<P>
An InteractionSpec holds properties for driving an Interaction
with an EIS instance. An InteractionSpec is used by an Interaction
to execute the specified function on an underlying EIS.
<p>The CCI specification defines a set of standard properties for
an InteractionSpec. An InteractionSpec implementation is not
required to support a standard property if that property does
not apply to its underlying EIS.
<p>The InteractionSpec implementation class must provide getter and
setter methods for each of its supported properties. The getter and
setter methods convention should be based on the Java Beans design
pattern.
<p>The standard properties are as follows:
<UL>
<LI>FunctionName: name of an EIS function
<LI>InteractionVerb: mode of interaction with an EIS instance:
SYNC_SEND, SYNC_SEND_RECEIVE, SYNC_RECEIVE
<LI>ExecutionTimeout: the number of milliseconds an Interaction
will wait for an EIS to execute the specified function
</UL>
<p>The following standard properties are used to give hints to an
Interaction instance about the ResultSet requirements:
<UL>
<LI>FetchSize
<LI>FetchDirection
<LI>MaxFieldSize
<LI>ResultSetType
<LI>ResultSetConcurrency
</UL>
<p>A CCI implementation can provide additional properties beyond
that described in the InteractionSpec interface. Note that the
format and type of the additional properties is specific to an EIS
and is outside the scope of the CCI specification.
<p>It is required that the InteractionSpec interface be implemented
as a JavaBean for the toolability support. The properties on the
InteractionSpec implementation class should be defined through the
getter and setter methods pattern. An implementation class for
InteractionSpec interface is required to implement the
java.io.Serializable interface.
