Method Detail

getSource

public String getSource()
Description copied from interface: SettingsProblem
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.

Specified by:
getSource in interface SettingsProblem
Returns:
The hint about the source of the problem or an empty string if unknown, never null.

getLineNumber

public int getLineNumber()
Description copied from interface: SettingsProblem
Gets the one-based index of the line containing the problem. The line number should refer to some text file that is given by SettingsProblem.getSource().

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

getColumnNumber

public int getColumnNumber()
Description copied from interface: SettingsProblem
Gets the one-based index of the column containing the problem. The column number should refer to some text file that is given by SettingsProblem.getSource().

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

getLocation

public String getLocation()
Description copied from interface: SettingsProblem
