Method Detail

getMessage

public String getMessage()

This method returns a message indicating what went wrong, in this format: super.getMessage() + (detail == null ? "" : "; nested exception is:\n\t" + detail).

Overrides:

getMessage in class Throwable

Returns:

the chained message

getCause

public 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 Throwable

Returns:

the cause
