Method Detail

getSource

String getSource()

Gets the hint about the source of the problem. While the syntax of this hint is unspecified and depends on the creator of the problem, the general expectation is that the hint provides sufficient information to the user to track the problem back to its origin. A concrete example for such a source hint can be the file path or URL from which the settings were read.

Returns:

The hint about the source of the problem or an empty string if unknown, never null.

getLineNumber

int getLineNumber()

Gets the one-based index of the line containing the problem. The line number should refer to some text file that is given by getSource().

Returns:

The one-based index of the line containing the problem or a non-positive value if unknown.

getColumnNumber

int getColumnNumber()

Gets the one-based index of the column containing the problem. The column number should refer to some text file that is given by getSource().

Returns:

The one-based index of the column containing the problem or non-positive value if unknown.

getLocation

String getLocation()

Gets the location of the problem. The location is a user-friendly combination of the values from getSource(), getLineNumber() and getColumnNumber(). The exact syntax of the returned value is undefined.

Returns:

The location of the problem, never null.

getException

Exception getException()

Gets the exception that caused this problem (if any).

Returns:

The exception that caused this problem or null if not applicable.

getMessage

String getMessage()

Gets the message that describes this problem.
