Class CharQueue

java.lang.Object

org.alfresco.module.org_alfresco_module_wcmquickstart.benchmark.CharQueue

public class CharQueue
extends Object

This is based on the work done by Lawrence Kesteloot. Keeps a fixed-length queue of characters. There are only three operations on the queue: set the whole thing; append a character (dropping the first); and retreive the whole thing. This is useful as a moving window on a text stream.

Constructor Detail

CharQueue

public CharQueue(int length)

Create the queue with a fixed length. The queue will be filled with the value 0, so don't use the toString() method until the queue has been filled with either set() or put().

Method Detail

set

public void set(String s)

Sets the contents of the queue. The length of the string must be the same as the length passed to the constructor.

put

public void put(char c)

Appends the character to the queue. If the resulting queue would be longer than the length set in the constructor, then the first character is dropped.

Parameters:

c -

toString

public String toString()

Returns the contents of the queue as a string. This does not take into account the number of characters that have been put into the queue. The returned string's length is always the length passed to the constructor.

Overrides:

toString in class Object
