All Known Implementing Classes:
ScalarChaserObject
public interface ScalarChaser
extends X3DChaserNode
ScalarChaser generates a series of single floating-point values that progressively change from initial value to destination value.

X3D node tooltip: (X3D version 3.2 or later) [X3DChaserNode] ScalarChaser generates a series of single floating-point values that progressively change from initial value to destination value.
  • Hint: ROUTE value_changed output events to an interpolator node's set_fraction field, for example.

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).

  • Method Details

    • getDuration

      double getDuration()
      Provide double value in seconds within allowed range of [0,infinity) from initializeOnly SFTime field named duration.

      Tooltip: [0,+infinity) duration is the time interval for filter response in seconds.
      • Hint: duration is a nonnegative SFTime duration interval, not an absolute clock time.
      Specified by:
      getDuration in interface X3DChaserNode
      Returns:
      value of duration field

    • setDuration

      ScalarChaser setDuration​(double newValue)
      Accessor method to assign double value in seconds to initializeOnly SFTime field named duration.

      Tooltip: [0,+infinity) duration is the time interval for filter response in seconds.
      • Hint: duration is a nonnegative SFTime duration interval, not an absolute clock time.
      Specified by:
      setDuration in interface X3DChaserNode
      Parameters:
      newValue - is new value for the duration field.
      Returns:
      ScalarChaser - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

    • getInitialDestination

      float getInitialDestination()
      Provide float value from initializeOnly SFFloat field named initialDestination.

      Tooltip: Initial destination value for this node. *
      Returns:
      value of initialDestination field

    • setInitialDestination

      ScalarChaser setInitialDestination​(float newValue)
      Accessor method to assign float value to initializeOnly SFFloat field named initialDestination.

      Tooltip: Initial destination value for this node. *
      Parameters:
      newValue - is new value for the initialDestination field.
      Returns:
      ScalarChaser - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

    • getInitialValue

      float getInitialValue()
      Provide float value from initializeOnly SFFloat field named initialValue.

      Tooltip: Initial starting value for this node. *
      Returns:
      value of initialValue field

    • setInitialValue

      ScalarChaser setInitialValue​(float newValue)
      Accessor method to assign float value to initializeOnly SFFloat field named initialValue.

      Tooltip: Initial starting value for this node. *
      Parameters:
      newValue - is new value for the initialValue field.
      Returns:
      ScalarChaser - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

    • getIsActive

      boolean getIsActive()
      Provide boolean value from outputOnly SFBool field named isActive.

      Tooltip: isActive true/false events are sent when follower-node computation starts/stops.
      • Warning: it is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
      Specified by:
      getIsActive in interface X3DChaserNode
      Specified by:
      getIsActive in interface X3DFollowerNode
      Returns:
      value of isActive field

    • getMetadata

      X3DMetadataObject getMetadata()
      Provide X3DMetadataObject instance (using a properly typed node) from inputOutput SFNode field metadata.
      Specified by:
      getMetadata in interface X3DChaserNode
      Specified by:
      getMetadata in interface X3DChildNode
      Specified by:
