                        AutomationException

Description copied from interface: IEllipticArc

Copies the center and endpoints, angle of rotation, orientation and major/minor properties into the method parameters.

Supported Platforms

Windows, Solaris, Linux

Description

Given the EllipseStd value, returns the Center Point, From Point, To Point, Rotation Angle, Minor Axis to Major Axis Ratio, IsCounterClockwise value, and IsMinor value of the Elliptic Arc. If EllipseStd = TRUE, the From Point and To Point locations are relative offsets from the Center Point rather than the origin.

Remarks

These are the necessary inputs for PutCoords, except in special cases (half ellipse, full ellipse, Central Angle = 0, and Minor to Major Ratio = 0) where the ArcOrientation must know which of these cases exists to ensure that the desired Elliptic Arc is unambiguous. Any of the output parameters can be set to nil if that info is not desired.

-isCCW stands for "is counter clockwise"

Specified by:

Parameters:

ellipseStd - The ellipseStd (in)

center - A reference to a com.esri.arcgis.geometry.IPoint (in)

from - A reference to a com.esri.arcgis.geometry.IPoint (in)

               throws java.io.IOException,
                      AutomationException

Description copied from interface: IEllipticArc

Sets the center point and endpoints, angle of rotation, and orientation.

Supported Platforms

Windows, Solaris, Linux

Description

PutCoords creates an Elliptic Arc given the EllipseStd value, Center Point, From Point, To Point, Rotation Angle, Minor Axis to Major Axis Ratio, and the Arc Orientation. If EllipseStd = TRUE, the From Point and To Point locations are relative offsets from the Center Point rather than the origin.

Remarks

Unless the coordinates of the From and To Points are exactly on the defined Elliptic Arc, PutCoords is likely to create an invalid Elliptic Arc. Therefore, it is highly recommended that another Elliptic Arc creation method is used unless all of the necessary input parameters are exactly known.

Specified by:

putCoords in interface IEllipticArc

Parameters:

ellipseStd - The ellipseStd (in)

center - A reference to a com.esri.arcgis.geometry.IPoint (in)

from - A reference to a com.esri.arcgis.geometry.IPoint (in)

                               double[] minorMajorRatio)
                        throws java.io.IOException,
                               AutomationException

Description copied from interface: IEllipticArc

Returns the center point, starting angle, signed central angle, angle of rotation, ratio of the minor axis to the major axis, and axes.

Supported Platforms

Windows, Solaris, Linux

Description

Given the EllipseStd value, returns the Center Point, From Angle, Central Angle, Rotation Angle, semi-Major axis length, and Minor Axis to Major Axis Ratio for the Elliptic Arc. These are the same parameters used by PutCoordsByAngle to create the Elliptic Arc. If EllipseStd = TRUE, the From Angle is relative to the rotated semi-Major Axis rather than the X-Axis.

Remarks

Specified by:

queryCoordsByAngle in interface IEllipticArc

Parameters:

ellipseStd - The ellipseStd (in)

center - A reference to a com.esri.arcgis.geometry.IPoint (in)

fromAngle - The fromAngle (in/out: use single element array)

centralAngle - The centralAngle (in/out: use single element array)

putCoordsByAngle

public void putCoordsByAngle(boolean ellipseStd,
                             IPoint center,
                             double fromAngle,
                             double centralAngle,
                             double rotationAngle,
                             double semiMajor,
                             double minorMajorRatio)
                      throws java.io.IOException,
                             AutomationException

Description copied from interface: IEllipticArc

Sets the center point, starting angle, signed central angle, angle of rotation, ratio of the minor axis to the major axis, and axes.

Supported Platforms

Windows, Solaris, Linux

Description

Creates an Elliptic Arc given the EllipseStd value, Center Point, From Angle, Central Angle, Rotation Angle, semi-Major Axis length, and Minor Axis to Major Axis Ratio. If EllipseStd = TRUE, the From Angle is relative to the rotated semi-Major Axis rather than the X-Axis.

Remarks

This is the recommended way to create an arbitrary Elliptic Arc. However, due to numeric accuracy limitations of computers and trigonometric functions, the From and To Points may be very slightly offset from the expected coordinates. This is important to keep in mind when attempting to connect the endpoints to other segments.

