Constructor Detail

Switch

public Switch(IInputPin input)

Constructor. Stores the single-bit input to be used.

Parameters:

input - the single-bit input to be used

Method Detail

isOpen

public boolean isOpen()

Description copied from interface: ISwitch

Answer true if the switch is NOT pressed

Specified by:

isOpen in interface ISwitch

Returns:

true if the input is low, i.e. the switch is open

isClosed

public boolean isClosed()

Description copied from interface: ISwitch

Answer true if the switch IS pressed

Specified by:

isClosed in interface ISwitch

Returns:

true if the input is high, i.e. the switch is closed

waitForChange

public void waitForChange()

Description copied from interface: ISwitch

Block the current thread until the switch's state changes. Note that this function may use a polling implementation that prevents deep sleep. To avoid this, use EDemoBoard.waitForPinChange().

Specified by:

waitForChange in interface ISwitch
