Detailed Description

template<typename Value>
class PARAM_MAP< Value >

Represents a map of <std::string, Value>.

The key parameter has to be a string in JSON.

The key must be stored in UTF-8 format, so any translated strings or strings provided by the user as a key must be converted to UTF-8 at the site where they are placed in the underlying map that this PARAM_MAP points to.

Values must also be in UTF-8, but if you use wxString as the value type, this conversion will be done automatically by the to_json and from_json helpers defined in json_settings.cpp

Template Parameters
Valueis the value type of the map

template<typename Value>
PARAM_MAP< Value >::PARAM_MAP ( const std::string & aJsonPath,

Member Function Documentation

◆ ClearUnknownKeys()

bool PARAM_BASE::ClearUnknownKeys ( ) const
inlineinherited
Returns
true if keys should be cleared from source file rather than merged. Useful for things such as text variables that are semantically an array but stored as a map.

Definition at line 78 of file parameters.h.

References m_clearUnknownKeys.

◆ 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 72 of file parameters.h.

References m_path.

◆ Load()

template<typename Value>
void PARAM_MAP< Value >::Load ( const JSON_SETTINGS & aSettings,
bool aResetIfMissing = true ) const
inlineoverridevirtual

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

Parameters
aSettingsis the JSON_SETTINGS object to load from.
aResetIfMissingif true will set the parameter to its default value if load fails

Implements PARAM_BASE.

Definition at line 747 of file parameters.h.

References JSON_SETTINGS::GetJson(), m_default, PARAM_BASE::m_path, m_ptr, and PARAM_BASE::m_readOnly.

◆ MatchesFile()

template<typename Value>
bool PARAM_MAP< Value >::MatchesFile ( const JSON_SETTINGS & aSettings) const
inlineoverridevirtual

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

Parameters
aSettingsis a JSON_SETTINGS to check the JSON file contents of
Returns
true if the parameter in memory matches its value in the file

Implements PARAM_BASE.

Definition at line 781 of file parameters.h.

◆ SetDefault()

template<typename Value>
virtual void PARAM_MAP< Value >::SetDefault ( )
inlineoverridevirtual

Implements PARAM_BASE.

Definition at line 776 of file parameters.h.

References m_default, and m_ptr.

◆ Store()

template<typename Value>
void PARAM_MAP< Value >::Store ( JSON_SETTINGS * aSettings) const
inlineoverridevirtual

Stores the value of this parameter to the given JSON_SETTINGS object.

Parameters
aSettingsis the JSON_SETTINGS object to store into.

Implements PARAM_BASE.