Specified by:

putCoordsByAngle in interface IEllipticArc

Parameters:

ellipseStd - The ellipseStd (in)

center - A reference to a com.esri.arcgis.geometry.IPoint (in)

fromAngle - The fromAngle (in)

centralAngle - The centralAngle (in)

rotationAngle - The rotationAngle (in)

semiMajor - The semiMajor (in)

minorMajorRatio - The minorMajorRatio (in)

Throws:

AutomationException - If the ArcObject component throws an exception.

java.io.IOException - If there are interop problems.

getCenterPoint

public IPoint getCenterPoint()
                      throws java.io.IOException,
                             AutomationException

Description copied from interface: IEllipticArc

The center point of the arc.

Supported Platforms

Windows, Solaris, Linux

Description

The CenterPoint is the point where the Major Axis and Minor Axis of the EllipticArc intersect. The CenterPoint is the point from which all angles and distances are calculated to create the EllipticArc.

Remarks

Specified by:

getCenterPoint in interface IEllipticArc

Returns:

A reference to a com.esri.arcgis.geometry.IPoint

Throws:

AutomationException - If the ArcObject component throws an exception.

java.io.IOException - If there are interop problems.

queryCenterPoint

public void queryCenterPoint(IPoint center)
                      throws java.io.IOException,
                             AutomationException

Description copied from interface: IEllipticArc

Copies the center of this arc to the input point.

Supported Platforms

Windows, Solaris, Linux

Description

The CenterPoint is the point where the Major Axis and Minor Axis of the EllipticArc intersect. The CenterPoint is the point from which all angles and distances are calculated to create the EllipticArc. You must instantiate the Point before calling QueryCenterPoint. For example,

Dim pPoint as IPoint
Set pPoint = New Point

Remarks

The QueryCenterPoint method should be used in performance critical situations, where the center point of several arcs needs to be retrieved. The point is populated (not created) by the method. For example, this can be used to get the center point of several arcs in a loop. Creating the point only once outside the loop may improve performance for large number of arcs.

Specified by:

queryCenterPoint in interface IEllipticArc

Parameters:

center - A reference to a com.esri.arcgis.geometry.IPoint (in)

Throws:

AutomationException - If the ArcObject component throws an exception.

Description copied from interface: IEllipticArc

Indicates if this elliptic arc is oriented counter-clockwise from its 'from' point to its 'to' point.

Supported Platforms

Windows, Solaris, Linux

Specified by:

setIsCounterClockwise in interface IEllipticArc

Parameters:

isCCW - The isCCW (in)

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isMinor

public boolean isMinor()
                throws java.io.IOException,
                       AutomationException

Description copied from interface: IEllipticArc

Indicates whether the arc is a minor arc or a major arc.

Specified by:

Returns:

The isMinor

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setIsMinor

public void setIsMinor(boolean isMinor)
                throws java.io.IOException,
                       AutomationException

Description copied from interface: IEllipticArc

Indicates whether the arc is a minor arc or a major arc.

Supported Platforms

Windows, Solaris, Linux

Specified by:

Parameters:

isMinor - The isMinor (in)

Throws:

AutomationException - If the ArcObject component throws an exception.

java.io.IOException - If there are interop problems.

complement

public void complement()
                throws java.io.IOException,
                       AutomationException

Description copied from interface: IEllipticArc

Changes this ellipse into its complement; 'from' and 'to' points are unchanged.

Supported Platforms

Windows, Solaris, Linux

Description

The Complement of an EllipticArc is the EllipticArc between the ToPoint and the FromPoint of the original EllipticArc that creates a full ellipse when combined with the original EllipticArc. The Complement maintains the same FromPoint and ToPoint as the original EllipticArc, but has the different IsMinor and IsCounterClockwise values.

Remarks

Specified by:

complement in interface IEllipticArc

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isCircular

public boolean isCircular()
                   throws java.io.IOException,
                          AutomationException

Description copied from interface: IEllipticArc

Indicates if this elliptical arc is acutally circular (major and minor axes same length).

Specified by:

isCircular in interface IEllipticArc

Returns:

The isCircular

Throws:

AutomationException - If the ArcObject component throws an exception.

java.io.IOException - If there are interop problems.
