Provider.Service

extends Object

↳	java.security.Provider.Service

Class Overview

Service represents a service in the Java Security infrastructure. Each service describes its type, the algorithm it implements, to which provider it belongs and other properties.

Summary

Public Constructors
	Provider.Service(Provider provider, String type, String algorithm, String className, List<String> aliases, Map<String, String> attributes) Constructs a new instance of `Service` with the given attributes.

Public Methods
final String	getAlgorithm() Returns the name of the algorithm implemented by this `Service`.
final String	getAttribute(String name) Returns the value of the attribute with the specified `name`.
final String	getClassName() Returns the name of the class implementing this `Service`.
final Provider	getProvider() Returns the `Provider` this `Service` belongs to.
final String	getType() Returns the type of this `Service`.
Object	newInstance(Object constructorParameter) Creates and returns a new instance of the implementation described by this `Service`.
boolean	supportsParameter(Object parameter) Indicates whether this `Service` supports the specified constructor parameter.
String	toString() Returns a string containing a concise, human-readable description of this `Service`.

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 Provider.Service (Provider provider, String type, String algorithm, String className, List<String> aliases, Map<String, String> attributes)

Added in API level 1

Constructs a new instance of Service with the given attributes.

Parameters

provider	the provider to which this service belongs.
type	the type of this service (for example `KeyPairGenerator`).
algorithm	the algorithm this service implements.
className	the name of the class implementing this service.
aliases	`List` of aliases for the algorithm name, or `null` if the implemented algorithm has no aliases.
attributes	`Map` of additional attributes, or `null` if this `Service` has no attributed.

Throws

NullPointerException	if `provider, type, algorithm` or `className` is `null`.

Public Methods

Added in API level 1

Returns the name of the algorithm implemented by this Service.

Returns

the name of the algorithm implemented by this Service.

public final String getAttribute (String name)

Added in API level 1

Returns the value of the attribute with the specified name.

Parameters

name	the name of the attribute.

Returns

the value of the attribute, or null if no attribute with the given name is set.

Throws

the type of this Service.

public Object newInstance (Object constructorParameter)

Added in API level 1

Creates and returns a new instance of the implementation described by this Service.

Parameters

constructorParameter	the parameter that is used by the constructor, or `null` if the implementation does not declare a constructor parameter.

Returns

a new instance of the implementation described by this Service.

Throws

NoSuchAlgorithmException	if the instance could not be constructed.
InvalidParameterException	if the implementation does not support the specified `constructorParameter`.

public boolean supportsParameter (Object parameter)

Added in API level 1

Indicates whether this Service supports the specified constructor parameter.
