Class SVNErrorMessage

    java.lang.Object
      org.tmatesoft.svn.core.SVNErrorMessage

All Implemented Interfaces:
  Serializable

public class SVNErrorMessage
extends Object
implements Serializable

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 (`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 `MessageFormat` class. To make a formatted message, use `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 - `SVNException`.

  Parameters:
    `parentMessage` - a parent error description
    `relatedObjects` - objects to be formatted with `parentMessage`

    a parent error message

### isWarning

    public boolean isWarning()

    true if this error message is of type `TYPE_WARNING`} and false otherwise

### setType

    public boolean setType(int type)

  `type` must be either `TYPE_ERROR` or `TYPE_WARNING`. This method is intended for inner (within internals) purposes only and must not be used by API users.

  Parameters:
    `type` - error message type
  Returns:
    true if the type of this error message is changed, false if the type passed is not recognized and thus ignored

### getRootErrorMessage
