public class ISnappingEnvironmentProxy
extends com.esri.arcgis.interop.Dispatch
implements ISnappingEnvironment, Serializable

ISnappingEnvironment Interface

Remarks

ISnappingEnvironment is the primary interface for working with and managing the snapping environment at 10.0. Other snapping methods available at previous versions, notably the ArcMap editor’s snap environment (accessed from IEditor.SnapEnvironment) and the engine editor’s snapping environment (accessed via IEngineSnapEnvironment) still exist at ArcGIS 10.0. These are separate environments and developers should be aware of which snapping environment their tools are using. One of the main benefits of the new snapping environment is its availability to both ArcMap and ArcGIS Engine developers, and the capability to utilize snapping for all tools, not editing.

Remarks

The Enabled property determines whether the snapping environment is active. If enabled, tools that utilize the mouse movement will return valid ISnappingResult references. Because this is setting is shared across all tools and applications, it is not recommended that individual tools modify this setting.

Remarks

Use the esriSnappingType enumeration to define which snapping types should be evaluated when IPointSnapper.Snap is called. An individual snapping type can be specified, or a combination of snapping types may be used. The combination of snapping types is accomplished using a bit mask.

Snapping Types are evaluated in a fixed order defined below:

1. esriSnappingTypePoint
2. esriSnappingTypeIntersection
3. esriSnappingTypeEndpoint
4. esriSnappingTypeVertex
5. esriSnappingTypeMidpoint

                          AutomationException

The types of snapping tip to be displayed.

Remarks

The snapping tip type can contain the layer name of the feature layer that was snapped to, or the snapping type that was satisfied. The default is to show both the layer name and the snapping type as part of the snap tip.

Product Availability

Available with ArcGIS Engine.

Specified by:

getSnapTipType in interface ISnappingEnvironment

Returns:

A com.esri.arcgis.controls.esriSnappingTipType constant

Parameters:

options - A com.esri.arcgis.controls.esriSnappingTipType constant (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getSnapTipSymbol

public ITextSymbol getSnapTipSymbol()
                             throws IOException,
                                    AutomationException

The symbol that displays the snap tip.

Remarks

The SnapTipSymbol defines the textsymbol that is used to display information provided in the snap result’s description after a valid snap location was found. If ISnappingEnvironment.SnapTipType = 0 (no snap tip) this setting had no effect.

You have a number of options to customize the tip symbol, including advanced text capabilities provided by IFormattedTextSymbol to provide options for backgrounds, offsets, or right-to-left text capabilities.
The location of the tip is not customizable; the application will display the snap tip above and to the right of the snap location, unless at the extreme top or right bounds of the display.
SnapTipSymbol is an application-level setting.

Product Availability

Available with ArcGIS Engine.

Specified by:

getSnapTipSymbol in interface ISnappingEnvironment

Returns:

A reference to a com.esri.arcgis.display.ITextSymbol

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setSnapTipSymbolByRef

public void setSnapTipSymbolByRef(ITextSymbol symbol)
                           throws IOException,
                                  AutomationException

The symbol that displays the snap tip.

Product Availability

Available with ArcGIS Engine.

Specified by:

setSnapTipSymbolByRef in interface ISnappingEnvironment

Parameters:

symbol - A reference to a com.esri.arcgis.display.ITextSymbol (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isShowSnapTipBackground

public boolean isShowSnapTipBackground()
                                throws IOException,
                                       AutomationException

Toggles snap tip background on/off.

Remarks

The snapping tip uses XOR to display the snapping tip text. If you are snapping against an orthophoto or other imagery data source, the text may be difficult to see. By setting ShowTipBackground to true, a solid color is displayed so the snap tip text may be clearly seen.

This is an application-level setting, and is false by default.

Product Availability

Available with ArcGIS Engine.

Specified by:

isShowSnapTipBackground in interface ISnappingEnvironment

Returns:

The show

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

The color of the snapping symbol.

Remarks

Specifies the color of the snapping symbol displayed when a valid snap result was found. The default color is black. Changing the color to a high contrast value such as yellow or cyan is particularly useful in situations where you are working against imagery or other layers symbolized using grayscale. The snap symbol itself cannot be altered.

Parameters:

snapper - A reference to a com.esri.arcgis.controls.IPointSnapper (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isIgnoreIMSLayers

public boolean isIgnoreIMSLayers()
                          throws IOException,
                                 AutomationException

Ignores layers with slow response times.

Remarks

The IgnoreIMSLayers setting excludes IMS feature service layers from participating in the snapping cache. In most cases, the time required to build the snapping cache against IMS layers is not fast enough, so they are automatically excluded from the snapping cache. In certain situations, the IMS layer response time is reasonable (such as an IMS service on an intranet) setting this property to false will include these layers in the snapping cache. IgnoreIMSLayers is set to true by default.

The flag

Throws:

IOException - If there are interop problems.
