Constructor Details

SceneMetaData

protected SceneMetaData(String ver,
 boolean vrml,
 int enc)

Create a new metadata instance for a scene that describes the given subset of information of the specification.

Parameters:

ver - The version string to be supported

vrml - true if this is a VRMLX spec, false for X3D

enc - The encoding type used for the source file

SceneMetaData

public SceneMetaData(SceneMetaData src)

Create a new, non-writable instance that copies the information from the given source

Parameters:

src - The metadata to source the information from

Method Details

getVersion

public String getVersion()

Get the specification version name that was used to describe this scene. The version is a string that is relative to the specification used and is in the format "X.Y" where X and Y are integer values describing major and minor versions, respectively.

Returns:

The version used for this scene

isVrmlSpec

public boolean isVrmlSpec()

Get the flag indicating what specification this is referring to.

Returns:

true if this is a VRML spec, false for X3D

getEncoding

public int getEncoding()

Get the encoding of the original file type.

Returns:

The encoding description

getProfileName

public String getProfileName()

Get the name of the profile used by this scene. If the profile is not set, will return null.

Returns:

The name of the profile, or null

getComponents

public ComponentInfo[] getComponents()

Get the list of all the components declared in the scene. If there were no components registered, this will return null.

Returns:

The components declared or null

getMetaData

public Map<String,String> getMetaData()

Get the meta data mapping from this scene. The map returned cannot be changed and represents the current internal state.

Returns:

The current meta tag mappings
