Summary

Public fields
`static final @NonNull ImmutableStrokeInputBatch`	`EMPTY` An empty `ImmutableStrokeInputBatch`.

Public methods
`@NonNull String`	`toString()`

Inherited methods

From androidx.ink.strokes.StrokeInputBatch

`final void`	`finalize()`
`final @NonNull StrokeInput`	`get(int index)` Gets the value of the i-th input.
`final long`	`getDurationMillis()` The duration between the first and last input in milliseconds.
`final int`	`@ExperimentalInkCustomBrushApi getNoiseSeed()` Returns the seed value that should be used for seeding any noise generators for brush behaviors when a full stroke is regenerated with this input batch.
`final int`	`getSize()` Number of `StrokeInput` objects in the batch.
`final float`	`getStrokeUnitLengthCm()` The physical distance in centimeters that the pointer must travel in order to produce an input motion of one stroke unit.
`final @NonNull InputToolType`	`getToolType()` How this input stream should be interpreted, as coming from a `InputToolType.MOUSE`, `InputToolType.TOUCH`, or `InputToolType.STYLUS`.
`final boolean`	`hasOrientation()` Whether all of the individual inputs have a defined value for `StrokeInput.orientationRadians`.
`final boolean`	`hasPressure()` Whether all of the individual inputs have a defined value for `StrokeInput.pressure`.
`final boolean`	`hasStrokeUnitLength()` Whether strokeUnitLengthCm has a valid value, which is something other than `StrokeInput.NO_STROKE_UNIT_LENGTH`.
`final boolean`	`hasTilt()` Whether all of the individual inputs have a defined value for `StrokeInput.tiltRadians`.
`final boolean`	`isEmpty()` `true` if there are no `StrokeInput` objects in the batch, and `false` otherwise.
`final @NonNull StrokeInput`	`populate(int index, @NonNull StrokeInput outStrokeInput)` Gets the value of the i-th input and overwrites `outStrokeInput`, which it then returns.
