public final Object getParameter( String param ) throws InvalidParameterException
Parameters
- param
- the string name of the parameter.
Returns
the object that represents the parameter value, or null if
there is none.
Description
Gets the value of the specified algorithm parameter. This method
supplies a general-purpose mechanism through which it is possible to
get the various parameters of this object. A parameter may be any
settable parameter for the algorithm, such as a parameter size, or
a source of random bits for signature generation (if appropriate),
or an indication of whether or not to perform a specific but optional
computation. A uniform algorithm-specific naming scheme for each
parameter is desirable but left unspecified at this time.
Exceptions
InvalidParameterException
if param is an invalid
parameter for this engine, or another exception occurs while
trying to get this parameter.
