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.

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 parametersInvalidAlgorithmParameterException
- if the specified parameters are inappropriate for thisCertPathBuilder
-
engineGetRevocationChecker
Returns aCertPathChecker
that 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
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- Since:
- 1.8
