Detailed Description

The type that is used when the GenericException policy is in effect or for exceptions epresenting framework exceptions that are not based on Java exceptions.

Sometimes, it is desirable to not throw typed exceptions, but to just have one generic exception type that is used for all types of exceptional events. This is the type that is used under those conditions.

Constructor & Destructor Documentation

◆ xmog_exception_impl() [1/3]

xmog_exception_impl::xmog_exception_impl	(	int	error_code,
		const char *	msg = `NULL`
	)

Creates a new exception instance with the given error code and optional error message.

This constructor is used for framework exceptions that are not "backed" by and underlying Java exception. An example of a framework exception might be the framework's inability to load a JVM.

Parameters

error_code	the error condition represented by this instance.
msg	the error message represented by this instance. May be `NULL`.

◆ xmog_exception_impl() [2/3]

xmog_exception_impl::xmog_exception_impl	(	int	error_code,
		const XMOG_WCHAR *	msg
	)

Creates a new exception instance with the given error code and error message.

This constructor is used for framework exceptions that are not "backed" by and underlying Java exception. An example of a framework exception might be the framework's inability to load a JVM.

Parameters

error_code	the error condition represented by this instance.
msg	the error message represented by this instance.

◆ xmog_exception_impl() [3/3]

xmog_exception_impl::xmog_exception_impl	(	int	error_code,
		jthrowable	t,
		xmog_flags	flags = `xmog_base::GLOBAL`
	)

Creates a new exception instance with the given error code and a Java exception instance.

This constructor is used for exceptions that are "backed" by a Java exception when the GenericException policy is in effect.

Parameters

error_code	the error condition represented by this instance.
t	the reference to the Java exception that was thrown.
flags	the type of Java reference.

Member Function Documentation

◆ get_message_chars()

virtual char* xmog_exception_impl::get_message_chars	(	xmog_localenv *	env = `NULL`,
		xmog_base *	enc = `NULL`
	)

virtual

Returns the error message for this instance.

The caller is responsible for cleaning up the returned string by calling xmog_util::free() or xmog_util::setString().

Parameters

env	the local call environment. May be `NULL`.
enc	the optional encoding to be used. Use one of the encodings in the xmog_java_string class.

Returns: the exception message, owned by the caller.

Reimplemented from xmog_exception.

◆ get_message_u16()

virtual unsigned short* xmog_exception_impl::get_message_u16 ( xmog_localenv * env = NULL )

virtual

Returns the error message for this instance.

The caller is responsible for cleaning up the returned string by calling xmog_util::free() or xmog_util::setString().

Parameters

env	the local call environment. May be `NULL`.

Returns: the exception message, owned by the caller.

Reimplemented from xmog_exception.
