Examples of org.tmatesoft.svn.core.SVNErrorMessage

org.tmatesoft.svn.core.SVNErrorMessage
The SVNErrorMessage class represents error and warning messages describing reasons of exceptions occurred during runtime. An error message may be of two levels:
- Error type
- Warning type
An error message may contain an error messages stack trace, what is useful for error reason investigations. Also such a message contains an error code ( {@link SVNErrorCode}) what gives an ability to find out what kind of an error it is.
Error messages may be formatted. SVNErrorMessage performs formatting with the help of the JDK's {@link MessageFormat} class. To make a formatted message, use {@link MessageFormat} parsable format patterns and provide an array of related objects when creating an SVNErrorMessage.
Error messages may be supplied within exceptions of the main exception type - {@link SVNException}. @version 1.3 @author TMate Software Ltd. @since 1.2
