Exception.Cause.g_lib

lib ('libmint-exception')

Global library handle.

Exception.Cause.getCause

def (const self)

Returns the parent cause of this cause as an instance of Exception.Cause or none if this cause is the root cause.

Exception.Cause.getCauses

def (const self)

Returns the parent causes of this cause as an array of Exception.Cause starting from the root cause or none if this cause is the root cause.

Exception.Cause.getDepth

def (const self)

Returns the chaining depth of this cause as a number. The depth starts from 0 for the root cause and increase for each reraise.

Exception.Cause.getObject

def (const self)

Returns the exception object associated to this cause.

Exception.Cause.new

def (self, % object, depth)

def (const self)

Returns the error message.

Exception.cause

def (error)

Returns the cause exception for error as an insistance of Exception.Cause or none if error is not an object from the current exception chain or is the root cause. The error parameter can be an instance of Exception.Cause or the object that was raised.

Exception.causes

def (error)

Returns the causes exceptions for error as an array of Exception.Cause or none if error is not an object from the current exception chain. The causes list start from the root cause until the the error that caused error excluding it. The error parameter can be an instance of Exception.Cause or the object that was raised.

Exception.stacktrace

def ()

Returns the current exception's stacktrace as an array of StackFrame.

def (cause)

Returns the stacktrace for the cause exception object as an array of StackFrame or none if cause is not an object from the current exception chain. The cause parameter can be an instance of Exception.Cause or the object that was raised.
