Class CertPathBuilderSpi
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.

engineBuildpublic 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

engineGetRevocationCheckerReturns aCertPathCheckerthat this implementation uses to check the revocation status of certificates. A PKIX implementation returns objects of typePKIXRevocationChecker.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 CertPathBuilderfor 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 CertPathCheckerthat this implementation uses to check the revocation status of certificates
- Throws:
- UnsupportedOperationException- if this method is not supported
- Since:
- 1.8
