public class CommitWorkingCopyOperation
extends JavaModelOperation

Commits the contents of a working copy compilation unit to its original element and resource, bringing the Java Model up-to-date with the current contents of the working copy.

It is possible that the contents of the original resource have changed since the working copy was created, in which case there is an update conflict. This operation allows for two settings to resolve conflict set by the fForce flag:

• force flag is false - in this case an JavaModelException is thrown
• force flag is true - in this case the contents of the working copy are applied to the underlying resource even though the working copy was created before a subsequent change in the resource

The default conflict resolution setting is the force flag is false A JavaModelOperation exception is thrown either if the commit could not be performed or if the new content of the compilation unit violates some Java Model constraint (e.g. if the new package declaration doesn't match the name of the folder containing the compilation unit).

Constructor Details

CommitWorkingCopyOperation

public CommitWorkingCopyOperation(ICompilationUnit element,
 boolean force)

Constructs an operation to commit the contents of a working copy to its original compilation unit.

Method Details

executeOperation

protected void executeOperation()
                         throws JavaModelException

Description copied from class: JavaModelOperation

Performs the operation specific behavior. Subclasses must override.

Specified by:

executeOperation in class JavaModelOperation

Throws:

JavaModelException - if setting the source of the original compilation unit fails

getCompilationUnit

protected CompilationUnit getCompilationUnit()

Returns the compilation unit this operation is working on.

getSchedulingRule

protected org.eclipse.core.runtime.jobs.ISchedulingRule getSchedulingRule()

Overrides:

getSchedulingRule in class JavaModelOperation

verify

public IJavaModelStatus verify()

Possible failures:

• INVALID_ELEMENT_TYPES - the compilation unit supplied to this operation is not a working copy
• ELEMENT_NOT_PRESENT - the compilation unit the working copy is based on no longer exists.
• UPDATE_CONFLICT - the original compilation unit has changed since the working copy was created and the operation specifies no force
• READ_ONLY - the original compilation unit is in read-only mode

Overrides:

verify in class JavaModelOperation
