Interface MetadataDouble

All Superinterfaces:

X3DMetadataObject, X3DNode

All Known Implementing Classes:

MetadataDouble

public interface MetadataDouble
extends X3DNode, X3DMetadataObject

The metadata provided by this node is contained in the double-precision floating point numbers 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. MetadataDouble 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: 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: 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.

Method Details

getMetadata

X3DMetadataObject getMetadata()

Provide org.web3d.x3d.sai.Core.X3DMetadataObject instance (using a properly typed node) from inputOutput SFNode field metadata.

Tooltip: [X3DMetadataObject] Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.

• Hint: X3D Architecture 7.2.4 Metadata https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS /Part01/components/core.html#Metadata

Specified by:

getMetadata in interface X3DNode

Returns:

value of metadata field

See Also:

• X3D Scene Authoring Hints: Metadata Nodes

setMetadata

MetadataDouble setMetadata(X3DMetadataObject newValue)

Accessor method to assign org.web3d.x3d.sai.Core.X3DMetadataObject instance (using a properly typed node) to inputOutput SFNode field metadata.

Tooltip: [X3DMetadataObject] Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.

• Hint: X3D Architecture 7.2.4 Metadata https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS /Part01/components/core.html#Metadata

Specified by:

setMetadata in interface X3DNode

Parameters:

newValue - is new value for the metadata field.

Returns:

MetadataDouble - 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

getName

String getName()

Provide String value from inputOutput SFString field named name.

Tooltip: Depending on the metadata vocabulary, the attribute name is usually required for metadata nodes.

• Warning: name field is not included if this instance is a USE node, in order to avoid potential mismatches.
• 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

Specified by:

getName in interface X3DMetadataObject

Returns:

value of name field

setName

MetadataDouble setName(String newValue)

Accessor method to assign String value to inputOutput SFString field named name.

Tooltip: Depending on the metadata vocabulary, the attribute name is usually required for metadata nodes.

• Warning: name field is not included if this instance is a USE node, in order to avoid potential mismatches.
• 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

@see X3D Scene Authoring Hints: Naming Conventions

Specified by:

setName in interface X3DMetadataObject

Parameters:

newValue - is new value for the name field.

Returns:

MetadataDouble - 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

getReference

String getReference()

Provide String value from inputOutput SFString field named reference.

Tooltip: Reference to the metadata standard or definition defining this particular metadata value. *

Specified by:

getReference in interface X3DMetadataObject

Returns:

value of reference field

setReference

MetadataDouble setReference(String newValue)

Accessor method to assign String value to inputOutput SFString field named reference.

Tooltip: Reference to the metadata standard or definition defining this particular metadata value. *

Specified by:

setReference in interface X3DMetadataObject

Parameters:

newValue - is new value for the reference field.

Returns:

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

• X3D Scene Authoring Hints: Metadata Nodes

getValue

double[] getValue()

Provide array of double results from inputOutput MFDouble field named value.

Tooltip: The value attribute is a strictly typed data array providing relevant metadata information.

• Hint: many XML tools substitute XML character references for special characters automatically if needed within an attribute value (such as & for & ampersand character, or " for " quotation-mark character).

Returns:

value of value field

setValue

MetadataDouble setValue(double[] newValue)

Accessor method to assign double array to inputOutput MFDouble field named value.

Tooltip: The value attribute is a strictly typed data array providing relevant metadata information.

• Hint: many XML tools substitute XML character references for special characters automatically if needed within an attribute value (such as & for & ampersand character, or " for " quotation-mark character).

Parameters:

newValue - is new value for the value field.
