Description Olivier Thomann CLA 2003-07-18 11:35:41 EDT 
It could be useful to be able to create only a subpart of a compilation unit
instead of the whole compilation unit when the user knows that the interesting
part is located in a method.
In this case only this method should have its statement created in the resulting
DOM/AST.
Comment 1 Olivier Thomann CLA 2003-07-18 11:37:10 EDT 
Suggested API on org.eclipse.jdt.core.dom.AST:
public static CompilationUnit parsePartialCompilationUnit(		ICompilationUnit unit,
int position,
boolean resolveBindings)

public static CompilationUnit parsePartialCompilationUnit(
	ICompilationUnit unit,
	int position,
	boolean resolveBindings,
	WorkingCopyOwner owner)
Comment 2 Olivier Thomann CLA 2003-07-18 11:37:28 EDT 
Changed milestone.
Comment 3 Olivier Thomann CLA 2003-07-18 12:44:32 EDT 
Jim, could you please review the javadoc? When done, please reassign it to me
and I will close it.

Regression tests added.
Comment 4 Jim des Rivieres CLA 2003-07-24 16:29:36 EDT 
Made minor improvements to wording of spec. Dirk or Martin should review to
ensure this is what is needed.

Olivier: The implementation should quietly ignore source positions that are 
negative or completely out of range.

(I also added some missing owner !=null checks to the AST.parse... methods 
that take a WorkingCopyOwner.)
Comment 5 Olivier Thomann CLA 2003-07-29 13:47:27 EDT 
Added bound checks.
Fixed and released in HEAD.
Regression tests added in jdt/ui tests and jdt/core dom tests.
Reopen if this is not what you wanted.
Comment 6 David Audel CLA 2003-08-28 04:48:37 EDT 
Verified.
