Usage

From source file:maltcms.ui.fileHandles.properties.tools.SceneParser.java

/**
 * Supports both absolute and relative paths and also arbitrary combinations
 * of the two. In case of relative paths, the location of the file
 * containing the pipeline configuration is used as basedir to resolve the
 * relative path.//from w  w  w.j ava2  s  .co  m
 *
 * Example for relative path:
 * <pre>pipelines.properties = fragmentCommands/myClassName.properties</pre>
 * Example for absolute path:
 * <pre>pipelines.properties = /home/juser/myFunkyDir/myClassName.properties</pre>
 *
 * <pre>pipeline.properties</pre> accepts multiple entries, separated by a
 * ',' (comma) character. Example:
 * <pre>pipeline.properties = fragmentCommands/myClassName.properties,/home/juser/myFunkyDir/myClassName.properties</pre>
 *
 * @param filename the filename of the base configuration, which contains
 * the pipeline= and pipeline.properties keys.
 * @param cfg the configuration object resembling the content of filename.
 * @param scene the graph scene into which to load the configuration.
