Package GCF.DefaultImpl2

Class GXLOutputAPI

java.lang.Object
GCF.DefaultImpl2.GXLOutputAPI
public class GXLOutputAPI extends Object
This class is to centralize the output-management of the framework. It offers the createOutputFile(String outFile) and the closeOutputFile()- methods to handle an output File. If no output file is created, the standard-output "System.out" is used. Furthermore the methods write() and writeln() (whichs functionality should be clear) are offered. The setCurrentDepth()-method is used by the GCF.GXLConnector to let you know, what the current depth of the abstract Syntax is, so that you can layout your output accordingly. You can obtain the current depth over the getCurrentDepth()-method. For the Use of GXLOutputAPI see class "Demo" and the default-implementations. IMPORTANT : You have to copy the GXLOutputAPI into the same directory as your implementation of the GCF and to rename its package name into the package name of your implementation.
