Member Function Documentation

GetJsonPath()

const std::string& PARAM_BASE::GetJsonPath ( ) const

inlineinherited

Returns

the path name of the parameter used to store it in the json file mainly useful in error messages

Definition at line 68 of file parameters.h.

{ return m_path; }

References PARAM_BASE::m_path.

Load()

void PARAM_WXSTRING_MAP::Load ( JSON_SETTINGS *  aSettings, bool  aResetIfMissing = true  ) const

overridevirtual

Loads the value of this parameter from JSON to the underlying storage.

Parameters

aSettings	is the JSON_SETTINGS object to load from.
aResetIfMissing	if true will set the parameter to its default value if load fails

Implements PARAM_BASE.

MatchesFile()

bool PARAM_WXSTRING_MAP::MatchesFile ( JSON_SETTINGS *  aSettings ) const

overridevirtual

Checks whether the parameter in memory matches the one in a given JSON file.

Parameters

aSettings

is a JSON_SETTINGS to check the JSON file contents of

Returns

true if the parameter in memory matches its value in the file
