Method Detail

writeBinary

public void writeBinary(java.io.DataOutputStream dos)
                 throws java.io.IOException

Writes this state (in binary format) to a data output stream. For the EmptyState, nothing is written.

Specified by:

writeBinary in interface ComponentState

Parameters:

dos - output stream to write model to

Throws:

java.io.IOException - if an I/O error occurred

readBinary

public void readBinary(java.io.DataInputStream dis)
                throws java.io.IOException

Read this state (in binary format) from a data input stream. For the EmptyState, nothing is read.

Specified by:

readBinary in interface ComponentState

Parameters:

dis - input stream to read model from

Throws:

java.io.IOException - if an I/O error occurred or if the input is incompatible with the current state configuration.

set

public void set(ComponentState state)

Sets this state by copying the value from an existing state object.

Specified by:

set in interface ComponentState

Parameters:

state - state object to copy

Throws:

java.lang.IllegalArgumentException - if the state objects are incompatible

equals

public boolean equals(ComponentState state)

Description copied from interface: ComponentState

Returns true if this state equals another component state.

Specified by:

equals in interface ComponentState

Parameters:

state - state to compare to

duplicate

public ComponentState duplicate()

Create a duplicate of this state which can be used for storing this state's values.

Specified by:

duplicate in interface ComponentState

Returns:

duplicate of this state
