This class acts as a factory for trust managers based on a
source of trust material. Each trust manager manages a specific
type of trust material for use by secure sockets. The trust
material is based on a KeyStore and/or provider specific sources.

Deprecated:As of JDK 1.4, this implementation-specific class was replaced by TrustManagerFactory.
