Interface GCDevicePhysicalInputStateDiff

public interface GCDevicePhysicalInputStateDiff

An object conforming to the \c GCDevicePhysicalInputStateDiff protocol contains the input state differences between the current and previous \c GCDevicePhysicalInputState objects returned from the \c -nextInputState method of \c GCDevicePhysicalInput. API-Since: 16.0

Method Summary

Modifier and Type	Method	Description
@Nullable NSEnumerator<java.lang.Object>	changedElements()	Gets an enumerator that iterates over the elements that have changed, compared the previous input state.
long	changeForElement(@NotNull GCPhysicalInputElement element)	Check if a value of \a element changed, compared the previous input state.

Method Detail

changeForElement

long changeForElement(@NotNull
                      @NotNull GCPhysicalInputElement element)

Check if a value of \a element changed, compared the previous input state.

Parameters:

element - The element to check. This may be a pointer to either the "live" element from the device's physical input, or a pointer to an element from any input state "snapshot" of the device's physical input.

changedElements

@Nullable
@Nullable NSEnumerator<java.lang.Object> changedElements()

Gets an enumerator that iterates over the elements that have changed, compared the previous input state. This method returns \c nil if the changed elements could not be determined - typically because the input state queue filled up and older input state snapshots were dropped.
