DrawCore(IEnumerable<Feature>,GeoCanvas,Collection<SimpleCandidate>,Collection<SimpleCandidate>)

• This method draws the features on the canvas you provided.

• This overridden method is called from the concrete public method Draw. In this method, we take the features you passed in and draw them on the canvas you provided. Each style (based on its properties) may draw each feature differently. When overriding this method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. In many of the styles, we add properties to allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection.

• Type:Void
• Description:None

• features
  • Type:IEnumerable<Feature>
  • Description:This parameter represents the features you want to draw on the canvas.

• canvas
  • Type:GeoCanvas
  • Description:This parameter represents the canvas you want to draw the features on.

• labelsInThisLayer
  • Type:Collection<SimpleCandidate>
  • Description:The labels will be drawn in the current layer only.

• labelsInAllLayers
  • Type:Collection<SimpleCandidate>
  • Description:The labels will be drawn in all layers.

GetRequiredColumnNamesCore()

• This method returns the column data for each feature that is required for the style to properly draw.

• This abstract method is called from the concrete public method GetRequiredFieldNames. In this method, we return the column names that are required for the style to draw the feature properly. For example, if you have a style that colors areas blue when a certain column value is over 100, then you need to be sure you include that column name. This will ensure that the column data is returned to you in the feature when it is ready to draw. In many of the styles, we add properties to allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection.

• Type:Collection<String>
• Description:This method returns a collection of the column names that it needs.

ColumnName

This property gets and sets the column name used to match with the value specified in the items.

This is the column we use for matching.

• Type:String

ValueItems

This property gets the collection of ValueItems. Each item can have its own value to match.

You will want to add ValueItems to this collection. Each item can have its own style and matching string.
