All Implemented Interfaces:

MetadataSet, X3DMetadataObject, X3DNode

public class MetadataSet
extends X3DConcreteNode
implements MetadataSet

The metadata provided by this node is contained in the metadata nodes of the value field.

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. MetadataSet 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: typically use containerField="value" if the parent node is MetadataSet.
• Warning: default containerField="metadata" in X3D 3 changed to default containerField="value" in X3D 4.0, allowing construction of much terser MetadataSet vocabulary structures.
• Hint: explicitly defining containerField for Metadata nodes is always allowed and also unambiguous across each version of X3D.
• Hint: each of the Metadata nodes are allowed as top-level root nodes in a scene, if doing that be sure to explicitly define containerField='metadata'. https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01/concepts.html#Rootnodes
• Warning: Metadata nodes can only contain other Metadata nodes.
• 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.
• Hint: X3D for Web Authors, Chapter 15, Metadata Information https://www.web3d.org/x3d/content/examples/X3dForWebAuthors/Chapter15-Metadata/Chapter15-MetadataInformation.html

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.

setDEF in class X3DConcreteNode

Parameters:

newValue - is new value for the DEF field.

Returns:

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

See Also:

• X3D Scene Authoring Hints: Metadata Nodes

setDEF

public MetadataSet setDEF(SFString newValue)

Assign typed object value to SFString DEF field, similar to setDEF(String).

Parameters:

newValue - is new value for the DEF field.

Returns:

MetadataSet - 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 MetadataSet 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

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).
