Method Detail

addListener

public void addListener(java.lang.String iidStr,
                        java.lang.Object theListener,
                        java.lang.Object theSource)
                 throws java.io.IOException

Description copied from class: Dispatch

Adds a Java object to be a listener for a specific kind of event generated by the COM object. when you wish to invoke method on the COM object using IDispatch (not using custom marshalling).

Overrides:

addListener in class ICurveProxy

Throws:

java.io.IOException

removeListener

public void removeListener(java.lang.String iidStr,
                           java.lang.Object theListener)
                    throws java.io.IOException

Description copied from class: Dispatch

Removes a Java object as a listener to events generated by a COM object. when you wish to invoke method on the COM object using IDispatch (not using custom marshalling).

Overrides:

removeListener in class ICurveProxy

Throws:

java.io.IOException

putCoords

public void putCoords(IPoint from,
                      IPoint to)
               throws java.io.IOException,
                      AutomationException

Description copied from interface: ILine

Sets this line's endpoints to be 'from' and 'to'.

Supported Platforms

Windows, Solaris, Linux

Description

The PutCoords method sets the From Point and To Point for a line object. If the From Point and To Point are identical, it creates a zero Length line with the same start and endpoint.

Remarks

Specified by:

putCoords in interface ILine

Parameters:

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

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

Throws:

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

AutomationException - If the ArcObject component throws an exception.

queryCoords

public void queryCoords(IPoint from,
                        IPoint to)
                 throws java.io.IOException,
                        AutomationException

Description copied from interface: ILine

Copies the endpoints of this line to 'from' and 'to'.

Supported Platforms

Windows, Solaris, Linux

Description

Queries the From and To Points of the Line. These are the only parameters necessary to create a well-defined line.

Remarks

Specified by:

queryCoords in interface ILine

Parameters:

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

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

Throws:

AutomationException - If the ArcObject component throws an exception.

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

getAngle

public double getAngle()
                throws java.io.IOException,
                       AutomationException

Description copied from interface: ILine

The angle between this line and the positive x-axis.

Supported Platforms

Windows, Solaris, Linux

Remarks

The following Visual Basic example gets the angle of a line and converts it to degrees :

dAngleDegree = (180 * pLine.Angle) / Pi

Where Pi = 4 * Atn(1)

Specified by:

getAngle in interface ILine

Returns:

The outAngle

Throws:

AutomationException - If the ArcObject component throws an exception.

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