Standard module methods
All `IMP` modules have a set of standard methods to help get information about the module and about files associated with the module.
std::string	get_module_version ()

std::string	get_module_name ()

Error checking and reporting
By default `IMP` performs a variety of runtime error checks. These can be controlled using the IMP::set_check_level function. Call IMP::set_check_level with IMP::NONE to disable all checks when you are performing your optimization as opposed to testing your code. Make sure you run your code with the level set to at least USAGE before running your final optimization to make sure that `IMP` is used correctly. Error handling is provided by IMP/base/exception.h, Use the `gdbinit` file provided in `tools` to automatically have `gdb` break when `IMP` errors are detected.
void	set_check_level (CheckLevel tf)
	Control runtime checks in the code. More...

CheckLevel	get_check_level ()
	Get the current audit mode.

void	handle_error (const char *msg)

Flags
These methods add support for shared command line flags to `IMP`. Programs that use this have access to flags declared in modules which allow users to do things like control log level and turn on and off profiling to see what is going on. These functions are python accessible. In C++, you can also use the AddFloatFlag, AddStringFlag, AddBoolFlag and AddIntFlag classes to add flags statically.

Logging
`IMP` provides tools for controlling the amount of log output produced and directing it to the terminal or a file. Only log messages tagged with a lower level than the current LogLevel are emitted. In addition to a global log level (get_log_level(), set_log_level()), each IMP::Object has an internal log level (IMP::Object::get_log_level(), IMP::Object::set_log_level()) which is used when executing code on that object. Logging is provided by IMP/base/log.h. People implementing IMP::Object classes should also see IMP_OBJECT_LOG() and IMP::SetLogState. All logging is disabled when `IMP` is built using `build='fast'`.
void	add_to_log (LogLevel level, std::string to_write)
	Write a string to the log, for python.

void	set_log_level (LogLevel l)
	Set the current global log level. More...

void	set_log_timer (bool tb)
	Set whether log messages are tagged with the current log time.

void	reset_log_timer ()
	Reset the log timer.

LogLevel	get_log_level ()
	Get the currently active global log level. More...

Create a progress bar in the terminal
void	set_progress_display (std::string description, unsigned int steps)

void	add_to_progress_display (unsigned int step=1)

Number of threads
Get and set the default number of threads to use in `IMP`.

Function Documentation

void IMP::base::add_bool_flag	(	std::string	name,
		std::string	description
	)

For python use. Default is always false.

void IMP::base::add_float_flag	(	std::string	name,
		double	default_value,
		std::string	description
	)

For python use.

void IMP::base::add_int_flag	(	std::string	name,
		size_t	default_value,
		std::string	description
	)

For python use.

void IMP::base::add_string_flag	(	std::string	name,
		std::string	default_value,
		std::string	description
	)

For python use.

void IMP::base::add_to_progress_display ( unsigned int step = 1 )

Set the current progress. When it equals the number of steps, the bar is done.

void IMP::base::clear_statistics ( )

Reset all the statistics for IMP.

TextOutput IMP::base::create_temporary_file	(	std::string	prefix = `"imp_temp"`,
		std::string	suffix = `""`
	)

Create a temporary file. The path can be extracted from the TextOutput.

If suffix is non-empty, there is some small chance of a collision on non-BSD systems as a unique temporary file is first created, and then a file with that suffix appended is created.

std::string IMP::base::create_temporary_file_name	(	std::string	prefix = `"imp_temp"`,
		std::string	suffix = `""`
	)

Create a temporary file.

