MetadataSet (X3DJSAIL, X3D Java Scene Access Interface Library)

All Superinterfaces:

X3DMetadataObject, X3DNode

All Known Implementing Classes:

MetadataSetObject
```
public interface MetadataSet
extends X3DNode, X3DMetadataObject
```
The metadata provided by this node is contained in the metadata nodes of the value field.

X3D node tooltip: [X3DNode,X3DMetadataObject] MetadataSet contains a list of Metadata* nodes that each have containerField="value" and together provide information about the parent node of the MetadataSet. Further information about this specific MetadataSet 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: MetadataSet can contain other MetadataSet nodes.
- 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.

  - addValue
```
void addValue(X3DNode[] newValue)
```
    Add array of child value nodes to array of existing nodes (if any).

    Parameters:
    
    newValue - is new value array to be appended the value field.
  - setValue
```
void setValue(X3DNode 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 X3DNode
    
    Parameters:
    
    newValue - is new value for the DEF field.

  - setUSE
```
MetadataSet 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 X3DNode
    
    Parameters:
    
    newValue - is new value for the USE field.
    
    Returns:
    
    MetadataSet - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

  - setCssClass
```
MetadataSet setCssClass(java.lang.String newValue)
```
    Assign String value to inputOutput SFString field named class.
    
    Specified by:
    
    setCssClass in interface X3DNode
    
    Parameters:
    
    newValue - is new value for the class field.
    
    Returns:
    
    MetadataSet - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
