Polyline2D (X3DJSAIL, X3D Java Scene Access Interface Library)

All Superinterfaces:

X3DGeometryNode, X3DNode

All Known Implementing Classes:

Polyline2DObject
```
public interface Polyline2D
extends X3DGeometryNode
```
Abstract node interface, defined by X3D specification to support X3D Java interoperability.

X3D node tooltip: [X3DGeometryNode] Polyline2D is a geometry node that defines a connected set of vertices in a contiguous set of line segments in X-Y plane.
- Hint: Material emissiveColor in corresponding Appearance is used for rendering lines.
- Warning: lines are not lit, are not texture-mapped, and do not participate in collision detection.
- Warning: use a different Material emissiveColor than the Background color, otherwise geometry is invisible.
- Hint: adding LineProperties to the corresponding Appearance node can modify the rendering style of these lines.
- Hint: insert a Shape node before adding geometry or Appearance. Example: X3D Example Archives, X3D for Web Authors, Chapter 10 Geometry 2D

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

- Method Detail
  - getLineSegments
```
float[] getLineSegments()
```
    Provide array of 2-tuple float results from initializeOnly MFVec2f field named lineSegments.
    
    Tooltip: Coordinates of vertices connected into contiguous Polyline2D.
    - Warning: simple-geometry dimensions are initializeOnly and cannot be changed after initial creation, for size animation use an ancestor Transform scale instead.
    Returns:
    
    value of lineSegments field
  - setLineSegments
```
Polyline2D setLineSegments(float[] newValue)
```
    Assign 2-tuple float array to initializeOnly MFVec2f field named lineSegments.
    
    Tooltip: Coordinates of vertices connected into contiguous Polyline2D. Warning: simple-geometry dimensions are initializeOnly and cannot be changed after initial creation, for size animation use an ancestor Transform scale instead.
    
    Parameters:
    
    newValue - is new value for the lineSegments field.
    
    Returns:
    
    Polyline2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
  - getMetadata
```
X3DMetadataObject getMetadata()
```
    Provide X3DMetadataObject instance (using a properly typed node) from inputOutput SFNode field metadata.
    
    Specified by:
    
    getMetadata in interface X3DGeometryNode
    
    Specified by:
    
    getMetadata in interface X3DNode
    
    Returns:
    
    value of metadata field
    
    See Also:
    
    X3D Scene Authoring Hints: Metadata Nodes
  - setMetadata
```
Polyline2D setMetadata(X3DMetadataObject newValue)
```
    Assign X3DMetadataObject instance (using a properly typed node) to inputOutput SFNode field metadata.
    
    Specified by:
    
    setMetadata in interface X3DGeometryNode
    
    Specified by:
    
    setMetadata in interface X3DNode
    
    Parameters:
    
    newValue - is new value for the metadata field.
    
    Returns:
    
    Polyline2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

    X3D Scene Authoring Hints: Metadata Nodes
  - setDEF
```
Polyline2D setDEF(java.lang.String newValue)
```
    Assign String value to inputOutput SFString field named DEF.
    
    Tooltip: DEF defines a unique ID name for this node, referenceable by other nodes. Hint: descriptive DEF names improve clarity and help document a model. Hint: well-defined names can simplify design and debugging through improved author understanding. Hint: X3D Scene Authoring Hints, Naming Conventions http://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions
    
    Note that setting the DEF value clears the USE value.
    
    Specified by:
    
    setDEF in interface X3DGeometryNode
    
    Specified by:
    
    setDEF in interface X3DNode
    
    Parameters:
    
    newValue - is new value for the DEF field.
    
    Returns:
    
    Polyline2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
  - setUSE
```
Polyline2D setUSE(java.lang.String newValue)
```
    Assign String value to inputOutput SFString field named USE.
    
    Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value). Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance. Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute. Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.
    
    Note: each USE node is still an independent object, with the USE value matching the DEF value in the preceding object.
    
    Warning: invoking the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.
    
    Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.
    
    Specified by:
    
    setUSE in interface X3DGeometryNode
    
    Specified by:
    
    setUSE in interface X3DNode
    
    Parameters:
    
    newValue - is new value for the USE field.
    
    Returns:
    
    Polyline2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
  - setCssClass
```
Polyline2D setCssClass(java.lang.String newValue)
```
    Assign String value to inputOutput SFString field named class.
    
    Tooltip: The class attribute is a space-separated list of classes, reserved for use by CSS cascading stylesheets. Warning: currently the class attribute is only supported in XML encoding of X3D scenes. Hint: W3C Cascading Style Sheets https://www.w3.org/Style/CSS
    
    Specified by:
    
    setCssClass in interface X3DGeometryNode
    
    Specified by:
    
    setCssClass in interface X3DNode
    
    Parameters:
    
    newValue - is new value for the class field.
    
    Returns:
    
    Polyline2D - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
