Class ImportVisitor

java.lang.Object
  org.apache.bcel.classfile.EmptyVisitor
      org.apache.maven.shared.jar.classes.ImportVisitor

All Implemented Interfaces:

org.apache.bcel.classfile.Visitor

public class ImportVisitor
extends org.apache.bcel.classfile.EmptyVisitor

Implementation of a BCEL class visitor that analyzes a class and collects imports.

Field Summary

private java.util.List	imports The list of imports discovered.
private org.apache.bcel.classfile.JavaClass	javaClass The Java class that is being analyzed.
private static java.util.regex.Pattern	QUALIFIED_IMPORT_PATTERN Pattern to detect if the import is qualified and allows retrieval of the actual import name from the string via the group 1.
private static java.util.regex.Pattern	VALID_UTF8_PATTERN Pattern that checks whether a string is valid UTF-8.

Constructor Summary

ImportVisitor(org.apache.bcel.classfile.JavaClass javaClass)
Create an Import visitor.

Method Summary

java.util.List	getImports() Get the list of discovered imports.
void	visitConstantClass(org.apache.bcel.classfile.ConstantClass constantClass) Find any formally declared import in the Constant Pool.
void	visitConstantUtf8(org.apache.bcel.classfile.ConstantUtf8 constantUtf8) Find any package class Strings in the UTF8 String Pool.
