ReadOperator Class

Represents an operator that reads Feature elements from a DataSet.

Namespace: Carmenta.Engine
NuGet/Assembly: Carmenta.Engine.5.16.2.nupkg (in the CECore assembly)

Thread safety: Members defined in this class are, in general, not thread-safe. Show

Syntax

public class ReadOperator : Operator

Remarks

All layers that read data from a DataSet must have a ReadOperator first. If the DataSet contains visualization information then the ReadOperator connects a Visualizer to the features. Otherwise there must be a VisualizationOperator in the layer to get a presentation.

Example

// Create a ReadOperator, that reads all features from a MemoryDataSet
public static ReadOperator CreateReadOperatorWithMemoryDataSet()
{
    // Create a MemoryDataSet
    MemoryDataSet dataSet = new MemoryDataSet();

    // Create a ReadOperator, that reads from a MemoryDataSet
    return new ReadOperator(dataSet);
}
