public abstract class CertPathBuilderSpi extends Object
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.

CertPathBuilder
public CertPathCheckerengineGetRevocationChecker()
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.
