Classes
class	Logger
	This class is used for regular logging. More...
class	NullLogger
	This class is used to disable logging, while still allowing for log messages to contain '<<' expressions. More...
class	SingleLogger
	This class prints a message only the first time it is created for the passed file_name and line_number. More...
class	ThrottledLogger
	This class prints a message only if the passed file_name and line_number has not printed a message in a certain amount of time. More...

Detailed Description

Internal logging implementation.

Should not be used by client code. Classes and variables are in an internal namespace to avoid polluting the Ion namespace.

Function Documentation

template<typename T >

T* ion::base::logging_internal::CheckNotNull	(	const char *	expr_string,
		T *	t
	)

Definition at line 354 of file logging.h.

References CheckNotNullCommon().

template<typename T >

T& ion::base::logging_internal::CheckNotNull	(	const char *	expr_string,
		T &	t
	)

Definition at line 359 of file logging.h.

References CheckNotNullCommon().

template<typename T >

const T& ion::base::logging_internal::CheckNotNull	(	const char *	expr_string,
		const T &	t
	)

This extra overload is needed to support non-const rvalues of non-pointer type.

For example, it enables the following use-case: CHECK_NOTNULL(make_scoped_ptr<T>(MakeT()));

Without this overload, the above code wouldn't compile.

Definition at line 371 of file logging.h.

References CheckNotNullCommon().

template<typename T >

T& ion::base::logging_internal::CheckNotNullCommon	(	const char *	expr_string,
		T &	t
	)

Helpers for CHECK_NOTNULL().

Two are necessary to support both raw pointers and smart pointers.
