                        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

generalize

public void generalize(double maxAllowableOffset)
                throws java.io.IOException,
                       AutomationException

Description copied from interface: IPath

Generalizes this path using the Douglas-Poiker algorithm.

Supported Platforms

Windows, Solaris, Linux

Description

Generalizes the Path into a generalized collection of Line segments. Generalize performs a Douglas-Poiker Generalization algorithm with a specified maximum offset tolerance given as input. For Line segments, the Generalized output is a subset of the original input vertices. For non-Linear segments, the Generalized output contains points along all parts of the curve, not necessarily only the vertices.

Remarks

For a path with non-linear segments, the output curve may contain more vertices than the input curve, but all output segments will be linear.

Specified by:

generalize in interface IPath

Parameters:

maxAllowableOffset - The maxAllowableOffset (in)

Throws:

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

AutomationException - If the ArcObject component throws an exception.

smooth

public void smooth(double maxAllowableOffset)
            throws java.io.IOException,
                   AutomationException

Description copied from interface: IPath

Converts this path into a smooth approximation of itself that contains only Bezier curve segments.

Supported Platforms

Windows, Solaris, Linux

Description

Converts the Path into a Path containing only BezierCurve segments. The created BezierCurve path is a Generalization of the original path that has a maximum deviation of maxDeviation from the original path. If maxDeviation = 0, all of the original vertices are maintained. At each vertex, the adjoining BezierCurves have complementary tangents which creates a continuous (smooth) transition between segments.

Remarks

Specified by:

smooth in interface IPath

Parameters:

maxAllowableOffset - The maxAllowableOffset (in)

Throws:

AutomationException - If the ArcObject component throws an exception.

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

smoothLocal

public void smoothLocal(int vertexIndex)
                 throws java.io.IOException,
                        AutomationException

Description copied from interface: IPath

Replaces up to four segments (two on each of the specified vertex index) with bezier curves.

Supported Platforms

Windows, Solaris, Linux

Description

Converts segments containing the indexed vertex into BezierCurves and performs a smoothing operation only at the two segments on either side of the input vertex. The created BezierCurves have complementary tangents at the indexed vertex.

Remarks

Specified by:

smoothLocal in interface IPath

Parameters:

vertexIndex - The vertexIndex (in)

Throws:

AutomationException - If the ArcObject component throws an exception.

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