java.security.cert
class CertPathValidatorSpi

java.lang.Object java.security.cert.CertPathValidatorSpi

public abstract class CertPathValidatorSpi
extends Object

The Service Provider Interface (SPI) for the {@link CertPathValidator CertPathValidator} class. All CertPathValidator implementations must include a class (the SPI class) that extends this class (CertPathValidatorSpi) and implements all of its methods. In general, instances of this class should only be accessed through the CertPathValidator class. For details, see the Java Cryptography Architecture.

Concurrent Access

Instances of this class need not be protected against concurrent access from multiple threads. Threads that need to access a single CertPathValidatorSpi instance concurrently should synchronize amongst themselves and provide the necessary locking before calling the wrapping CertPathValidator object.

However, implementations of CertPathValidatorSpi may still encounter concurrency issues, since multiple threads each manipulating a different CertPathValidatorSpi instance need not synchronize.

The default constructor.

engineValidate

public abstract CertPathValidatorResult engineValidate(CertPath certPath,
                                                       CertPathParameters params)
                                                throws CertPathValidatorException,
                                                       InvalidAlgorithmParameterException

Validates the specified certification path using the specified algorithm parameter set.

The CertPath specified must be of a type that is supported by the validation algorithm, otherwise an InvalidAlgorithmParameterException will be thrown. For example, a CertPathValidator that implements the PKIX algorithm validates CertPath objects of type X.509.

Parameters:

certPath - the CertPath to be validated

params - the algorithm parameters

Returns:

the result of the validation algorithm

Throws:

CertPathValidatorException - if the CertPath does not validate

InvalidAlgorithmParameterException - if the specified parameters or the type of the specified CertPath are inappropriate for this CertPathValidator
