MetadataDoubleObject (X3DJSAIL, X3D Java Scene Access Interface Library)

java.lang.Object
- org.web3d.x3d.jsail.X3DConcreteElement
- - org.web3d.x3d.jsail.X3DConcreteNode
  - - org.web3d.x3d.jsail.Core.MetadataDoubleObject

All Implemented Interfaces:

MetadataDouble, X3DMetadataObject, X3DNode
```
public class MetadataDoubleObject
extends X3DConcreteNode
implements MetadataDouble
```
The metadata provided by this node is contained in the double-precision floating point numbers of the value field.

X3D node tooltip: [X3DNode,X3DMetadataObject] MetadataDouble contains a typed list of values providing metadata information about its parent node. Further information about this specific Metadata* node may be provided by a single child Metadata* node with containerField="metadata".
- Hint: use containerField="value" if the parent node is MetadataSet.
- Hint: if a metadata node is needed as a top-level root node for the scene, first insert a parent WorldInfo (or WorldInfo/MetadataSet) to contain it.
- Hint: if present, an IS statement is the first child within any other node.
- Hint: an IS statement precedes any sibling Metadata* node, which in turn precedes any other sibling nodes.
- Hint: The choice of MetadataDouble versus MetadataFloat usually depends on the relevant tool utilizing the value, or else the relevant metadata reference defining the value.
- Hint: comments are not readable when a model file is loaded for viewing, but WorldInfo and Metadata* nodes are persistent and inspectable at run time.
- Hint: X3D for Web Authors, Chapter 15, Metadata Information

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.

    Parameters:
    
    newValue - is new value for the value field.
    
    Returns:
    
    MetadataDoubleObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

  - setDEF
```
public final MetadataDoubleObject 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 MetadataDouble
    
    Specified by:
    
    setDEF in interface X3DNode
    
    Specified by:
    
    setDEF in class X3DConcreteNode
    
    Parameters:
    
    newValue - is new value for the DEF field.
    
    Returns:
    
    MetadataDoubleObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

  - setDEF
```
public MetadataDoubleObject setDEF(SFStringObject newValue)
```
    Assign typed object value to SFString DEF field, similar to setDEF(String).
    
    Parameters:
    
    newValue - is new value for the DEF field.
    
    Returns:
    
    MetadataDoubleObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
  - setUSE
```
public final MetadataDoubleObject 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.
