Class Array

java.lang.Object
  |
  +--brutil.Array

All Implemented Interfaces:

Collection

public class Array

extends java.lang.Object

implements Collection

This is an automatically-resizing array list. It starts as a single array of objects (initialized to 'initialSize' field, and upon necessity grows and adds Subarrays of size 'capacityIncrement' to simulate a seamless array list.

Inner Class Summary

protected class

Array.Subarray Subarrays act as sub-modules for the Array.

Field Summary

protected static int	defaultCapacityIncrement
protected static int	defaultInitialCapacity
protected static int	STARTSIZE

Constructor Summary

Array()
Default Constructor, initial capacity = 10, increment = 10

Array(int initialCapacity)
Instantiates array with specified initial capacity.

Array(int initialCapacity, int capacityIncrement)
Instantiates array with specified initial capacity and capacityIncrement, uses the default value for the maximum number of SubArrays

Array(int initialCapacity, int capacityIncrement, int maxSize)
The main constructor.

Method Summary

void	clear() Sets every element in the Array to null
protected Array.Subarray	createSubarray(int size)
protected Array.Subarray[]	createSubarrayArray(int size)
java.lang.Object	get(int index) Gets the object at the specified index.
protected void	initMemory()
boolean	isEmpty() Returns true if empty
protected int	maxLength() Returns the maximum length of the Array.
brutil.behavior.FrequencyDist	predictTime(java.lang.String method, brutil.behavior.State currentState)
java.lang.Object	set(java.lang.Object obj, int index) Overwrites the element at this index to be the specified object and returns the former object.
int	size() Returns the size of the array from List interface.

Constructor Detail

Array

public Array()

Default Constructor, initial capacity = 10, increment = 10

Array

public Array(int initialCapacity)

Instantiates array with specified initial capacity.

Array

public Array(int initialCapacity,
             int capacityIncrement)

Instantiates array with specified initial capacity and capacityIncrement, uses the default value for the maximum number of SubArrays

Array

public Array(int initialCapacity,
             int capacityIncrement,
             int maxSize)

The main constructor. No parameter may be zero; zero-sized arrays are pointless.

Method Detail

predictTime

public brutil.behavior.FrequencyDist predictTime(java.lang.String method,
                                                 brutil.behavior.State currentState)

set

public java.lang.Object set(java.lang.Object obj,
                            int index)

Overwrites the element at this index to be the specified object and returns the former object.

get

public java.lang.Object get(int index)

Gets the object at the specified index.

size

public int size()

Returns the size of the array from List interface.

Specified by:

size in interface Collection

Specified by:

isEmpty in interface Collection

maxLength

protected int maxLength()

Returns the maximum length of the Array.

clear

public void clear()

Sets every element in the Array to null

Specified by:

clear in interface Collection

initMemory

protected void initMemory()

createSubarray

protected Array.Subarray createSubarray(int size)

createSubarrayArray
