The class Feature is the basic unit of which a FeatureSource is composed. A FeatureSource can be taken from a collection of Features stored in a ShapeFile, SQL Server 2008, Oracle, etc.A Feature is the basic data unit structure which is comprised of IDs that mark the identification of the Feature, a shape and a collection of data.

GetWellKnownBinary()

This method returns the well-known binary that represents the Feature.

This will return a copy of the well-known binary that represents the Feature.

This method returns the well known type that represents the Feature.

None

• Type:WellKnownType
• Description:This method returns the well known type that represents the Feature.

GetShape()

This method returns the shape class that represents the Feature.

This method allows you to get a shape class from a Feature. Because the Feature stores the geometry for itself in well-known binary, it may take some time to generate a shape class if the geometry is complex.

• Type:BaseShape
• Description:This method returns the shape class that represents the Feature.

GetWellKnownText()

This method returns the well-known text that represents the Feature.

This method allows you to get the well-known text from a Feature. Because the Feature stores the geometry for itself in well-known binary, it may take some time to generate the text if the geometry is complex.

None

• Type:RectangleShape
• Description:This method returns the bounding box of the Feature.

• returningColumnNames
  • Type:IEnumerable<String>
  • Description:This parameter represents the columnar data fields that you wish to include in the clone.

CloneDeep(ReturningColumnsType)

This method clones the entire structure, creating a totally separate copy.

This method will return a complete copy of the Feature. As this is a deep clone, there are no shared references between the source and the copy.

• Type:Feature
• Description:This method returns a clone of the entire structure, creating a totally separate copy.

• returningColumnNamesType
  • Type:ReturningColumnsType
  • Description:This parameter allows you to select a type from the ReturningColumnsType that you wish to return with.

IsValid()

This method returns the results of some simple validity tests on the Feature.

This method is used primarily to ensure that a Feature is valid. The reason is, since this is a structure, we cannot control the main constructor that allows you to create a Feature in an invalid state – that state being one with no well-known binary at its core. If you use the constructure set provided, then the state should always be valid. This is a property you may want to check before you work with a Feature.

• Type:Boolean
• Description:This method returns the results of some simple validity tests on the Feature.

Equals(Object)

This method compares two InternalFeatures to see if they are equal.

None

• Type:Boolean
• Description:This method compares two InternalFeatures to see if they are equal.

• obj
  • Type:Object
  • Description:The first Feature.

This method returns a semi-unique hash code for the Feature.

None

• Type:Int32
• Description:This method returns a semi-unique hash code for the Feature.

Id

This property gets the Id for the Feature.

The Id is a string that represents the unique identifier for this Feature. If the feature is returned from a FeatureSource, the Id will be the unique field descriptor used by the FeatureSource. For Shape Files this may be an integer, but for spatial databases the Id may be a GUID.

• Type:String

Tag

The tag of the Feature.

N/A

• Type:Object

ColumnValues

This property gets a dictionary of values to represent the column data related to this Feature.

This property holds the column data related to this Feature. You can find the values in the dictionary using the column name as the key. Most methods that query and return InternalFeatures allow you to specify which columns of data you want returned with the results. You can also freely add and modify the data, as it is simply an in-memory dictionary. Any values added, deleted or updated will have no effect unless the Feature is part of a transaction.

• Type:Dictionary<String,String>
