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.

Public Methods
public abstract CertPathBuilderResult engineBuild (CertPathParameters params)
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
|
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 |
