ThinkGeo.MapSuite.Core.ClassBreakStyle
Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.
This class represents a style based on class break values.

Parameters
DrawCore(IEnumerable<Feature>,GeoCanvas,Collection<SimpleCandidate>,Collection<SimpleCandidate>)
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.
Return Value
Type:Void
Description:None
Parameters
DrawSampleCore(GeoCanvas,DrawingRectangleF)
Return Value
Type:Void
Description:N/A
Parameters
GetRequiredColumnNamesCore()
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.

Parameters
Public Properties
ColumnName
This property gets and sets the column name in the FeatureSource where the data will be found for each feature.
You use this property to set the name of the column where the numeric data is stored for your features.
Return Value
BreakValueInclusion
This property gets and sets the value of if the break values are included in the break calculation.
Example: If you have a class break value set to 100 and the break value is included, then 100 is included for this break. If you set the value to excluded, then 100 would match with the break below 100 instead. Please see the ClassBreakStyle class remarks for a full description of how the ClassBreakStyle works.
Return Value
ClassBreaks
This property gets the collection of class breaks.
The class breaks determine which style to use, based on the break values. Please see the ClassBreakStyle class remarks for a full description of how the ClassBreakStyle works.
