SWTError | public class SWTError extends Error (Code) | | This error is thrown whenever an unrecoverable error
occurs internally in SWT. The message text and error code
provide a further description of the problem. The exception
has a throwable field which holds the underlying
throwable that caused the problem (if this information is
available (i.e. it may be null)).
SWTErrors are thrown when something fails internally which
either leaves SWT in an unknown state (eg. the o/s call to
remove an item from a list returns an error code) or when SWT
is left in a known-to-be-unrecoverable state (eg. it runs out
of callback resources). SWTErrors should not occur in typical
programs, although "high reliability" applications should
still catch them.
This class also provides support methods used by SWT to match
error codes to the appropriate exception class (SWTError,
SWTException, or IllegalArgumentException) and to provide
human readable strings for SWT error codes.

Field Summary | |
public int | code The SWT error code, one of SWT.ERROR_*. | final static long | serialVersionUID | public Throwable | throwable The underlying throwable that caused the problem,
or null if this information is not available. |
Constructor Summary | |
public | SWTError() Constructs a new instance of this class with its
stack trace filled in. | public | SWTError(String message) Constructs a new instance of this class with its
stack trace and message filled in. | public | SWTError(int code) Constructs a new instance of this class with its
stack trace and error code filled in. | public | SWTError(int code, String message) Constructs a new instance of this class with its
stack trace, error code and message filled in. |
Method Summary | |
public Throwable | getCause() Returns the underlying throwable that caused the problem,
or null if this information is not available.
NOTE: This method overrides Throwable.getCause() that was
added to JDK1.4. | public String | getMessage() Returns the string describing this SWTError object. | public void | printStackTrace() Outputs a printable representation of this error's
stack trace on the standard error stream. |
code | public int code(Code) | | The SWT error code, one of SWT.ERROR_*.
|
serialVersionUID | final static long serialVersionUID(Code) | | |
throwable | public Throwable throwable(Code) | | The underlying throwable that caused the problem,
or null if this information is not available.
|
SWTError | public SWTError()(Code) | | Constructs a new instance of this class with its
stack trace filled in. The error code is set to an
unspecified value.
|
SWTError | public SWTError(String message)(Code) | | Constructs a new instance of this class with its
stack trace and message filled in. The error code is
set to an unspecified value. Specifying null
as the message is equivalent to specifying an empty string.
Parameters: message - the detail message for the exception |
SWTError | public SWTError(int code)(Code) | | Constructs a new instance of this class with its
stack trace and error code filled in.
Parameters: code - the SWT error code |
SWTError | public SWTError(int code, String message)(Code) | | Constructs a new instance of this class with its
stack trace, error code and message filled in.
Specifying null as the message is
equivalent to specifying an empty string.
Parameters: code - the SWT error code Parameters: message - the detail message for the exception |
getCause | public Throwable getCause()(Code) | | Returns the underlying throwable that caused the problem,
or null if this information is not available.
NOTE: This method overrides Throwable.getCause() that was
added to JDK1.4. It is necessary to override this method
in order for inherited printStackTrace() methods to work.
the underlying throwable since: 3.1 |
getMessage | public String getMessage()(Code) | | Returns the string describing this SWTError object.
It is combined with the message string of the Throwable
which caused this SWTError (if this information is available).
the error message string of this SWTError object |
printStackTrace | public void printStackTrace()(Code) | | Outputs a printable representation of this error's
stack trace on the standard error stream.
Note: printStackTrace(PrintStream) and printStackTrace(PrintWriter)
are not provided in order to maintain compatibility with CLDC.
