TrustManagerFactorySpi

AI-generated Key Takeaways

• TrustManagerFactorySpi is a Service Provider Interface (SPI) for the TrustManagerFactory class, enabling cryptographic service providers to implement custom trust manager factories.

• Providers must implement all abstract methods within TrustManagerFactorySpi to supply their trust manager factory implementation.

• TrustManagerFactorySpi provides methods to initialize the factory with a keystore or provider-specific parameters and retrieve trust managers.

• It's used to establish trust in SSL/TLS connections by managing trust material like certificate authorities.

public abstract class TrustManagerFactorySpi extends Object

This class defines the Service Provider Interface (SPI) for the TrustManagerFactory class.

All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply the implementation of a particular trust manager factory.

Inherited Method Summary

From class java.lang.Object

Object	clone() Creates and returns a copy of this Object.
boolean	equals(Object obj) 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(long timeout, 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 timeout) 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() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

Public Constructors

public TrustManagerFactorySpi ()

Protected Methods

protected abstract TrustManager[] engineGetTrustManagers ()

Returns one trust manager for each type of trust material.

Returns

• the trust managers

Throws

IllegalStateException	if the factory is not initialized.

protected abstract void engineInit (KeyStore ks)

Initializes this factory with a source of certificate authorities and related trust material.

Parameters

ks	the key store or null

Throws

KeyStoreException	if this operation fails

See Also

• TrustManagerFactory.init(KeyStore)

protected abstract void engineInit (ManagerFactoryParameters spec)

Initializes this factory with a source of provider-specific key material.

In some cases, initialization parameters other than a keystore may be needed by a provider. Users of that particular provider are expected to pass an implementation of the appropriate ManagerFactoryParameters as defined by the provider. The provider can then call the specified methods in the ManagerFactoryParameters implementation to obtain the needed information.

Parameters

spec	an implementation of a provider-specific parameter specification

Throws

InvalidAlgorithmParameterException	if there is problem with the parameters
