◆ exception_ref

using xtd::exception::exception_ref = xtd::optional<std::reference_wrapper<const xtd::exception> >

Optional reference wrapper on std::exception.

Constructor & Destructor Documentation

◆ exception() [1/3]

xtd::exception::exception ( const xtd::diagnostics::stack_frame & stack_frame = xtd::diagnostics::stack_frame::current() )

explicit

Create a new instance of class exception.

Parameters

stack_frame (optional) Contains current stack frame about member name, file path and line number in the file where the exception is occurred. Typically xtd::diagnostics::stack_frame::current().

Remarks: Message is set with the default message associate to the exception.

◆ exception() [2/3]

xtd::exception::exception	(	const xtd::optional< xtd::string > &	message,
		const xtd::diagnostics::stack_frame &	stack_frame = `xtd::diagnostics::stack_frame::current()`
	)

explicit

Create a new instance of class exception.

Parameters

message	Message string associate to the exception.
stack_frame	(optional) Contains current stack frame about member name, file path and line number in the file where the exception is occurred. Typically xtd::diagnostics::stack_frame::current().

◆ exception() [3/3]

template<typename exception_t >

xtd::exception::exception	(	const xtd::optional< xtd::string > &	message,
		const exception_t &	inner_exception,
		const xtd::diagnostics::stack_frame &	stack_frame = `xtd::diagnostics::stack_frame::current()`
	)

inline

Create a new instance of class exception.

Parameters

message	Message string associate to the exception.
inner_exception	The exception that is the cause of the current exception.
stack_frame	(optional) Contains current stack frame about member name, file path and line number in the file where the exception is occurred. Typically xtd::diagnostics::stack_frame::current().

Member Function Documentation

◆ inner_exception()

virtual exception_ref xtd::exception::inner_exception ( ) const

virtualnoexcept

Gets the exception instance that caused the current exception.

Returns: An instance of exception that describes the error that caused the current exception. The inner_exception property returns the same value as was passed into the constructor, or a null reference if the inner exception value was not supplied to the constructor.

virtualnoexcept

Gets message associate to the exception.

Returns: A string represent a massage associate to the exception

Reimplemented in xtd::io::file_not_found_exception.

Examples: barrier.cpp, default_trace_listener.cpp, and file_info_move_to.cpp.

◆ source() [1/2]

virtual const xtd::string & xtd::exception::source ( ) const

virtualnoexcept

Gets the name of the application or the object that causes the error.

virtualnoexcept

Sets the name of the application or the object that causes the error.

Returns: The name of the application or the object that causes the error.

Returns: triue if stack trace enabled; otherwhise false.

◆ enable_stack_trace() [2/2]

static void xtd::exception::enable_stack_trace ( bool enable )

staticnoexcept

Sets if the generation of the stack trace is enabled. @paran enable triue if stack trace enabled; otherwhise false.
