Class CertPathBuilderSpi

java.lang.Object
  |
  +--java.security.cert.CertPathBuilderSpi

public abstract class CertPathBuilderSpi

extends Object

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 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
