   org.codehaus.groovy.tools.LoaderConfiguration

LoaderConfiguration
public class LoaderConfiguration (Code)
class used to configure a RootLoader from a stream or by using it's methods. The stream can be for example a FileInputStream from a file with the following format: # comment main is classname load path load file load pathWith${property} load path/*.jar
  • All lines starting with "#" are ignored.
  • The "main is" part may only be once in the file. The String afterwards is the name of a class if a main method.
  • The "load" command will add the given file or path to the classpath in this configuration object.
Defining the main class is optional if @see #setRequireMain(boolean) was called with false, before reading the configuration. You can use the wildcard "*" to filter the path, but only for files, not directories. The ${propertyname} is replaced by the value of the system's propertyname. You can use user.home here for example. If the property does not exist, an empty string will be used. If the path or file after the load does not exist, the path will be ignored.

Constructor Detail
LoaderConfiguration
public LoaderConfiguration()(Code)
creates a new loader configuration




Method Detail
addClassPath
public void addClassPath(String path)(Code)
adds a classpath to this configuration. It expects a string with multiple paths, seperated by the system dependent
See Also:   java.io.File.pathSeparator



addFile
public void addFile(File f)(Code)
adds a file to the classpath if it does exist



addFile
public void addFile(String s)(Code)
adds a file to the classpath if it does exist



configure
public void configure(InputStream is) throws IOException(Code)
configures this loader with a stream
Parameters:
  is - stream used to read the configuration
throws:
  IOException - if reading or parsing the contents of the stream fails



getClassPathUrls
public URL[] getClassPathUrls()(Code)
gets a classpath as URL[] from this configuration. This can be used to construct a @see java.net.URLClassLoader



getMainClass
public String getMainClass()(Code)
returns the main class or null is no is defined



setMainClass
public void setMainClass(String clazz)(Code)
sets the main class. If there is already a main class it is overwritten. Calling @see #configure(InputStream) after calling this method does not require a main class definition inside the stream



setRequireMain
public void setRequireMain(boolean requireMain)(Code)
if set to false no main class is required when calling
