Interface CASession

All Superinterfaces:

java.rmi.Remote

All Known Implementing Classes:

Session, Session

public interface CASession

extends java.rmi.Remote

CASession is an interface representing a session with a computer algebra (CA) system. A CA system is typically accessed remotely, thus this interface is for use with RMI. This interface is roughly that outlined in the paper S. Linton and A. Solomon, OpenMath, IAMC and GAP (in proceedings of ISSAC 99/IAMC workshop)

Method Summary

javamath.server.cas.OMObject	evaluateOpenMath(javamath.server.cas.OMObject obj) Send an Openmath object to the computer algebra system and return an Openmath object as a result.
java.lang.String	getNativeError() Retrieves the error message generated by the last command sent to the compute engine.
java.lang.String	getNativeOutput() Retrieves the output of the last command sent to the compute engine.
java.lang.String	nativeEvaluate(java.lang.String input) Equivalent to sendNativeCommand composed with getNativeOutput
javamath.server.cas.OMObject	retrieveOpenMath(java.lang.String varname) Retrieve the object stored in variable varname in the compute engine as an OpenMath object.

Send an Openmath object to the computer algebra system and return an Openmath object as a result.

assignOpenMath

public void assignOpenMath(java.lang.String varname,
                           javamath.server.cas.OMObject obj)

                                 throws java.rmi.RemoteException

Retrieves the output of the last command sent to the compute engine.

getNativeError

public java.lang.String getNativeError()
                                throws java.rmi.RemoteException

Retrieves the error message generated by the last command sent to the compute engine.

closeSession

public void closeSession()
                  throws java.rmi.RemoteException
