Field Detail

info

protected final de.smartics.exceptions.ExceptionInfo info
Reference to common exception information. Currently this is the exception identifier and the exception code.

Constructor Detail

AbstractCoreException

protected AbstractCoreException(Code code)
Constructor.

Parameters:
code - the error or exception code of the exception.
See Also:
AbstractCoreException(String, Throwable, Code)

AbstractCoreException

protected AbstractCoreException(String message,
                                Code code)
Constructor.

Parameters:
message - the detail message (which is saved for later retrieval by the Throwable.getMessage() method). Only used if there is no localized message in the bundle.
code - the error or exception code of the exception.
See Also:
AbstractCoreException(String, Throwable, Code)

AbstractCoreException

protected AbstractCoreException(Throwable cause,
                                Code code)
Constructor.

Parameters:
cause - the cause (which is saved for later retrieval by the getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
code - the error or exception code of the exception.
See Also:
AbstractCoreException(String, Throwable, Code)

AbstractCoreException

protected AbstractCoreException(String message,
                                Throwable cause,
                                Code code)
                         throws NullPointerException
Constructor.

Parameters:
message - the detail message (which is saved for later retrieval by the Throwable.getMessage() method). Only used if there is no localized message in the bundle.
cause - the cause (which is saved for later retrieval by the getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
code - the error or exception code of the exception.
Throws:
NullPointerException - if the code is null.

Method Detail

getId

public final ExceptionId<?> getId()
Description copied from interface: CoreException
Returns the unique identifier of the exception. The identifier is used to track an exception in different tiers.

This identifier must never be null.

Specified by:
getId in interface CoreException
Returns:
the unique identifier of the exception.

getCode

public final Code getCode()
Description copied from interface: CoreException
Returns the error or exception code of the exception.

This code must never be null.

Specified by:
getCode in interface CoreException
Returns:
the error or exception code of the exception.

getTime

public final Date getTime()
Description copied from interface: CoreException
Returns the time the exception has been raised. The time instance is created and stored as soon as the exception is constructed.

Specified by:
getTime in interface CoreException
Returns:
the time the exception has been raised.

getCause

public final Throwable getCause()
Description copied from interface: CoreException
Returns the cause of this throwable or null if the cause is nonexistent or unknown. (The cause is the throwable that caused this throwable to get thrown.)

This implementation returns the cause that was supplied via one of the constructors requiring a Throwable. While it is typically unnecessary to override this method, a subclass can override it to return a cause set by some other means. This is appropriate for a "legacy chained throwable" that predates the addition of chained exceptions to Throwable. Note that it is not necessary to override any of the PrintStackTrace methods, all of which invoke the getCause method to determine the cause of a throwable.

Specified by:
getCause in interface CoreException
Overrides:
getCause in class Throwable
Returns:
the cause of this throwable or null if the cause is nonexistent or unknown.

truncateCause

public final void truncateCause()
Description copied from interface: CoreException
Truncates the cause from the exception dependent on the ThrowableHandleMode set to the thread-local context. After running this method the cause will be truncate and the full stack trace will no longer be available.

Specified by:
truncateCause in interface CoreException

getClassLoader

protected final ClassLoader getClassLoader()
Returns a class loader to provide resources from the class path.

Returns:
a class loader to provide resources from the class path.

toString

public String toString()
Returns the string representation of the exception.

May be overridden by subclasses in an application (not a library) to change the string representation. Usually an implementation of CodeMessageFormatter should be set to the de.smartics.exceptions.ExceptionContext.

Overrides:
toString in class Throwable
Returns:
the string representation of the object.
