Functions

open override fun pushContext(newContext: ExecutionContext): PermissionError

open override fun toString(): String

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

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): PermissionError