If suffix is non-empty, there is some small chance of a collision on non-BSD systems as a unique temporary file is first created, and then a file with that suffix appended is created.

bool IMP::base::get_bool_flag ( std::string name )

For python use.

std::string IMP::base::get_data_path ( std::string file_name )

Each module has its own data directory, so be sure to use the version of this function in the correct module. To read the data file "data_library" that was placed in the data directory of module "mymodule", do something like

std::ifstream in(IMP::mymodule::get_data_path("data_library"));

This will ensure that the code works when IMP is installed or used via the setup_environment.sh script.

std::string IMP::base::get_example_path ( std::string file_name )

Each module has its own example directory, so be sure to use the version of this function in the correct module. For example to read the file example_protein.pdb located in the examples directory of the IMP::atom module, do

IMP::atom::read_pdb(IMP::atom::get_example_path("example_protein.pdb",

model));

This will ensure that the code works when IMP is installed or used via the setup_environment.sh script.

std::string IMP::base::get_executable_name ( )

Return the name of the current executable.

double IMP::base::get_float_flag ( std::string name )

For python use.

size_t IMP::base::get_int_flag ( std::string name )

For python use.

Strings IMP::base::get_live_object_names ( )

Return the names of all live objects, use this to check for memory leaks.

Objects IMP::base::get_live_objects ( )

Return the points to all live objects, use this to check for memory leaks.

LogLevel IMP::base::get_log_level ( )

Get the currently active global log level

Note: This may not always match the value passed to set_log_level() as objects can temporarily override the global level while they are evaluating.

See Also: set_log_level(); IMP::base::Object::set_log_level()

Definition at line 93 of file base/log.h.

unsigned int IMP::base::get_number_of_threads ( )

Get the current number of threads requested. The default is the number of cores/hardware threads in the machine if there is OpenMP support, or 1 otherwise.

boost::uint64_t IMP::base::get_random_seed ( )

Return the initial random seed.

std::string IMP::base::get_relative_path	(	std::string	base,
		std::string	relative
	)

Return a path to a file relative to another file. For example if base is path/to/config.file and relative is data/image0.jpg then the return value would be path/to/data/image0.jpg. This function should be used when processing configuration files so that the meaning of the configuration file does not change if current working directory changes.

std::string IMP::base::get_string_flag ( std::string name )

For python use.

std::string IMP::base::get_unique_name ( std::string templ )

Return a unique name produced from the string by replacing %1% with a sequential number.

void IMP::base::handle_error ( const char * msg )

This function is called whenever IMP detects an error. It can be useful to add a breakpoint in the function when using a debugger.

void IMP::base::handle_use_deprecated ( std::string message )

Break in this method in gdb to find deprecated uses at runtime.

template<class T >

bool IMP::base::isnan ( const T & a )

With certain compiler settings the compiler can optimize out a!=a (and certain intel chips had issues with it too).

Definition at line 24 of file base/math.h.

template<class O >

O* IMP::base::object_cast ( Object * o )

Up (or down) cast an IMP Object-derived class. If the cast does not succeed a ValueException will be thrown. Use a dynamic_cast if you prefer to have a nullptr returned.

Definition at line 24 of file base/object_cast.h.

void IMP::base::set_check_level ( CheckLevel tf )

The default level of checks is USAGE for release builds and USAGE_AND_INTERNAL for debug builds.

Definition at line 81 of file base/exception.h.

void IMP::base::set_deprecation_exceptions ( bool tf )

Toggle whether an exception is thrown when a deprecated method is used.

void IMP::base::set_deprecation_warnings ( bool tf )

If set to true (the default) a warning is printed every time a class marked as deprecated is used.

void IMP::base::set_log_level ( LogLevel l )

Set the current global log level

Note: may be overriden by set_log_level of specific objects that inherit from IMP::base::Object; this global method should not, currently, be used directly during kernel::Model::evaluate() calls.

See Also: get_log_level(); IMP::base::Object::set_log_level()

void IMP::base::set_log_target ( TextOutput l )

See TextOutput for options. Python users should use SetLogTarget instead.

void IMP::base::set_number_of_threads ( unsigned int n )

Set the current number of threads to a number greater or equal to 1. Setting it to 1 disables multithreaded evaluation.

void IMP::base::set_progress_display	(	std::string	description,
		unsigned int	steps
	)

Set up the progress bar with the passed description.

See IMP_PROGRESS_DISPLAY().
