException

Handles the serialization of an single element of this table.

Parameters:

stream - the stream which should write the object

o - the object that should be serialized

Throws:

java.io.IOException - if an IO error occured

readSerializedData

protected java.lang.Object readSerializedData(java.io.ObjectInputStream stream)
                                       throws java.io.OptionalDataException,
                                              java.lang.ClassNotFoundException,
                                              java.io.IOException

Handles the deserialization of a single element of the table.

Parameters:

stream - the object input stream from which to read the object.

Returns:

the deserialized object

Throws:
