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

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()

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.

Public Constructors

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

Since: 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

public final String getAttribute (String name)

Since: API Level 1

Returns the value of the attribute with the specified name.

Parameters
name the name of the attribute.
Returns
