public abstract class CertPathBuilderSpi extends Object
CertPathBuilderimplementations 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
CertPathBuilderclass. For details, see the Java Cryptography Architecture.
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
However, implementations of
CertPathBuilderSpi may still
encounter concurrency issues, since multiple threads each

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