Detailed Description

Class containing the mutable state required by muParser.

Note: For performance reasons it is best to put all mutable state in a single object so that, for each function call, we only need to get thread-local data exactly once.

Constructor & Destructor Documentation

◆ ParserData() [1/2]

internal::FunctionParser::ParserData::ParserData ( )

default

Default constructor. Threads::ThreadLocalStorage requires that objects be either default- or copy-constructible: make sure we satisfy the first case by declaring it here.

◆ ParserData() [2/2]

internal::FunctionParser::ParserData::ParserData ( const ParserData & )

delete

std::is_copy_constructible gives the wrong answer for containers with non-copy constructible types (e.g., std::vector<std::unique_ptr<int>>)

for more information, see the documentation of Threads::ThreadLocalStorage. Hence, to avoid compilation failures, just delete the copy constructor completely.

Member Data Documentation

◆ vars

std::vector<double> internal::FunctionParser::ParserData::vars

Scratch array used to set independent variables (i.e., x, y, and t) before each muParser call.

Definition at line 149 of file mu_parser_internal.h.

◆ parsers

std::vector<std::unique_ptr<muParserBase> > internal::FunctionParser::ParserData::parsers

The actual muParser parser objects (hidden with PIMPL).
