Method Details

getZeroLengthErrorBehaviour

public ZeroLengthBehaviourI.ZeroLengthErrorBehaviour getZeroLengthErrorBehaviour()

Description copied from interface: ZeroLengthBehaviourI

Gets how to respond to arguments with zero length arrays.

Specified by:

getZeroLengthErrorBehaviour in interface ZeroLengthBehaviourI

Returns:

either EXCEPTION, NAN or VALUE

setZeroLengthErrorBehaviour

public void setZeroLengthErrorBehaviour(ZeroLengthBehaviourI.ZeroLengthErrorBehaviour zeroLengthErrorBehaviour)

Description copied from interface: ZeroLengthBehaviourI

Sets how to respond to arguments with zero length arrays. Either an Exception is thrown or NaN is returned.

Specified by:

setZeroLengthErrorBehaviour in interface ZeroLengthBehaviourI

Parameters:

zeroLengthErrorBehaviour - either EXCEPTION, NAN or VALUE

getZeroLengthValue

public Object getZeroLengthValue()

Description copied from interface: ZeroLengthBehaviourI

Gets the value to be returned when a zero length array is passed as an argument and the zero length error behaviour is set to VALUE.

Specified by:

getZeroLengthValue in interface ZeroLengthBehaviourI

Returns:

the value, null by default

setZeroLengthValue

public void setZeroLengthValue(Object zeroLengthValue)

Description copied from interface: ZeroLengthBehaviourI

Sets the value to be returned when a zero length array is passed and the zero length error behaviour is set to VALUE. The ZeroLengthBehaviourI.setZeroLengthErrorBehaviour(ZeroLengthErrorBehaviour) method should be used to set the zero length error behaviour to VALUE.

Specified by:

setZeroLengthValue in interface ZeroLengthBehaviourI

Parameters:

zeroLengthValue - the value to return when a zero length array is passed

setZeroLengthBehaviourAndValue

public void setZeroLengthBehaviourAndValue(ZeroLengthBehaviourI zeroLengthHelper)

Sets the zero length error behaviour and value from another ZeroLengthBehaviourI instance.

Parameters:

zeroLengthHelper - the instance to copy from
