```
@JsType(isNative=true,
        name="Touch",
        namespace="<global>")
public final class BaseTouch
extends Object
```
Represents a single contact point on a touch-sensitive device
The contact point is commonly a finger or stylus and the device may be a touchscreen or trackpad.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`double`	`getClientX()` Returns the X coordinate of the touch point relative to the left edge of the browser viewport, not including any scroll offset.
`double`	`getClientY()` Returns the Y coordinate of the touch point relative to the top edge of the browser viewport, not including any scroll offset.
`double`	`getForce()` Returns the amount of pressure being applied to the surface by the user, as a double between 0.0 (no pressure) and 1.0 (maximum pressure).
`int`	`getIdentifier()` Returns a unique identifier for this touch object. A given touch point (say, by a finger) will have the same identifier for the duration of its movement around the surface. This lets you ensure that you're tracking the same touch all the time.
`double`	`getPageX()` Returns the X coordinate of the touch point relative to the left edge of the document. Unlike clientX, this value includes the horizontal scroll offset, if any.
`double`	`getPageY()` Returns the Y coordinate of the touch point relative to the top of the document. Unlike clientY, this value includes the vertical scroll offset, if any.
`double`	`getRadiusX()` Returns the X radius of the ellipse that most closely circumscribes the area of contact with the screen. The value is in pixels of the same scale as screenX.
`double`	`getRadiusY()` Returns the Y radius of the ellipse that most closely circumscribes the area of contact with the screen. The value is in pixels of the same scale as screenY.
`double`	`getRotationAngle()` Returns the angle (in degrees) that the ellipse described by radiusX and radiusY must be rotated, clockwise, to most accurately cover the area of contact between the user and the surface.
`double`	`getScreenX()` Returns the X coordinate of the touch point relative to the left edge of the screen.
`double`	`getScreenY()` Returns the Y coordinate of the touch point relative to the top edge of the screen.
`BaseEventTarget`	`getTarget()` Returns the element on which the touch point started when it was first placed on the surface, even if the touch point has since moved outside the interactive area of that element or even been removed from the document.

  - getRadiusY
```
@JsProperty
public double getRadiusY()
```
    Returns the Y radius of the ellipse that most closely circumscribes the area of contact with the screen.
    The value is in pixels of the same scale as screenY.
    
    Returns:
    
    the Y radius of the ellipse that most closely circumscribes the area of contact with the screen
  - getRotationAngle
```
@JsProperty
public double getRotationAngle()
```

    Returns:
    
    the angle (in degrees) that the ellipse described by radiusX and radiusY must be rotated, clockwise, to most accurately cover the area of contact between the user and the surface
  - getScreenX
```
@JsProperty
public double getScreenX()
```
    Returns the X coordinate of the touch point relative to the left edge of the screen.

  - getTarget
```
@JsProperty
public BaseEventTarget getTarget()
```
    Returns the element on which the touch point started when it was first placed on the surface, even if the touch point has since moved outside the interactive area of that element or even been removed from the document.
