A specification of CertStore
parameters.
The purpose of this interface is to group (and provide type safety for)
all CertStore
parameter specifications. All
CertStore
parameter specifications must implement this
interface.
Typically, a CertStoreParameters
object is passed as a parameter
to one of the CertStore.getInstance
methods.
The getInstance
method returns a CertStore
that
is used for retrieving Certificate
s and CRL
s. The
CertStore
that is returned is initialized with the specified
parameters. The type of parameters needed may vary between different types
of CertStore
s.
Public Methods
public abstract Object clone ()
Makes a copy of this CertStoreParameters
.
The precise meaning of "copy" may depend on the class of
the CertStoreParameters
object. A typical implementation
performs a "deep copy" of this object, but this is not an absolute
requirement. Some implementations may perform a "shallow copy" of some
or all of the fields of this object.
Note that the CertStore.getInstance
methods make a copy
of the specified CertStoreParameters
. A deep copy
implementation of clone
is safer and more robust, as it
prevents the caller from corrupting a shared CertStore
by
subsequently modifying the contents of its initialization parameters.
However, a shallow copy implementation of clone
is more
appropriate for applications that need to hold a reference to a
parameter contained in the CertStoreParameters
. For example,
a shallow copy clone allows an application to release the resources of
a particular CertStore
initialization parameter immediately,
rather than waiting for the garbage collection mechanism. This should
be done with the utmost care, since the CertStore
may still
be in use by other threads.
Each subclass should state the precise behavior of this method so that users and developers know what to expect.
