Dependencies Example

Consider the following class (the source is available in src/test/java/mete/testing/misc/DependenciesEG.java):

public class DependenciesEG extends EmptyRoot implements EmptyInterface {
  private MethodV field;
  public int method(OneString arg) {
    field.methodV();
    if (arg.sField.equals("")) {
      return 0;
    } else {
      return 1;
    }
  }
}

It dependencies can be determined as follows (using mete-tools ability to analysis classfiles directly):

java -Dprocessing=Dependencies -Dformat=Text \
     -Devidence=Raw -Dwarnings=None \
     -Dsource=Classfiles -DappID=eg -Dpackages=mete.testing \
     -Xmx1000m -jar mete-tools.jar \
     target/classes/mete/testing/misc/DependenciesEG.class

The result would be a list of all dependencies found in the class, which are listed below (module names are usually listed with their full binary name, but just the classnames are given here for space reasons):

From From Kind To Type targetID Location locationID Visibility

A DependenciesEG Class OneString Get sField Method method(OneString) Private

B DependenciesEG Class fields.OneString Parameter to whole module Method method(OneString) Public

C DependenciesEG Class MethodV Field to whole module Field field Private

D DependenciesEG Class MethodV InvokeVirtual methodV() Method method(OneString) Private

E DependenciesEG Class DependenciesEG Get field Method method(OneString) Private

F DependenciesEG Class EmptyInterface Implements to whole module Header Public

G DependenciesEG Class EmptyRoot Extends to whole module Header Public

H DependenciesEG Class EmptyRoot InvokeSpecial <init>() Constructor <init>() Private

	From	From Kind	To	Type	targetID	Location	locationID	Visibility
A	DependenciesEG	Class	OneString	Get	sField	Method	method(OneString)	Private
B	DependenciesEG	Class	fields.OneString	Parameter	to whole module	Method	method(OneString)	Public
C	DependenciesEG	Class	MethodV	Field	to whole module	Field	field	Private
D	DependenciesEG	Class	MethodV	InvokeVirtual	methodV()	Method	method(OneString)	Private
E	DependenciesEG	Class	DependenciesEG	Get	field	Method	method(OneString)	Private
F	DependenciesEG	Class	EmptyInterface	Implements	to whole module	Header		Public
G	DependenciesEG	Class	EmptyRoot	Extends	to whole module	Header		Public
H	DependenciesEG	Class	EmptyRoot	InvokeSpecial	<init>()	Constructor	<init>()	Private

Points to note:

Dependencies by a module on itself are reported (E)
The (required) invocation of a constructor in the superclass (include that of java.lang.Object) shows up explicitly (H).
The dependencies by DependenciesEG on the primitive type int (return type of method) and java.lang.String (invocation of equals) are not reported as they do not satisfy the requirement of being in the "application" being tested, in this case not belonging to the mete.testing package (see here). If such (outgoing) dependencies are to be reported, use the "all" option.
