Class AIMSMapFunctionality

java.lang.Object
  com.esri.adf.web.aims.data.AIMSMapFunctionality

All Implemented Interfaces:

GISFunctionality, MapFunctionality

public class AIMSMapFunctionality

extends java.lang.Object

implements MapFunctionality

The AIMSMapFunctionality maintains the reference to the Map object.

When initFunctionality(com.esri.adf.web.data.GISResource) method is called, the GET_SERVICE_INFO request is sent to the ArcIMS Server.

Calling exportImage(), the GET_IMAGE AXL request is sent to the ArcIMS Server.

ArcIMS Map Functionality can be added using JSF managed bean configuration as shown below,

 <managed-bean>
  <managed-bean-name>aimsMap</managed-bean-name>
  <managed-bean-class>com.esri.adf.web.aims.data.AIMSMapFunctionality</managed-bean-class>
   <managed-bean-scope>none</managed-bean-scope>

AIMSMapFunctionality

public AIMSMapFunctionality()

Method Detail

initFunctionality

public void initFunctionality(GISResource resource)

Description copied from interface: GISFunctionality

The initialization chores for the functionality must be performed in this method. This method is called by the resource when the functionality needs to be initialized. This happens either when the resource itself is being initialized or if users add this functionality to the resource using the GISResource.addFunctionality(String, GISFunctionality) method after the resource has already been initialized.

Classes which implement this method should maintain the resource as a class instance variable and return the same in the GISFunctionality.getResource() method. The functionality is ready for use only after this method has been called.

Specified by:

initFunctionality in interface GISFunctionality

Parameters:

resource - the GISResource that this functionality supports

See Also:

GISResource.init(WebContext)

destroyFunctionality

public void destroyFunctionality()

Description copied from interface: GISFunctionality

The cleanup chores (such as releasing held resources) for the functionality must be performed in this method. This method is called by the GISResource when the resource itself is being destroyed.

The functionality is no longer usable after this method has been called.

Specified by:

destroyFunctionality in interface GISFunctionality

See Also:

GISResource.destroy()

getResource

public GISResource getResource()

Description copied from interface: GISFunctionality

Returns the GISResource associated with this functionality.

The resource passed to GISFunctionality.initFunctionality(GISResource) is maintained as a class variable and is accessible through this method.

Specified by:

getResource in interface GISFunctionality

Returns:

the GISResource associated with this functionality

getCurrentExtent

public WebExtent getCurrentExtent()

Description copied from interface: MapFunctionality

Returns the current extent of this map.

Specified by:

getCurrentExtent in interface MapFunctionality

Returns:

the current WebExtent of this map

setCurrentExtent

public void setCurrentExtent(WebExtent newMapExtent)

Description copied from interface: MapFunctionality

Sets the current extent of this map.

Specified by:

setCurrentExtent in interface MapFunctionality

Parameters:

newMapExtent - the current WebExtent of this map

getFullExtent

public WebExtent getFullExtent()

Description copied from interface: MapFunctionality

Returns the full extent of this map.

Typically, this extent should be determined by the functionality when it is initialized.

Specified by:

getFullExtent in interface MapFunctionality

Returns:

the full WebExtent of this map

getInitialExtent

public WebExtent getInitialExtent()

Description copied from interface: MapFunctionality

Returns the initial extent of this map.

Typically, this extent should be determined by the functionality when it is initialized.

Specified by:

getInitialExtent in interface MapFunctionality

Returns:

the initial WebExtent of this map

isDisabled

public boolean isDisabled()

Description copied from interface: MapFunctionality

Returns true if this map functionality is disabled. If a map functionality is disabled, the WebMap will not call the MapFunctionality.exportImage() on that functionality while it is disabled.

A map functionality is typically disabled by unchecking the resource node in the Table of Contents control.

Specified by:

isDisabled in interface MapFunctionality

Returns:

true if this map functionality is disabled

setDisabled

public void setDisabled(boolean disabled)

Description copied from interface: MapFunctionality

If true, this map functionality is disabled. If a map functionality is disabled, the WebMap will not call the MapFunctionality.exportImage() on that functionality while it is disabled.

A map functionality is typically disabled by unchecking the resource node in the Table of Contents control.

Specified by:

setDisabled in interface MapFunctionality

Parameters:

disabled - true if this map functionality is disabled

getMapScale

public double getMapScale()

Description copied from interface: MapFunctionality

Returns the current scale of this map.

Specified by:

getMapScale in interface MapFunctionality

Returns:

the current scale of this map

exportImage

public java.io.InputStream exportImage()

Description copied from interface: MapFunctionality

Exports this map for the current extent. Implementations should ensure the following:

• The map should be exported in the spatial reference of the associated WebContext.
• If this is not the bottom-most map functionality referenced by the WebMap, the image should exported by setting its background color as the transparent color. The WebMap#isLastEnabledMapFunctionality(this) can be used to determine this condition.

The WebMap calls this method on all its map functionalities and eventually fuses all the exported maps before streaming it to the user.

Specified by:

exportImage in interface MapFunctionality

Returns:

a java.io.InputStream to the exported image

getMap

public com.esri.aims.mtier.model.map.Map getMap()

Returns the Map object.

public void setDPI(int dpi)

Sets the DPI(dots per square inch) for the output image.

Parameters:

dpi - the DPI for the output image

getDPI

public int getDPI()

Returns the DPI from the map functionality.

Returns:

the DPI from the map functionality

setLoadEnvelope

public void setLoadEnvelope(boolean loadEnvelope)

If true, loads the envelope information for all layers.

Parameters:

loadEnvelope - if true, loads the envelope information for all layers

isLoadEnvelope

public boolean isLoadEnvelope()

Returns true, if envelope information is available for all layers.

Returns:

true if the envelope information is available

setLoadRenderer

public void setLoadRenderer(boolean loadRenderer)

If true, loads the renderer information for all layers.

Parameters:

loadRenderer - if true, loads the renderer information for all layers

Returns:

true if the renderer information is available

setLoadFields

public void setLoadFields(boolean loadFields)

If true, loads the fields information for all layers.

If the associated resource includes the ArcIMS Query functionality, then this property should set to true in order to perform query.

Parameters:

loadFields - if true, loads the fields information for all layers

isLoadFields

public boolean isLoadFields()

Returns true, if fields information is available for all layers.

Returns:

true if the fields information is available

setLoadExtensions

public void setLoadExtensions(boolean loadExtensions)

If true, loads the extensions information for all layers.

If the associated resource includes the ArcIMS Geocode functionality, then this property should set to true in order to perform geocoding.

Parameters:

loadExtensions - if true, loads the extensions information for all layers

isLoadExtensions

public boolean isLoadExtensions()

Returns true, if extensions information is available for all layers.

Returns:

true if the extensions information is available

setDefaultDataFrame

public void setDefaultDataFrame(java.lang.String defaultDataFrame)

Sets the default data frame in which the map functionality should work with.

This property is valid only if the associated resource service type is ImageServerArcMap.

Parameters:

defaultDataFrame - the default dataframe name

getDefaultDataFrame

public java.lang.String getDefaultDataFrame()

Returns the default dataframe name.

Returns:
