Method Detail

raise

public final RuntimeException raise()

Re-throw an InteropException as a RuntimeException, which allows throwing it without an explicit throws declaration. The method returns RuntimeException so it can be used as

try {
    ForeignAccess.sendRead(readNode, receiver, identifier);
} catch (InteropException ex) {
    throw ex.raise();
}

but the method never returns. It throws this exception internally rather than returning any value.

Returns:
