Detailed Description

Base class for coordinate information storage.

Library: ilvcharts

This class stores specific information related to a data coordinate (x, y, theta, or rho) that is represented by a given scale. It stores the minimum and maximum values for the coordinate that will be used to select the data to display. It also stores a pointer to an IlvCoordinateTransformer object that specifies a transformation that will be applied to this coordinate.

The minimum and maximum values for a coordinate that will be used to select the data to display can be specified in two ways:

By hand by the means of the IlvCoordinateInfo::setUserDataMin, IlvCoordinateInfo::setUserDataMax or IlvCoordinateInfo::setUserDataRange methods. In this case, the values set by the user will be used to select the data. This means that only the data within the specified interval for the coordinate will be displayed.
By automatic computation by calling the IlvCoordinateInfo::useAutoDataRange with IlTrue as a parameter. In this case, the minimum and maximum values for the coordinate are automatically computed from the data so that they include all the defined data. This means that all the data will be selected to be displayed.

The minimum and maximum values that are set by the user are returned by the IlvCoordinateInfo::getUserDataMin and IlvCoordinateInfo::getUserDataMax methods, respectively. If no values are specified by the user, the returned values are both equal to 0.

The minimum and maximum values that are automatically computed from the data are returned by the IlvCoordinateInfo::getAutoDataMin and IlvCoordinateInfo::getAutoDataMax methods, respectively.

The minimum and maximum values that are actually used to select the data to display are returned by the IlvCoordinateInfo::getDataMin and IlvCoordinateInfo::getDataMax methods. These values correspond to the values set by the user or to the automatically computed values if no values have been set by the user.

The values that are positioned at the minimum and maximum positions of the scale associated with the coordinate are obtained by the IlvCoordinateInfo::getMinPosData and IlvCoordinateInfo::getMaxPosData methods.

You can see an example on the figure below where two scales are represented: a normal scale and a cyclic scale. The values that are positioned at the minimum and maximum positions of both scales are 0 and 6 (see minPosData and maxPosData in the figure). The minimum and maximum values used to select the data are 0 and 6 for the normal scale, and 2 and 8 for the cyclic scale (see dataMin and dataMax in the figure).

A lock/unlock system is provided in order to share this object among the different objects that use it. The lock/unlock system ensures that the coordinate information object will not be deleted as long as an object needs it (see the IlvCoordinateInfo::lock and IlvCoordinateInfo::unLock methods for more details).

Constructor & Destructor Documentation

§ IlvCoordinateInfo() [1/4]

IlvCoordinateInfo::IlvCoordinateInfo	(	IlvCoordinateType	coordinateType,
		IlvCoordinateTransformer *	transfo = `0`
	)

Constructor.

Initializes a new IlvCoordinateInfo object for a given coordinate (x, y, theta, or rho). By default, the minimum and maximum values used to select the data to display and the values that will be positioned at the minimum and maximum positions of the associated scale are set to 0. Since no minimum and maximum values used to select the data to display are specified, the flag indicating that the minimum and maximum values are automatically computed from the data is set to IlTrue. At this point in time, these automatically computed values are equal to 0, since the data that will be displayed is not yet known.

Parameters

coordinateType	The type of the coordinate with which the current object is associated. This type is `IlvAbscissaCoordinate` if the current object is associated with the abscissa or `IlvOrdinateCoordinate` if it is associated with the ordinate.
transfo	The transformation that will be applied to the considered coordinate.

§ IlvCoordinateInfo() [2/4]

IlvCoordinateInfo::IlvCoordinateInfo	(	IlvCoordinateType	coordinateType,
		IlDouble	dataMin,
		IlDouble	dataMax,
		IlvCoordinateTransformer *	transfo = `0`
	)

Constructor.

Initializes a new IlvCoordinateInfo object for a given coordinate (x, y, theta, or rho). The parameters dataMin and dataMax correspond to the minimum and maximum values set by the user. The minimum and maximum values used to select the data to display are set to these values. The values that will be positioned at the minimum and maximum positions of the associated scale are set to the minimum and maximum values that will be used to select the data to display. Therefore, they are also set to dataMin and dataMax. The flag indicating that the minimum and maximum values are automatically computed from the data is set to IlFalse since the minimum and maximum values used to select the data to display are specified by hand.

Parameters

coordinateType	The type of the coordinate with which the current object is associated. This type is `IlvAbscissaCoordinate` if the current object is associated with the abscissa or `IlvOrdinateCoordinate` if it is associated with the ordinate.
dataMin	The minimum value of the coordinate used to select the data to display.
dataMax	The maximum value of the coordinate used to select the data to display.
transfo	The transformation that will be applied to the considered coordinate.

§ Load()

static IlvCoordinateInfo* IlvCoordinateInfo::Load ( IlvInputFile & file )

static

Reads a coordinate information object from a file.

Creates a coordinate information instance from the description stored in the file file. The object description must have been written with the IlvCoordinateInfo::save method.

Parameters

file	The file where the object description is stored.

Returns: A pointer to the created object.

§ lock()

void IlvCoordinateInfo::lock ( )

Locks the current IlvCoordinateInfo object.

Ensures that the current IlvCoordinateInfo object will not be destroyed before it is unlocked.
This method increments a reference count initially set to 0.

When you keep a pointer to an IlvCoordinateInfo object (because you store it in the field of an object or it is in a variable), you should lock it for the duration of its use so that it is not destroyed by some other object or component. When you do not need the IlvCoordinateInfo any more, you should release it with a call to unLock; if the lock you just removed was the last one, Rogue Wave Views will free the IlvCoordinateInfo.

§ Read()

static IlvCoordinateInfo* IlvCoordinateInfo::Read ( IlvInputFile & file )

static

Reads the attributes of a coordinate information object from a file.

Reads from a file the attributes specific to an object which have been written by the corresponding IlvCoordinateInfo::write method and creates a copy of this object. The Read method is called by the IlvCoordinateInfo::Load method. The IlvCoordinateInfo::Load method read the information indicating the type of the stored object before calling the Read method. Therefore, you should use the Read method directly only when you know the type of the stored object.

Parameters

file	The file where the object attributes are stored.

Returns: A pointer to the created object.

§ removeListener()

IlvCoordinateInfoListener* IlvCoordinateInfo::removeListener ( IlvCoordinateInfoListener * l )
