LinuxComponent

public LinuxComponent(LinuxEventComponent component)

Method Detail

isRelative

public final boolean isRelative()

Description copied from interface: Component

Returns true if data returned from poll is relative to the last call, or false if data is absolute.

isAnalog

public final boolean isAnalog()

Description copied from class: AbstractComponent

Returns whether or not the axis is analog, or false if it is digital.

Specified by:

isAnalog in interface Component

Overrides:

isAnalog in class AbstractComponent

Returns:

false by default, can be overridden

poll

protected float poll()
              throws java.io.IOException

Specified by:

poll in class AbstractComponent

Throws:

java.io.IOException

convertValue

float convertValue(float value,
                 LinuxAxisDescriptor descriptor)

getDeadZone

public final float getDeadZone()

Description copied from class: AbstractComponent

Returns the suggested dead zone for this axis. Dead zone is the amount polled data can vary before considered a significant change in value. An application can safely ignore changes less than this value in the positive or negative direction.

Specified by:

getDeadZone in interface Component

Overrides:

getDeadZone in class AbstractComponent

Returns:

0.0f by default, can be overridden
