Interface Loader

All Known Implementing Classes:
LoaderBase, Lw3dLoader, ObjectFile

public interface Loader

The Loader interface is used to specify the location and elements of a file format to load. The interface is used to give loaders of various file formats a common public interface. Ideally the Scene interface will be implemented to give the user a consistent interface to extract the data.

Method Detail

load

Scene load(java.lang.String fileName)
           throws java.io.FileNotFoundException,
                  IncorrectFormatException,
                  ParsingErrorException
This method loads the named file and returns the Scene containing the scene. Any data files referenced by this file should be located in the same place as the named file; otherwise users should specify an alternate base path with the setBasePath(String) method.

Throws:
java.io.FileNotFoundException
IncorrectFormatException
ParsingErrorException

load

Scene load(java.net.URL url)
           throws java.io.FileNotFoundException,
                  IncorrectFormatException,
                  ParsingErrorException
This method loads the named file and returns the Scene containing the scene. Any data files referenced by the Reader should be located in the same place as the named file; otherwise, users should specify an alternate base path with the setBaseUrl(URL) method.

Throws:
java.io.FileNotFoundException
IncorrectFormatException
ParsingErrorException

load

Scene load(java.io.Reader reader)
           throws java.io.FileNotFoundException,
                  IncorrectFormatException,
                  ParsingErrorException
This method loads the Reader and returns the Scene containing the scene. Any data files referenced by the Reader should be located in the user's current working directory.

Throws:
java.io.FileNotFoundException
IncorrectFormatException
ParsingErrorException

setBaseUrl

void setBaseUrl(java.net.URL url)
This method sets the base URL name for data files associated with the file passed into the load(URL) method. The basePath should be null by default, which is an indicator to the loader that it should look for any associated files starting from the same directory as the file passed into the load(URL) method.


setBasePath

void setBasePath(java.lang.String pathName)
This method sets the base path name for data files associated with the file passed into the load(String) method. The basePath should be null by default, which is an indicator to the loader that it should look for any associated files starting from the same directory as the file passed into the load(String) method.


getBaseUrl

java.net.URL getBaseUrl()
Returns the current base URL setting. By default this is null, implying the loader should look for associated files starting from the same directory as the file passed into the load(URL) method.


getBasePath

java.lang.String getBasePath()
Returns the current base path setting. By default this is null, implying the loader should look for associated files starting from the same directory as the file passed into the load(String) method.


setFlags

void setFlags(int flags)
This method sets the load flags for the file. The flags should equal 0 by default (which tells the loader to only load geometry). To enable the loading of any particular scene elements, pass in a logical OR of the LOAD values specified above.


getFlags

int getFlags()
Returns the current loading flags setting.
