public abstract class IMiddleware

extends java.lang.Object

This class is never directly used by application programmers.

The class provides methods for middleware implementors and serves as a proxy between the low-level protocol handling routines (e.g RFC, HTTP/SOAP) and the API exposed to the programmer.

Method Detail

getPropertyInfo

public abstract java.lang.String[][] getPropertyInfo()

Returns information about the properties which are understood by the the implementation. Each element of the array should be a set of two Strings containg the name and description of a property. For example

  String pinfo[][] = {
     { "jco.middleware.name",    "sapjcorfc" },
     { "jco.middleware.version", "2.0" },
  };

value - the value of the property or null to remove a property

getName

public final java.lang.String getName()

Returns the name of the middleware layer

Returns:

the name of the middleware layer

getVersion

public final java.lang.String getVersion()
