Member Function Documentation

allow_milps()

const bool cyclus::Env::allow_milps ( )

static

Returns

whether or not Cyclus should allow Mixed-Integer Linear Programs The default depends on a compile time option DEFAULT_ALLOW_MILPS, but may be specified at run time with the ALLOW_MILPS environment variable

Definition at line 164 of file env.cc.

cyclus_path()

const std::vector< std::string > cyclus::Env::cyclus_path ( )

static

Returns

the current value of the module environment variable CYCLUS_PATH

Definition at line 155 of file env.cc.

EnvDelimiter()

const std::string cyclus::Env::EnvDelimiter ( )

static

Returns

the correct environment variable delimiter based on the file system

Definition at line 82 of file env.cc.

FindModule() [1/2]

std::string cyclus::Env::FindModule ( std::string path )

static

Returns the full path to a module by searching through default install and CYCLUS_PATH directories.

You may optionally pass in the lib name itself without any frills. In this case, Python modules will also be searched.

Definition at line 179 of file env.cc.

FindModule() [2/2]

std::string cyclus::Env::FindModule ( std::string path, std::string lib )

static

Definition at line 183 of file env.cc.

GetBuildPath()

const std::string cyclus::Env::GetBuildPath ( )

static

The relative path to the root build directory (containing bin, lib, etc.)

Returns

the absolute path to the build directory

Definition at line 62 of file env.cc.

GetEnv()

std::string cyclus::Env::GetEnv ( std::string var )

static

Method to check the existence of and return an environment variable.

Parameters

var	is the variable to check and return

Definition at line 74 of file env.cc.

GetInstallPath()

const std::string cyclus::Env::GetInstallPath ( )

static

The relative path to the root install directory (containing bin, lib, etc.) This first checks the path of the cyclus executable itself and then tries the install directory given at run time.

Returns

the absolute path to the install directory

Definition at line 34 of file env.cc.

nuc_data()

const std::string cyclus::Env::nuc_data ( )

static

Returns

the current value of the data environment variable CYCLUS_NUC_DATA

Definition at line 98 of file env.cc.

PathBase()

std::string cyclus::Env::PathBase ( std::string path )

static

the path basis

Returns

path with the last item removed

Definition at line 25 of file env.cc.

PathDelimiter()

const std::string cyclus::Env::PathDelimiter ( )

static

Returns

the correct path delimiter based on the file system

Definition at line 90 of file env.cc.

rng_schema()

const std::string cyclus::Env::rng_schema ( bool flat = false )

static

Returns the current rng schema.

Uses CYCLUS_RNG_SCHEMA env var if set; otherwise uses the default install location. If using the default location, set flat=true for the default flat schema.

Definition at line 120 of file env.cc.

SetNucDataPath() [1/2]

static const void cyclus::Env::SetNucDataPath ( )

inlinestatic

Initializes the path to the cyclus_nuc_data.h5 file.

By default, it is assumed to be located in the path given by GetInstallPath()/share; however, paths in environment variable CYCLUS_NUC_DATA are checked first.

Definition at line 98 of file env.h.

SetNucDataPath() [2/2]

static const void cyclus::Env::SetNucDataPath ( std::string p )

inlinestatic

Initializes the path to the nuclear data library to p.

Definition at line 103 of file env.h.

SplitPath() [1/2]

static std::vector< std::string > cyclus::Env::SplitPath ( const std::string & s, char delim )

inlinestatic

splits a string of paths by a delimeter

Parameters

s	string of paths
delim	the delimeter character

Returns

the vector of split strings

Definition at line 45 of file env.h.

SplitPath() [2/2]

static void cyclus::Env::SplitPath ( const std::string & s, char delim, std::vector< std::string > & elems )

inlinestatic

splits a string of paths by a delimeter

Parameters

s	string of paths
delim	the delimeter character
elems	the vector of split strings

Definition at line 30 of file env.h.
