org.aspectj.org.eclipse.jdt.internal.core.JavaModelOperation

org.aspectj.org.eclipse.jdt.internal.core.CreateElementInCUOperation

org.aspectj.org.eclipse.jdt.internal.core.CreatePackageDeclarationOperation

All Implemented Interfaces:

org.eclipse.core.resources.IWorkspaceRunnable, org.eclipse.core.runtime.ICoreRunnable, org.eclipse.core.runtime.IProgressMonitor

public class CreatePackageDeclarationOperation
extends CreateElementInCUOperation

This operation adds/replaces a package declaration in an existing compilation unit. If the compilation unit already includes the specified package declaration, it is not generated (it does not generate duplicates).

Required Attributes:

• Compilation unit element
• Package name
