◆ base64_decode() [1/2]

template<typename InsertIterator >

void ome::common::base64_decode	(	std::string	base64,
		InsertIterator	dest
	)

Decode a Base64-encoded string.

Newlines and other whitespace breaking up the input are permitted.

Parameters

base64	the Base64-encoded string.
dest	the insert iterator for the destination

Exceptions

std::runtime_error on invalid input.

Referenced by base64_decode().

Here is the caller graph for this function:

◆ base64_decode() [2/2]

template<typename Container >

Container ome::common::base64_decode ( const std::string & base64 )

Decode a Base64-encoded string into a container.

Newlines and other whitespace breaking up the input are permitted.

Parameters

base64 the Base64-encoded string.

Returns: a container filled with the decoded bytes.

Exceptions

std::runtime_error on invalid input.

References base64_decode().

◆ base64_encode()

template<typename Iterator >

std::string ome::common::base64_encode	(	Iterator	begin,
		Iterator	end,
		uint8_t	linebreak = `76`
	)

Base64-encode a range of bytes.

The iterators may be of any uint8_t iterator type, for example a range in a container, raw pointers or any other compatible type.

Parameters

begin	the start of the byte range.
end	the end of the byte range.
linebreak	the position at which to break a line; zero to disable line breaks.

Returns: a Base64-encoded string.

◆ createLogger()

Logger ome::common::createLogger ( const std::string & className )

inline

Create a message logger for a class.

Parameters

className the class name owning the logger.

Returns: a message logger.

References getLogLevel(), and setLogLevel().

◆ getLogLevel()

logging::trivial::severity_level ome::common::getLogLevel ( )

Get global logging level.

Returns: the log severity.

Referenced by createLogger().

Here is the caller graph for this function:

◆ ltrim()

std::string ome::common::ltrim ( const std::string & str )

inline

Trim leading whitespace from a string.

Space, newline, carriage return and horizontal and vertical tabs are removed from the left-hand side of the string.

Parameters

str	the string to trim.

Returns: the left-trimmed string.

◆ make_relative()

boost::filesystem::path ome::common::make_relative	(	boost::filesystem::path	from,
		boost::filesystem::path	to
	)

inline

Make a relative path.

Parameters

from	the start (reference) path.
to	the end path (to make relative to the start path).

Returns: the relative path.

◆ module_runtime_path()

const boost::filesystem::path & ome::common::module_runtime_path ( const std::string & dtype )

Get the runtime installation prefix path for a module.

This is intended primarily for internal use, to allow discovery of the location of datafiles, loadable modules, etc. However, it may be freely used by additional components, both OME and third-party, to register paths.

Parameters

dtype the directory type to query.

Returns: the installation prefix path.

Exceptions

a	`std::runtime_error` if the path could not be determined.

References ome::common::Module::realpath.

◆ operator!=() [1/3]

bool ome::common::operator!=	(	const boolean &	lhs,
		bool	rhs
	)

inline

Compare boolean with bool for inequality.

Parameters

lhs	the first value to compare.
rhs	the second value to compare.

Returns: true if not equal, false if equal.

◆ operator!=() [2/3]

bool ome::common::operator!=	(	bool	lhs,
		const boolean &	rhs
	)

inline

Compare bool with boolean for inequality.

Parameters

lhs	the first value to compare.
rhs	the second value to compare.

Returns: true if not equal, false if equal.

◆ operator!=() [3/3]

bool ome::common::operator!=	(	const boolean &	lhs,
		const boolean &	rhs
	)

inline

Compare bool with boolean for inequality.

Parameters

lhs	the first value to compare.
rhs	the second value to compare.

Returns: true if not equal, false if equal.

◆ operator<<()

template<class charT , class traits >

std::basic_ostream<charT,traits>& ome::common::operator<<	(	std::basic_ostream< charT, traits > &	os,
		const boolean &	rhs
	)

inline

Output boolean to output stream.

Parameters

os	the output stream.
rhs	the boolean to output.

Returns: the output stream.

◆ operator==() [1/3]

bool ome::common::operator==	(	const boolean &	lhs,
		bool	rhs
	)

inline

Compare boolean with bool for equality.

Parameters

lhs	the first value to compare.
rhs	the second value to compare.

Returns: true if equal, false if not equal.

◆ operator==() [2/3]

bool ome::common::operator==	(	bool	lhs,
		const boolean &	rhs
	)

inline

Compare bool with boolean for equality.

Parameters

lhs	the first value to compare.
rhs	the second value to compare.

Returns: true if equal, false if not equal.

◆ operator==() [3/3]

bool ome::common::operator==	(	const boolean &	lhs,
		const boolean &	rhs
	)

inline

Compare boolean with boolean for equality.

Parameters

lhs	the first value to compare.
rhs	the second value to compare.

Returns: true if equal, false if not equal.

◆ operator>>()

template<class charT , class traits >

std::basic_istream<charT,traits>& ome::common::operator>>	(	std::basic_istream< charT, traits > &	is,
		boolean &	rhs
	)

inline

Set boolean from input stream.

Parameters

is	the input stream.
rhs	the boolean to set.

Returns: the input stream.

◆ register_module_paths()

void ome::common::register_module_paths ( )

Register OME-Common module paths.

This function forces path registration.

Note: This is a hack to allow static linking to work on Windows; without this, the module object is omitted and the paths aren't automatically registered. This will no longer be required once it is built as a DLL. Its only purpose is to force object inclusion when static linking, and ensure that the registration happens independently of object static construction order to allow use prior to main() entry. You should not use this.

◆ rtrim()

std::string ome::common::rtrim ( const std::string & str )

inline

Trim trailing whitespace from a string.

Space, newline, carriage return and horizontal and vertical tabs are removed from the right-hand side of the string.

Parameters

str	the string to trim.

Returns: the right-trimmed string.

◆ setLogLevel()

void ome::common::setLogLevel ( logging::trivial::severity_level severity )

Set global logging level.

Log messages will be filtered such that messages with a priority greater or equal to the specified severity will be logged; messages with a lower priority will be discarded.

If using Boost.Log for logging, this is used to set the logging core filter.

Parameters

severity the log severity.

Referenced by createLogger().

Here is the caller graph for this function:

◆ trim()

std::string ome::common::trim ( const std::string & str )

inline

Trim leading and trailing whitespace from a string.

Space, newline, carriage return and horizontal and vertical tabs are removed from the left- and right-hand sides of the string.

Parameters

str	the string to trim.

Returns: the trimmed string.
