Enum Constant Summary

Enum Constants

Enum Constant and Description
CANCEL Severity constant indicating a deliberate cancellation of the parsing operation by the user.
ERROR Severity constant indicating an error problem that does not prevent the parser from proceeding, but which does indicate an ill-formed construct.
FATAL Severity constant indicating an error problem that prevents the parser from continuing to process the remainder of the input.
INFO Severity constant indicating an informational message that, really, is not a problem but a hint or suggestion.
OK Severity constant indicating absence of any problem.
WARNING Severity constant indicating a warning problem.

Enum Constant Detail

OK

public static final ProblemHandler.Severity OK

Severity constant indicating absence of any problem. Corresponds to the EMF Diagnostic severity Diagnostic.OK and Eclipse IStatus.OK.

INFO

public static final ProblemHandler.Severity INFO

Severity constant indicating an informational message that, really, is not a problem but a hint or suggestion. Corresponds to the EMF Diagnostic severity Diagnostic.INFO and Eclipse IStatus.INFO.

WARNING

public static final ProblemHandler.Severity WARNING

Severity constant indicating a warning problem. Corresponds to the EMF Diagnostic severity Diagnostic.WARNING and Eclipse IStatus.WARNING.

ERROR

public static final ProblemHandler.Severity ERROR

Severity constant indicating an error problem that does not prevent the parser from proceeding, but which does indicate an ill-formed construct. Corresponds to the EMF Diagnostic severity Diagnostic.ERROR and Eclipse IStatus.ERROR.

FATAL

public static final ProblemHandler.Severity FATAL

Severity constant indicating an error problem that prevents the parser from continuing to process the remainder of the input. Corresponds to the EMF Diagnostic severity Diagnostic.ERROR and Eclipse IStatus.ERROR, because these frameworks do not distinguish between fatal and non-fatal conditions.

CANCEL

public static final ProblemHandler.Severity CANCEL

Severity constant indicating a deliberate cancellation of the parsing operation by the user. Corresponds to the EMF Diagnostic severity Diagnostic.CANCEL and Eclipse IStatus.CANCEL. Cancellation in both of these frameworks, and in OCL, does not actually indicate an error condition despite its having the highest value. However, an operation that was canceled is incomplete and any results produced are necessarily invalid as in the case of FATAL errors.

Method Detail

values

public static ProblemHandler.Severity[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ProblemHandler.Severity c : ProblemHandler.Severity.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ProblemHandler.Severity valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getDiagnosticSeverity

public int getDiagnosticSeverity()

isOK

public boolean isOK()

Am I the "OK" severity?

Returns:

whether I am OK

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<ProblemHandler.Severity>
