MapleException

Exception class used in Java External Calling and Java Open Maple

 

Description

Method Summary

Description

• 

The com.maplesoft.externalcall.MapleException class is an Exception subclass that can be used in Java External Call (see define_external) and Java Open Maple (see Java Open Maple).

• 

In Java External Call, a Java method can throw a MapleException and Maple correctly converts the Java Exception into a Maple Exception.  The MapleException constructor allows for a limited number of arguments to be passed into Maple along with the Exception method. This functionality is similar to error.

• 

In Java Open Maple, most methods are declared to throw objects of type MapleException.

MapleException creates a new MapleException object from an existing MapleException object.  The new MapleException is identical to the e.

MapleException(String msg, Object o1, Object o2)

•
