Detailed Description

_MRMFeaturePickerFile_ loads components and components groups parameters from a .csv file.

The structures defined in [MRMFeaturePicker](MRMFeaturePicker) are used.

It is required that columns `component_name` and `component_group_name` are present. Lines whose `component_name`'s or `component_group_name`'s value is an empty string, will be skipped. The class supports the absence of information within other columns.

A reduced example of the expected format (fewer columns are shown here): > component_name,component_group_name,TransitionGroupPicker:stop_after_feature,TransitionGroupPicker:PeakPickerMRM:sgolay_frame_length > arg-L.arg-L_1.Heavy,arg-L,2,15 > arg-L.arg-L_1.Light,arg-L,2,17 > orn.orn_1.Heavy,orn,3,21 > orn.orn_1.Light,orn,3,13

◆ extractParamsFromLine_()

bool extractParamsFromLine_ ( const StringList line,
const std::map< String, Size > &  headers,
MRMFeaturePicker::ComponentParams cp,
MRMFeaturePicker::ComponentGroupParams cgp 
) const
protected

Extracts the information from a `StringList` and saves it into the correct data structures.

Parameters
[in]lineThe line parsed from the input file
[in]headersA mapping from a given header to its value's position
[out]cpThe extracted component parameters
[out]cgpThe extracted component group parameters
Returns
Returns `false` if `component_name` or `component_group_name` are empty strings. Otherwise, it returns `true`.

◆ load()

void load ( const String filename,
std::vector< MRMFeaturePicker::ComponentParams > &  cp_list,
std::vector< MRMFeaturePicker::ComponentGroupParams > &  cgp_list 
)

Loads the file's data and saves it into vectors of `ComponentParams` and `ComponentGroupParams`.

The file is expected to contain at least two columns: `component_name` and `component_group_name`. Otherwise, an exception is thrown.

If a component group (identified by its name) is found multiple times, only the first one is saved.

Parameters
[in]filenamePath to the .csv input file
[out]cp_listComponent params are saved in this list
[out]cgp_listComponent Group params are saved in this list
Exceptions
Exception::MissingInformationIf the required columns are not found.
Exception::FileNotFoundIf input file is not found.

◆ setCastValue_()

void setCastValue_ ( const String key,
const String value,
Param params 
) const
protected

Helper method which takes care of converting the given value to the desired type, based on the header (here `key`) information.

Parameters
[in]keyThe header name with which the correct conversion is chosen
[in]valueThe value to be converted
[in,out]paramsThe object where the new value is saved
