public abstract class AbstractLinear

extends AbstractStructure

implements Linear

An abstract implemtation of linear data structures. Linear structures have completely determined add and remove methods. Linear structures are often used to store the the state of a recursively solved problem and stacks and queues are classic examples of such structures.

public AbstractLinear()

Method Detail

empty

public boolean empty()

Determine if there are elements within the linear.

Specified by:

empty in interface Linear

Returns:

true if the linear structure is empty; false otherwise

remove

public java.lang.Object remove(java.lang.Object o)

Removes value from the linear structure. Not implemented (by default) for linear classes.

Specified by:

remove in interface Structure

Parameters:

o - value matching the value to be removed

Returns:

returns the value that was replaced, or null if none.
