Class ParamSet

  +--weblogic.common.ParamSet

public final class ParamSet

extends java.lang.Object

implements java.lang.Cloneable, java.io.Externalizable

A ParamSet object is used to set parameters for events and remote procedures. A ParamSet contains ParamValues, which are accessible by keyname and index position.

A ParamSet keyname with its corresponding ParamValue makes up the name/value pair used by events, event registrations, evaluators, and actions.

Conversions among the various datatypes are handled automatically in a "Java" way, i.e., the conversion can be accomplished either of these ways:

• With a cast. For example, for float --> int, you might use:

   float f = 1.2;
     int i = (int) f;

• By using some java.* method for the conversion. For example, you might use:

   boolean b = Boolean.booleanValue("t");

Illegal conversions (for example, int to boolean) throw a ParamSetException.
