Detailed Description

Advanced error object that wrap low-level system errors.

A BSystemError is a concrete advanced error object that is used to wrap tradition errors that are usually returned as a status_t. This type takes the system error, and adds an origin specifier.

Constructor & Destructor Documentation

BSystemError() [1/4]

BPrivate::Network::BSystemError::BSystemError	(	const char *	origin,
		status_t	error
	)

Create an object for error code with a specified origin.

Parameters

origin	A string representing where this error occured. As this object usually wraps around a lower level API call, this should usually be the call that the error code originated from.
error	The error code.

BSystemError() [2/4]

BPrivate::Network::BSystemError::BSystemError	(	BString	origin,
		status_t	error
	)

Create an object for error code with a specified origin.

Parameters

origin	A string representing where this error occured. As this object usually wraps around a lower level API call, this should usually be the call that the error code originated from.
error	The error code.

Member Function Documentation

DebugMessage()

BString BPrivate::Network::BSystemError::DebugMessage ( ) const

overridevirtual

Retrieve a debug message that contains all info in this error.

[Origin] Message of error (error code)

Exceptions

std::bad_alloc

In the future this method may throw this exception when the memory for the debug message cannot be allocated.

Returns

A BString object that contains the debug message.
