Field Detail
MAX_LOOPS
final public static int MAX_LOOPS(Code)
Maximum number of loops for looking for indirect dependencies.




Constructor Detail
AbstractAnalyzer
protected AbstractAnalyzer()(Code)
Setup the analyzer




Method Detail
addClassPath
public void addClassPath(Path classPath)(Code)
Add a classpath to the classpath being used by the analyzer. The classpath contains the binary classfiles for the classes being analyzed The elements may either be the directories or jar files.Not all analyzers will use this information.
Parameters:
  classPath - the Path instance specifying the classpath elements



addRootClass
public void addRootClass(String className)(Code)
Add a root class. The root classes are used to drive the determination of dependency information. The analyzer will start at the root classes and add dependencies from there.
Parameters:
  className - the name of the class in Java dot notation.



addSourcePath
public void addSourcePath(Path sourcePath)(Code)
Add a source path to the source path used by this analyzer. The elements in the given path contain the source files for the classes being analyzed. Not all analyzers will use this information.
Parameters:
  sourcePath - The Path instance specifying the source pathelements.



config
public void config(String name, Object info)(Code)
Configure an aspect of the analyzer. The set of aspects that are supported is specific to each analyzer instance.
Parameters:
  name - the name of the aspect being configured
Parameters:
  info - the configuration info.



determineDependencies
abstract protected void determineDependencies(Vector files, Vector classes)(Code)
Determine the dependencies of the current set of root classes
Parameters:
  files - a vector into which Files upon which the root classesdepend should be placed.
Parameters:
  classes - a vector of Strings into which the names of classesupon which the root classes depend should be placed.



getClassContainer
public File getClassContainer(String classname) throws IOException(Code)
Get the file that contains the class definition
Parameters:
  classname - the name of the required class the file instance, zip or class, containing theclass or null if the class could not be found.
exception:
  IOException - if the files in the classpath cannot be read.



getClassDependencies
public Enumeration getClassDependencies()(Code)
Get the list of classes upon which root classes depend. This is a list of Java classnames in dot notation. an enumeration of Strings, each being the name of a Javaclass in dot notation.



getFileDependencies
public Enumeration getFileDependencies()(Code)
Get the list of files in the file system upon which the root classes depend. The files will be either the classfiles or jar files upon which the root classes depend. an enumeration of File instances.



getRootClasses
protected Enumeration getRootClasses()(Code)
Get an enumeration of the root classes an enumeration of Strings, each of which is a class namefor a root class.



getSourceContainer
public File getSourceContainer(String classname) throws IOException(Code)
Get the file that contains the class source.
Parameters:
  classname - the name of the required class the file instance, zip or java, containing thesource or null if the source for the class could not be found.
exception:
  IOException - if the files in the sourcepath cannot be read.



isClosureRequired
protected boolean isClosureRequired()(Code)
Indicate if the analyzer is required to follow indirect class relationships. true if indirect relationships should be followed.



reset
public void reset()(Code)
Reset the dependency list. This will reset the determined dependencies and the also list of root classes.



setClosure
public void setClosure(boolean closure)(Code)
Set the closure flag. If this flag is true the analyzer will traverse all class relationships until it has collected the entire set of direct and indirect dependencies
Parameters:
  closure - true if dependencies should be traversed to determineindirect dependencies.



supportsFileDependencies
abstract protected boolean supportsFileDependencies()(Code)
Indicate if the particular subclass supports file dependency information. true if file dependencies are supported.
