setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Specified by:

Throws:

org.springframework.beans.BeansException

getStyleProvider

@Nullable
public Function<? super E,Style> getStyleProvider()

Returns:

style provider for a layer's geo-objects or null if not set

setStyleProvider

public void setStyleProvider(@Nullable
 Function<? super E,Style> styleProvider)

Sets the style provider for a layer's geo-objects, i.e. function that determines style for a corresponding entity's geometry that is displayed on a map.

Function should return fully described style for geo-object, otherwise, it may be not displayed. The provided style replaces existing styles in a feature.

For instance, source contains geo-objects for entity with Point datatype. For this datatype map renders MarkerFeature that has default style with icon. So to add, let's say, text under the icon, new style should contain the icon definition too. To achieve this we can create default marker style using MarkerStyle.createDefaultStyle() and edit it:

 source.setStyleProvider(shop ->
         MarkerStyle.createDefaultStyle()
                 .withText(new TextStyle()
                         .withText(shop.getName())
                         .withFont("15px sans-serif")
                         .withOffsetY(10)));
 

Parameters:

styleProvider - function that takes an entity as an argument and produces a Style for the entity's geometry

getSelectStyleProvider

@Nullable
public Function<? super E,List<Style>> getSelectStyleProvider()

Returns:

select style provider for a layer's geo-objects or null if not set

setSelectStyleProvider

public void setSelectStyleProvider(@Nullable
 Function<? super E,List<Style>> selectStyleProvider)

Sets select style provider for a layer's geo-objects. This function determines styles for a corresponding entity's geometry that is displayed on a map and selected by user. Pay attention that the function should return a list of styles that can be layered.

Note that select styles will be applied if getFeatureSelectEnabled() is enabled.

For instance, for Polygon geometry a function can return a style with slightly changed fill color with transparency and stroke with bright color:

 source.setSelectStyleProvider(entity ->
         List.of(new Style()
                 .withFill(new Fill("hsla(190, 61%, 51%, 0.4)"))
                 .withStroke(new Stroke()
                         .withWidth(6d)
                         .withColor("#24913C"))));
 

Parameters:

selectStyleProvider - function that takes an entity as an argument and produces a Style for the entity's geometry

getModifyStyleProvider

@Nullable
public Function<? super E,List<Style>> getModifyStyleProvider()

Returns:

modify style provider for a layer's geo-objects or null if not set

setModifyStyleProvider

public void setModifyStyleProvider(@Nullable
 Function<? super E,List<Style>> modifyStyleProvider)

Sets modify style provider for a layer's geo-objects. This function determines styles for generated vertex's point of a corresponding entity's geometry that is displayed on a map. The map generates a point for geometry's vertices to enable modification: adding new vertex, change vertex position.

Thus, the styles generated by the provider will be applied not to the entity's geometry, but to the generated vertex point of the entity's geometry.

Note that modify styles will be applied if getFeatureModifyEnabled() is enabled.

For instance, for Polygon geometry a function can return a style that colors a generated vertex to red:

 source.setModifyStyleProvider(entity ->
         List.of(new Style()
                 .withImage(new CircleStyle()
                         .withFill(new Fill("#FF1E00"))
                         .withRadius(6)
                         .withStroke(new Stroke()
                                 .withWidth(2d)
                                 .withColor("#04819E")))));
 

Parameters:

modifyStyleProvider - function that takes an entity as an argument and produces a Style for the entity's geometry

getOverlaps

public Boolean getOverlaps()

Specified by:

getOverlaps in interface AbstractVectorSource.HasOverlaps

Overrides:

getOverlaps in class AbstractVectorSource

Returns:

setOverlaps

public void setOverlaps(Boolean overlaps)

Description copied from interface: AbstractVectorSource.HasOverlaps

Sets whether source may have overlapping geometries. The default value is true.

Setting this to false (e.g. for sources with polygons that represent administrative boundaries) allows the renderer to optimise fill and stroke operations.

setOverlaps in interface AbstractVectorSource.HasOverlaps

Overrides:

setOverlaps in class AbstractVectorSource

Parameters:

overlaps - overlaps option

setUseSpatialIndex

public void setUseSpatialIndex(Boolean useSpatialIndex)

Description copied from interface: AbstractVectorSource.HasUseSpatialIndex

Specified by:

setUseSpatialIndex in interface AbstractVectorSource.HasUseSpatialIndex

Overrides:

setUseSpatialIndex in class AbstractVectorSource

Parameters:

useSpatialIndex - whether to use spatial index
