Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Constructors

public RC5ParameterSpec (int version, int rounds, int wordSize)

Added in API level 1

Creates a new RC5ParameterSpec instance with the specified version, round count an word size (in bits).

Parameters

version	the version.
rounds	the round count.
wordSize	the word size (in bits).

public RC5ParameterSpec (int version, int rounds, int wordSize, byte[] iv)

Added in API level 1

Creates a new RC5ParameterSpec instance with the specified version, round count, word size (in bits) and an initialization vector.

The size of the initialization vector must be at least 2 * (wordSize / 8) bytes which are copied to protect them against modification.

Parameters

version	the version.
rounds	the round count.
wordSize	the word size (in bits).
iv	the initialization vector.

Throws

IllegalArgumentException	if the initialization vector is null or shorter than `2 * (wordSize / 8)`.

public RC5ParameterSpec (int version, int rounds, int wordSize, byte[] iv, int offset)

Added in API level 1

Creates a new RC5ParameterSpec instance with the specified version, round count, wordSize (in bits), an initialization vector and an offset.

The size of the initialization vector must be at least offset + (2 * (wordSize / 8)) bytes. The bytes starting at offset are copied to protect them against modification.

Parameters

version	the version.
rounds	the round count.
wordSize	the word size (in bits).
iv	the initialization vector.
offset	the offset in the initialization vector.

Throws

IllegalArgumentException	if the initialization vector is null of shorter than `offset + (2 * (wordSize / 8))`.
ArrayIndexOutOfBoundsException	if `offset` is negative.

Public Methods

public boolean equals (Object obj)

Added in API level 1

Compares the specified object with this RC5ParameterSpec instance.

Parameters

obj	the object to compare.

Returns

true if version, round count, word size and initializaion vector of both objects are equal, otherwise false.

public byte[] getIV ()

Added in API level 1

Returns a copy of the initialization vector.

Returns

a copy of the initialization vector, or null if none specified.

public int getRounds ()

Added in API level 1

Returns the round count.

Returns

the round count.

public int getVersion ()

Added in API level 1

Returns the version.

Returns

the version.

public int getWordSize ()

Added in API level 1

Returns the word size (in bits).

Returns

the word size (in bits).

public int hashCode ()

Added in API level 1

Returns the hash code of this RC5ParameterSpec instance.

Returns

the hash code.
