Class CertPathBuilderSpi

java.lang.Object
java.security.cert.CertPathBuilderSpi
public abstract class CertPathBuilderSpi extends Object
The Service Provider Interface (SPI) for the CertPathBuilder class. All CertPathBuilder implementations must include a class (the SPI class) that extends this class (CertPathBuilderSpi) and implements all of its methods. In general, instances of this class should only be accessed through the CertPathBuilder 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 CertPathBuilderSpi instance concurrently should synchronize amongst themselves and provide the necessary locking before calling the wrapping CertPathBuilder object.

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

    • engineBuild

      public abstract CertPathBuilderResult engineBuild​(CertPathParameters params) throws CertPathBuilderException, InvalidAlgorithmParameterException
      Attempts to build a certification path using the specified algorithm parameter set.
      Parameters:
      params - the algorithm parameters
      Returns:
      the result of the build algorithm
      Throws:
      CertPathBuilderException - if the builder is unable to construct a certification path that satisfies the specified parameters
      InvalidAlgorithmParameterException - if the specified parameters are inappropriate for this CertPathBuilder

    • engineGetRevocationChecker

      public CertPathChecker engineGetRevocationChecker()
      Returns a CertPathChecker that this implementation uses to check the revocation status of certificates. A PKIX implementation returns objects of type PKIXRevocationChecker.

      The primary purpose of this method is to allow callers to specify additional input parameters and options specific to revocation checking. See the class description of CertPathBuilder for an example.

      This method was added to version 1.8 of the Java Platform Standard Edition. In order to maintain backwards compatibility with existing service providers, this method cannot be abstract and by default throws an UnsupportedOperationException.

      Returns:
      a CertPathChecker that this implementation uses to check the revocation status of certificates
      Throws:
      UnsupportedOperationException - if this method is not supported
