Method Detail

afterTraverse

public void afterTraverse(TypeAnalyzer analyzer,
                          org.eclipse.jdt.core.dom.CompilationUnit root)

Rename the occurance of package names after the AST is traversed. The transformer implemented for this rule traverses the AST once again and looks up package names that need to be changed.

Due to the change of the package that the class belongs to, originally accessible classes in the same package may becomes inaccessable. This transformer explicitly imports those classes when necessary. Unfortunately, protected classes originally in the same package may not be imported, and protected members of other classes in that package are no longer accessible. It is the user's responsibility to ensure that those cases do not happen.

Specified by:

afterTraverse in class TransformRule

Parameters:

analyzer - The type analyzer.

root - The root of the AST.

TransformRule.beforeTraverse(TypeAnalyzer, CompilationUnit)

beforeTraverse

public void beforeTraverse(TypeAnalyzer analyzer,
                           org.eclipse.jdt.core.dom.CompilationUnit root)

Execute actions before the AST is traversed. (Not necessary for this rule.)

Specified by:

beforeTraverse in class TransformRule

Parameters:

analyzer - The type analyzer.

root - The root of the AST.
