Defines projection parameters with a list of fields to be included in the query results.
Extends: Array<string>
Description
The ProjectionParams class allows you to define projection parameters with a list of fields to be included in your query results.
Important points
- The parameters support two formats: dot and nested.
- The dot format is the standard way to define the included fields and subfields by using dot object notation. E.g. “field1,field2.field21,field2.field22.field221”.
- As an alternative, the nested format offers a more compact representation. E.g. “field1,field2(field21,field22(field221))".
Constructors
Creates a new instance of ProjectionParams and assigns its value.
public
ProjectionParams(AnyValueArray array)
- values: AnyValueArray - (optional) values used to initialize this object.
Instance methods
toString
Gets a string representation of the object. The result is a comma-separated list of projection fields “field1,field2.field21,field2.field22.field221”
public
String toString()
- returns: String - string representation of the object.
Static methods
fromValue
Converts a specified value into a ProjectionParams object.
See AnyValueArray.fromValue
public static
ProjectionParams fromValue(Object value)
- value: Object - value to be converted
- returns: ProjectionParams - newly created ProjectionParams object.
Examples
{
FilterParams filter = FilterParams.fromTuples("type", "Type1");
PagingParams paging = new PagingParams(0, 100);
ProjectionParams projection = ProjectionParams.fromString("field1,field2(field21,field22)")
myDataClient.getDataByFilter(filter, paging, projection);
