FeatureSourceColumn¶

Namespace: ThinkGeo.Core

This class represents a column contained within a FeatureSource.

public class FeatureSourceColumn

Inheritance Object → FeatureSourceColumn

Remarks:

A FeatureSource is typically represented by a number of InternalFeatures and their column data. This column represents the characteristics of that data.

Properties¶

ColumnName¶

This property returns the name of the column.

public string ColumnName { get; set; }

Property Value¶

String

Remarks:

None

TypeName¶

This property returns the type name of the column.

public string TypeName { get; set; }

Property Value¶

String

Remarks:

This property is freeform and the type name is not tied to anything. It is wise to try and use familiar type names such as string, integer, date, etc., although it may not fit every different type of FeatureSource. We suggest thar you avoid using this property unless you know the types beforehand or simply want them for display purposes.

MaxLength¶

This property returns the maximum length of the column.

public int MaxLength { get; set; }

Property Value¶

Int32

Remarks:

The maximum length is user defined and not in any way enforced in our default FeatureSource implementation. It is mainly for display purposes or when dealing with a known Feature Source type.
