Class ReconcileWorkingCopyOperation

java.lang.Object

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

org.aspectj.org.eclipse.jdt.internal.core.ReconcileWorkingCopyOperation

public class ReconcileWorkingCopyOperation
extends JavaModelOperation

Reconcile a working copy and signal the changes through a delta.

High level summmary of what a reconcile does:

• populates the model with the new working copy contents
• fires a fine grained delta (flag F_FINE_GRAINED) describing the difference between the previous content and the new content (which method was added/removed, which field was changed, etc.)
• computes problems and reports them to the IProblemRequestor (begingReporting(), n x acceptProblem(...), endReporting()) iff (working copy is not consistent with its buffer || forceProblemDetection is set) && problem requestor is active
• produces a DOM AST (either JLS_2, JLS_3 or NO_AST) that is resolved if flag is set
• notifies compilation participants of the reconcile allowing them to participate in this operation and report problems

Method Detail

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

getWorkingCopy

protected CompilationUnit getWorkingCopy()

Returns the working copy this operation is working on.

isReadOnly

public boolean isReadOnly()

Description copied from class: JavaModelOperation

Returns true if this operation performs no resource modifications, otherwise false. Subclasses must override.

Overrides:

isReadOnly in class JavaModelOperation

makeConsistent

public CompilationUnit makeConsistent(CompilationUnit workingCopy)
                               throws JavaModelException

Throws:

JavaModelException

verify

protected IJavaModelStatus verify()

Description copied from class: JavaModelOperation

Returns a status indicating if there is any known reason this operation will fail. Operations are verified before they are run. Subclasses must override if they have any conditions to verify before this operation executes.

Overrides:

verify in class JavaModelOperation
