public class LayerSet
extends X3DConcreteNode
implements LayerSet

LayerSet defines a list of layers and a rendering order.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. LayerSet node tooltip: (X3D version 3.2 or later) [X3DNode] LayerSet defines a list of layers and a rendering order. The rendering order is specified by the order field.

• Hint: the layer first specified in the order field is the first layer rendered and appears below any other layers. The layer last specified in the order field is the last layer rendered and correspondingly appears on top of all other layers.
• Warning: only one LayerSet node is allowed in a scene, and it shall be a root node at the top of the scene graph.
• Hint: X3D Architecture 35.2.1 Overview of layering https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS /Part01/components/layering.html#OverviewOfLayering

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.

• Hint: X3D Scene Authoring Hints, Naming Conventions https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions

Overrides:

getDEF in class X3DConcreteNode

Returns:

value of DEF field

See Also:

• X3D Scene Authoring Hints: Naming Conventions

setDEF

public final LayerSet setDEF(String newValue)

Accessor method to 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 https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions

Note that setting the DEF value clears the USE value.

Specified by:

Parameters:

newValue - is new value for the DEF field.

Returns:

LayerSet - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

Returns:

LayerSet - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

getUSE

public String getUSE()

Provide String value from 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.

Overrides:

getUSE in class X3DConcreteNode

Returns:

value of USE field

See Also:

• X3D Scene Authoring Hints: Naming Conventions

setUSE

public final LayerSet setUSE(String newValue)

Accessor method to 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 class X3DConcreteNode
