  +--adavid.reflect.JavaFinder

public class JavaFinder

extends java.lang.Object

JavaFinder a java source finder: works on the class path and the property java.source.path which contains path to java source like CLASSPATH The property is given to the program via the command line with the option -Djava.source.path=... Something strange is that if we change dynamically java.class.path, the virtual machine does not take it into account! Zip files may be given in argument, with a special clause [sub directory] which says to search into the given sub directory ; this clause is ignored for normal directories.

Method Summary

static int	countDimensions(java.lang.String name) returns the number of dimensions of the given name, i.e.
static int	endOf(int pos, java.lang.String string) finds the end of a token
static java.lang.String	getFile(java.lang.String filename, java.lang.String extension) returns the string content of the given filename ; null if error
static java.lang.String	getjjSource(java.lang.Class aClass)
static java.lang.String	getjjSource(java.lang.String className) returns the jj source of a class; by absolute name ; null if not found, or error
static java.lang.String	getSource(java.lang.Class aClass) returns the source of a class:java or jj
static java.lang.String	getSource(java.lang.String className) returns the source of a class; by absolute name ; null if not found, or error
static Interval	getSourcePos(java.lang.String name, java.lang.String[] args, java.lang.String source) returns the interval where the source of the constructor/method can be found ; arguments are the name(short) and the arguments(long) not supported: type / comment / []...
static int	goBack(java.lang.String source, int pos) go back, jumps comments
static void	initJavaResource() initializes the java source resource This may be useful if the user changes the value of java.source.path and wants a dynamic update.
static int	jump(int pos, java.lang.String string) jump until the next token, ignoring comments, blanks and , if we are on a token, then jump first to the end of this token
