public abstract Class CertPathBuilderSpi

extends Object
Class Inheritance
Known Direct Subclasses
sun.security.provider.certpath.SunCertPathBuilder
Imports
java.security.InvalidAlgorithmParameterException
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.

Method Detail

engineBuildback to summary
public abstract CertPathBuilderResult engineBuild(CertPathParameters params) throws CertPathBuilderException, InvalidAlgorithmParameterException

Attempts to build a certification path using the specified algorithm parameter set.

Parameters
params:CertPathParameters

the algorithm parameters

Returns:CertPathBuilderResult

the result of the build algorithm

Exceptions
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
engineGetRevocationCheckerback to summary
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:CertPathChecker

a CertPathChecker that this implementation uses to check the revocation status of certificates

Exceptions
UnsupportedOperationException:
if this method is not supported
