Public Interface of Distributions and Group Characteristic Lines/Maps

Unlike normal characteristic lines/maps, group characteristic lines/maps do not have a getAt method. Instead, the public interface is "split" between the distribution, which has a search method, and the group table, which has an interpolate method.

A group characteristic map requires sample points to be set for both distributions before the corresponding value can be interpolated.

The first table shows the public interface of distributions in ESDL.

Method	Returns	Usage
search(Xvalue)	void	Set the sample point of the distribution to Xvalue or calculates the interpolation factor for Xvalue.
getX(index)	<type of distribution>	Gets the axis point at index.
setX(index, value)	void	Sets the axis point at index to value.
getMaxSize()	udisc	Gets the max. size of the distribution.
getCurrentSize()	udisc	Gets the current size of the distribution.
setCurrentSize(size)	void	Gets the current size of the distribution to size.

The type of Xvalue and value must be the same as the type of the distribution; index and size must be non-negative integers.

The second table shows the public interface of group characteristic lines (1D group tables) in ESDL.

Method	Returns	Usage
interpolate()	<type of group table>	Get the value for the current sample points or interpolate it from the table.
getValue(index)	index	Gets the value at index.
setValue(index, value)	void	Sets the value at index to value.
getMaxSize()	udisc	Gets the max. size of the group table.
getCurrentSize()	udisc	Gets the current size of the group table.
setCurrentSize(size)	void	Sets the current size of the group table to size.

The type of Xvalue and value must be the same as the type of the distribution; index and size must be non-negative integers.

The third table shows the public interface of group characteristic maps (2D group tables) in ESDL.

Method	Returns	Usage
interpolate()	<type of group table>	Get the value for the current sample points or interpolate it from the table.
getValue(indexX, indexY)	index	Gets the value at indexX and indexY.
setValue(indexX, indexY, value)	void	Sets the value at indexX and indexY to value.
getMaxSizeX()	udisc	Gets the max. X size of the group table.
getMaxSizeY()	udisc	Gets the max. Y size of the group table.
getCurrentSizeX()	udisc	Gets the current X size of the group table.
getCurrentSizeY()	udisc	Gets the current Y size of the group table.
setCurrentSizeY(sizeX)	void	Sets the current X size of the group table to sizeX.
setCurrentSizeY(sizeY)	void	Sets the current Y size of the group table to sizeX.

The type of Xvalue, Yvalue and value must be the same as the type of the characteristic map; indexX , indexY, sizeX and sizeY must be non-negative integers.
