This class uses a provider-based architecture.
To create a CertPathBuilder, call
one of the static getInstance methods, passing in the
algorithm name of the CertPathBuilder desired and optionally
the name of the provider desired.
Once a CertPathBuilder object has been created, certification
paths can be constructed by calling the build method and
passing it an algorithm-specific set of parameters. If successful, the
result (including the CertPath that was built) is returned
in an object that implements the CertPathBuilderResult
The static methods of this class are guaranteed to be thread-safe.
Multiple threads may concurrently invoke the static methods defined in
this class with no ill effects.
However, this is not true for the non-static methods defined by this class.
Unless otherwise documented by a specific provider, threads that need to
access a single CertPathBuilder instance concurrently should
synchronize amongst themselves and provide the necessary locking. Multiple
threads each manipulating a different CertPathBuilder instance
need not synchronize.
