Load()

template<typename ValueType>

void PARAM< ValueType >::Load ( JSON_SETTINGS *  aSettings, bool  aResetIfMissing = true  ) const

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.
