Class CertPathValidatorSpi

  extended by

public abstract class CertPathValidatorSpi
extends Object

The Service Provider Interface (SPI) for the 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.

Method Detail


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

certPath - the CertPath to be validated
params - the algorithm parameters
the result of the validation algorithm
CertPathValidatorException - if the CertPath does not validate
InvalidAlgorithmParameterException - if the specified parameters or the type of the specified CertPath are inappropriate for this CertPathValidator
