org.eclipse.ltk.core.refactoring
Class RefactoringStatus

java.lang.Object
  extended by 
org.eclipse.ltk.core.refactoring.RefactoringStatus

public class RefactoringStatus
extends Object

A RefactoringStatus object represents the outcome of a condition checking operation. It manages a list of RefactoringStatusEntry objects. Each RefactoringStatusEntry object describes one particular problem detected during condition checking.

Additionally a problem severity is managed. Severities are ordered as follows: OK < INFO < WARNING < ERROR < FATAL. The status's problem severity is the maximum of the severities of all entries. If the status doesn't have any entry the status's severity is OK.

Note: this class is not intended to be extended by clients.

Since:
3.0
See Also:
RefactoringStatusEntry, Refactoring.checkAllConditions(IProgressMonitor)
Restriction:
This class is not intended to be subclassed by clients.

Field Detail

OK

public static final int OK
Status severity constant (value 0) indicating this status represents the nominal case.

See Also:
Constant Field Values

INFO

public static final int INFO
Status severity constant (value 1) indicating this status is informational only.

See Also:
Constant Field Values

WARNING

public static final int WARNING
Status severity constant (value 2) indicating this status represents a warning.

Use this severity if the refactoring can be performed, but you assume that the user could not be aware of problems or confusions resulting from the execution.

See Also:
Constant Field Values

ERROR

public static final int ERROR
Status severity constant (value 3) indicating this status represents an error.

Use this severity if the refactoring can be performed, but the refactoring will not be behavior preserving and/or the partial execution will lead to an inconsistent state (e.g. compile errors).

See Also:
Constant Field Values

FATAL

public static final int FATAL
Status severity constant (value 4) indicating this status represents a fatal error.

Use this severity if the refactoring cannot be performed, and execution would lead to major problems. Note that this completely blocks the user from performing this refactoring. It is often preferable to use an ERROR status and allow a partial execution (e.g. if just one reference to a refactored element cannot be updated).
