Method Detail

updateOutput

protected void updateOutput()

Description copied from class: DefaultSignalHead

Type-specific routine to handle output to the layout hardware. Does not notify listeners of changes; that's done elsewhere. Should use the following variables to determine what to send:

• mAppearance
• mLit
• mFlashOn

Specified by:

updateOutput in class DefaultSignalHead

dispose

public void dispose()

Remove references to and from this object, so that it can eventually be garbage-collected.

Specified by:

dispose in interface NamedBean

Overrides:

dispose in class AbstractNamedBean
