Detailed Description

A class for working with formatted strings related to ModelParts.

Operations on strings with the following placeholders are supported:

• <model_part_name>
• <step>
• <time>
• <rank> See PlaceholderPattern for supported functionalities. Other placeholders can be added at compile time by tweaking the construction of the static member ModelPartPattern::mModelpartPlaceholderMap.

Member Function Documentation

Apply() [1/2]

std::string Apply

(

const ModelPart &

rModelPart

)

const

Substitute values from the specified ModelPart in the stored pattern.

Parameters

rModelPart

Model part to extract the values of placeholders from.

Note

rModelPart must store STEP and TIME.

Todo:

Add support for string formatting. Options are:

• snprintf from the C STL (security issues due to allowing the user to freely specify the format)
• fmt::format (requires fmtlib)
• std::format (==fmtlib adopted in the standard, requires C++20)
• boost::format (requires boost)

Apply() [2/2]

std::string Apply

Substitute values in the stored pattern.

Return a copy of the pattern that has its placeholders replaced with the corresponding values specified in the input map.

Parameters

rPlaceholderValueMap

string - string map associating values to placeholders {"palceholder" : "placeholder_value"}

GetPlaceholderMap()

static PlaceholderMap GetPlaceholderMap ( )
