Method Detail

getMessage

public java.lang.String getMessage()

Overrides:

getMessage in class java.lang.Throwable

Returns:

the chained message

getCause

public java.lang.Throwable getCause()

Returns the cause of this exception. Note that this may not be the original cause, thanks to the detail field being public and non-final (yuck). However, to avoid violating the contract of Throwable.getCause(), this returns null if detail == this, as no exception can be its own cause.

Overrides:

getCause in class java.lang.Throwable

Returns:

the cause
