Detailed Description

This class implements a config file-like interface over a memory-stored string list.

Use base class CConfigFileBase's methods read_{int,float,double,string,...}() and write() to actually read and write values.

		bool	failIfNotFound = `false`
	)		const

inlineinherited

Reads an "enum" value, where the value in the config file can be either a numerical value or the symbolic name, for example: In the code:

enum my_type_t { type_foo=0, type_bar };

In the config file:

    [section]
    type   = type_bar   // Use the symbolic name, or
    type   = 1          // use the numerical value (both lines will be
equivalent)

Which can be loaded with:

cfgfile.read_enum<my_type_t>("section","type", type_foo );

Note: For an enum type to work with this template it is required that it defines a specialization of mrpt::typemeta::TEnumType

This template method can be instantiated for matrices of the types: int, long, unsinged int, unsigned long, float, double, long double

Exceptions

std::exception If the key name is not found and "failIfNotFound" is true. Otherwise the "defaultValue" is returned.
