Class PuIntervalDescr

java.lang.Object

jv.object.PsObject

jvx.primitive.PuIntervalDescr

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, PsUpdateIf

public class PuIntervalDescr
extends PsObject

Interval used as one-dimensional domain with variable size and discretization. Info panel allows to adjust size and discretization of interval. An interval in R^1 is the segment [uMin,vMin] with numULines sample points in u-horizontal direction.

Since:

JavaView 3.50.002

Constructor Detail

PuIntervalDescr

public PuIntervalDescr()

Create a new domain descriptor of a planar rectangle and its discretization.

Note, currently the dimension of the rectangle must be 2.

Method Detail

init

public void init()

Initialize and reset data structure and all instance variables.

Overrides:

init in class PsObject

clone

public java.lang.Object clone()

Duplicate geometry by recursively cloning all instance variables except inspector panels and lists of registered listeners. The parent relationship is maintained only within this class but not to external classes.

Overrides:

clone in class PsObject

copy

public void copy(PsObject object)

Copy a geometry into this geometry.

Overrides:

copy in class PsObject

See Also:

PsObject.clone()

Version:

toString

public java.lang.String toString()

Create a multi-line string representation with detailed information about all instance variables.

Overrides:

toString in class PsObject

Version:

17.01.04, 1.00 created (kp)

update

public boolean update(java.lang.Object event)

Catch all events from integer and double instance variables.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PsObject

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false
