Class LayerTimeInfo

java.lang.Object
com.esri.arcgisruntime.arcgisservices.LayerTimeInfo
public final class LayerTimeInfo extends Object
Metadata about a Layer or Sublayers support for time. It contains various information needed to be able to perform time based queries such as the time fields, the native time reference and the time extent.

  • Method Details

    • getEndTimeField

      public String getEndTimeField()
      Gets the name of the field that contains end time for each feature in the layer. This is available for feature data that has a start and end time stored in two separate fields, where a feature's time is valid for a duration between the start time and the end time.
      Returns:
      the end time field name if time is stored in two fields, otherwise null.
      Since:
      100.0.0

    • hasLiveData

      public boolean hasLiveData()
      Indicates whether the service has live data or not. If true, export and identify operations will default the TimeExtent to startTime = (current server time - time interval), endTime = current server time.
      Returns:
      true if the service has live data, false otherwise.

      100.0.0

    • getStartTimeField

      public String getStartTimeField()
      Gets the name of the field that contains the start time for each feature in the layer. This is available for feature data that has time stored in either a single field where a feature's time is valid for an instant in time, or in two fields where a feature's time is valid for a duration between the start time and the end time.
      Returns:
      the start time field name

    • getInterval

      public TimeValue getInterval()
      Gets the time interval of the data in the layer. The time interval can be used as a time slider's step size.
      Returns:
      the time interval
      Since:
      100.3.0

    • getTrackIdField

      public String getTrackIdField()
      Gets the field name that defines the track ID. Values in the track ID field uniquely identify individual objects to allow observations of the same object at different times to be represented by different features in the layer.
      Returns:
      the track id field name

    • getTimeReference

      public TimeReference getTimeReference()
      Gets information about the time reference used for time values in the layer.
      Returns:
      the time reference
      Since:
      100.0.0

    • getTimeExtent

      public TimeExtent getTimeExtent()
      Gets the time extent that is inclusive of all the data in the layer.
      Returns:
      the time extent, or null if the service is not time aware
