class RepresentationError(message: String? = null, cause: Throwable? = null, contexts: Array<ExecutionContext>, val limit: RepresentationError.Limit, extraData: Term? = null) : LogicError

A representation error occurs when an implementation limit has been breached

Parameters

message

the detail message string.

cause

the cause of this exception.

contexts

a stack of contexts localising the exception

limit

the name of the reached limit

extraData

the possible extra data to be carried with the error

Functions

open override fun pushContext(newContext: ExecutionContext): RepresentationError

open override fun toString(): String

open override fun updateContext(newContext: ExecutionContext, index: Int = 0): RepresentationError

Creates a new exception instance with the context with in position index updated to newContext. Subclasses should override this method and return the correct instance.

updateLastContext

open override fun updateLastContext(newContext: ExecutionContext): RepresentationError
