com.pervasive.datarush.types.TypesNotComparableException

All Implemented Interfaces:

Serializable

public class TypesNotComparableException
extends DRException

Unchecked exception thrown when an attempt is made to compare two typed objects of incompatible types.

Exception chaining is used in two ways to provide additional details about the cause of a comparison error.

• In the case of a record type, the exception may contain a FieldTypesNotComparableException as the cause indicating which fields raised the error.
• Exceptions thrown from operators may contain another TypesNotComparableException. The wrapping exception contains more contextual information about the comparison performed.
