ArConfigArg Class Reference

#include <ArConfigArg.h>

Detailed Description

Argument class for ArConfig.

Java and Python Wrappers: Swig cannot determine the correct constructor to use based on most target langugages types, so you must use subclasses defined for various types. Or, use the constructor that accepts functors for dealing with arguments. Also, Swig cannot use pointers to change variables, so you must create ArConfigArg objects, passing in default values, and retain references to those objects, in addition to passing them to ArConfig, and read new values from those objects if ArConfig changes; or pass functors to ArConfigArg instead of the initial value.

DESCRIPTION_HOLDER Argument that just holds a description.

STRING_HOLDER this one is for holding strings and reading them in and writing them out but not really letting them get sent anywhere (its for unknown config parameters (so they don't get lost if a feature is turned off)

SEPARATOR Empty argument that merely acts as a separator within a (large) section.

LAST_TYPE Last value in the enumeration.

ArConfigArg::ArConfigArg ( const char * name,

const char * description,

size_t maxStrLen

)

Constructor for making an argument of a string by pointer (see details).
This constructor can accept both an already-allocated string, or ArConfigArg can to the memory managment itself (reallocation and finally deletion). If maxStrLen is 0, then ArConfigArg will do its own memory management, with the contents of str copied as the initial value of the internally held string. Otherwise, str must point to an allocated string, with its size given by maxStrLen.
Java and Python Wrappers: Not available in Java or Python wrapper libraries. Use ArConfigArg_String subclass instead (which has no maxStrLen parameter in its constructor)

ArConfigArg::ArConfigArg ( const char * name,

ArRetFunctor1< bool, ArArgumentBuilder * > * setFunctor,

ArRetFunctor< const std::list< ArArgumentBuilder * > * > * getFunctor,

const char * description

)

Constructor for making an argument that has functors to handle things.
This constructor is for the functor type of argument, this is for cases that need to be complicated and have more than one argument per name... such as the sonar in a config file. Where this data needs to be used to construct internal data structures.

Parameters:

name Name of this argument

description Description of the purpose of this argument

setFunctor When an argument is read it is passed to this functor in an ArArgumentBuilder object. The functor should return false if there is an error or problem handling the argument, or true otherwise.

getFunctor Since configuration needs to be serialized to save files on disk or send data over the network etc., this functor will be called to get a list of strings to represent this argument and its value as text in the file etc.

Definition at line 206 of file ArConfigArg.cpp.

ArConfigArg::ArConfigArg ( Type type )

Constructs a new argument of the specified type.
This constructor is useful for creating separators within a config section.

Member Function Documentation

ArPriority::Priority ArConfigArg::getConfigPriority ( void ) const

Gets the priority (only used by ArConfig).
The priority of this argument when used in ArConfig.
Definition at line 725 of file ArConfigArg.cpp.

ArConfigArg::Type ArConfigArg::getType ( void ) const

Gets the type of the argument.

void ArConfigArg::setConfigPriority ( ArPriority::Priority priority )

Sets the priority (only used by ArConfig).
The priority of this argument when used in ArConfig.
Definition at line 734 of file ArConfigArg.cpp.

void ArConfigArg::setDisplayHint ( const char * hintText )

Sets the display hint for this arg.
The "display hint" is a text string that may be used by the client to improve the display of the argument. The following display hints are currently supported by MobileEyes and Mapper3.
For type STRING:

Choices:choice1(;;choice#i)*

For example, "Choices:North;;South;;East;;West"

MapItem:type|(Parent|SubType)|(Optional|Required)

For example, "MapItem:Dock|Parent|Optional"

Macro:taskClass1(;;taskClass#i)*|(Optional|Required)

For example, "Macro:Audio;;Camera;;Video|Optional"

Macro

When used with no qualifiers, there are no task class restrictions and the macro is optional

RobotFile:fileFilterNames|fileFilters

where:

fileFilterNames is a string that contains the complete displayable names for all of the file filters (e.g. Map files (*.map);;World files (*.wld)), or, empty if no filter needs to be applied, and

fileFilters is a string that contains just file extensions for each of the file filters (e.g. *.map;;*.wld"). The number and order of these filters must match that of the fileFilterNames parameter.

For example, "RobotFile:Map Files (*.map);;World Files (*.wld)|*.map;;*.wld"

For type INT:

Color

void ArConfigArg::setIgnoreBounds ( bool ignoreBounds = false )

Sets whether to ignore bounds or not (default is to not to.
This is for debugging and will prevent the bounds checking from happening, you shouldn't normally use it
