All Implemented Interfaces:

Serializable

public final class IlrBadContextException
extends RuntimeException

This exception is thrown when there is a mismatch between execution context classes.

In JRules, the class IlrRuleset represents a ruleset and the class IlrContext represents the context where a ruleset is executed. The IlrContext class can be instantiated directly or can be derived to include additional fields and methods. Since rules can refer to and use the fields and methods of the derived context class, the rules defined for a given context cannot be used by another context. This exception is thrown if the context is not the correct type.

Below is the list of methods that perform context type checking. These methods may throw an exception of class IlrBadContextException. See these methods for more details.
