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.

Protected Methods

protected abstract byte[] engineGetEncoded ()

Added in API level 1

Returns the parameters in their default encoding format. The default encoding format is ASN.1.

Returns
`byte[]`	the encoded parameters.

Throws
`IOException`	if this `AlgorithmParametersSpi` has already been initialized, or if this parameters could not be encoded.

protected abstract byte[] engineGetEncoded (String format)

Added in API level 1

Returns the parameters in the specified encoding format.

Parameters
`format`	`String`: the name of the encoding format.

Returns
`byte[]`	the encoded parameters.

Throws
`IOException`	if this `AlgorithmParametersSpi` has already been initialized, or if this parameters could not be encoded.

protected abstract T engineGetParameterSpec (Class<T> paramSpec)

Added in API level 1

Returns the AlgorithmParameterSpec for this AlgorithmParametersSpi.

Parameters
`paramSpec`	`Class`: the type of the parameter specification in which this parameters should be converted.

Returns
`T`	the `AlgorithmParameterSpec` for this `AlgorithmParametersSpi`.

Throws
`InvalidParameterSpecException`	if this `AlgorithmParametersSpi` has already been initialized, or if this parameters could not be converted to the specified class.

protected abstract void engineInit (byte[] params)

Added in API level 1

Initializes this AlgorithmParametersSpi with the specified byte[] using the default decoding format for parameters. The default encoding format is ASN.1.

Parameters
`params`	`byte`: the encoded parameters.

Throws
`IOException`	if this `AlgorithmParametersSpi` has already been initialized, or the parameter could not be encoded.

protected abstract void engineInit (byte[] params, String format)

Added in API level 1

Initializes this AlgorithmParametersSpi with the specified byte[] using the specified decoding format.

Parameters
`params`	`byte`: the encoded parameters.
`format`	`String`: the name of the decoding format.

Throws
`IOException`	if this `AlgorithmParametersSpi` has already been initialized, or the parameter could not be encoded.

protected abstract void engineInit (AlgorithmParameterSpec paramSpec)

Added in API level 1

Initializes this AlgorithmParametersSpi with the specified AlgorithmParameterSpec.

Parameters
`paramSpec`	`AlgorithmParameterSpec`: the parameter specification.

Throws
`InvalidParameterSpecException`	if this `AlgorithmParametersSpi` has already been initialized or the given `paramSpec` is not appropriate for initializing this `AlgorithmParametersSpi`.

protected abstract String engineToString ()

Added in API level 1

Returns a string containing a concise, human-readable description of this AlgorithmParametersSpi.

Returns
`String`	a printable representation for this `AlgorithmParametersSpi`.
