AbstractFreezable

public AbstractFreezable()

Method Detail

freeze

public void freeze()

Description copied from interface: Freezable

Freezes this object, making it immutable.

Specified by:

freeze in interface Freezable

isFrozen

public final boolean isFrozen()

Description copied from interface: Freezable

Determines whether this object is frozen, i.e. immutable.

Specified by:

isFrozen in interface Freezable

Returns:

True if Freezable.freeze() has been invoked, false otherwise.

assertMutable

public final void assertMutable()

Description copied from interface: Freezable

Asserts that this object is in a state to permit mutations. Classes that implement this interface should invoke this method prior to performing any mutation of internal state as a means of implementing the "frozen" usage contract.

Specified by:

assertMutable in interface Freezable

freeze

protected static void freeze(Object[] objects)

Iterates over the supplied objects and invokes Freezable.freeze() for any object that is an instance of Freezable.

Parameters:

objects - to make immutable

freeze

protected static void freeze(Object object)

Makes the supplied object immutable if it is an instance of Freezable.

Parameters:

object - to make immutable
