MeteringRectangle

METERING_WEIGHT_DONT_CARE

int METERING_WEIGHT_DONT_CARE

Weights set to this value will cause the camera device to ignore this rectangle. If all metering rectangles are weighed with 0, the camera device will choose its own metering rectangles.

Constant Value: 0 (0x00000000)

METERING_WEIGHT_MAX

int METERING_WEIGHT_MAX

The maximum value of valid metering weight.

Constant Value: 1000 (0x000003e8)

METERING_WEIGHT_MIN

int METERING_WEIGHT_MIN

The minimum value of valid metering weight.

Constant Value: 0 (0x00000000)

MeteringRectangle

MeteringRectangle (int x, 
                int y, 
                int width, 
                int height, 
                int meteringWeight)

Create a new metering rectangle.

MeteringRectangle

MeteringRectangle (Point xy, 
                Size dimensions, 
                int meteringWeight)

Create a new metering rectangle.

The point xy's data is copied; the reference is not retained.

MeteringRectangle

MeteringRectangle (Rect rect, 
                int meteringWeight)

Create a new metering rectangle.

The rectangle data is copied; the reference is not retained.

equals

boolean equals (Object other)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

equals

boolean equals (MeteringRectangle other)

Compare two metering rectangles to see if they are equal. Two weighted rectangles are only considered equal if each of their components (x, y, width, height, weight) is respectively equal.

getHeight

int getHeight ()

Return the height of the rectangle.

getMeteringWeight

int getMeteringWeight ()

Return the metering weight of the rectangle.

getRect

Rect getRect ()

Convenience method to create a Rect from this metering rectangle.

This strips away the weight from the rectangle.

getSize

Size getSize ()

Convenience method to create the size from this metering rectangle.

This strips away the X,Y,weight from the rectangle.

getUpperLeftPoint

Point getUpperLeftPoint ()

Convenience method to create the upper-left (X,Y) coordinate as a Point.

getWidth

int getWidth ()

Return the width of the rectangle.

getX

int getX ()

Return the X coordinate of the left side of the rectangle.

getY

int getY ()

Return the Y coordinate of the upper side of the rectangle.

hashCode

int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java^TM programming language.)

toString

String toString ()

Return the metering rectangle as a string representation "(x:%d, y:%d, w:%d, h:%d, wt:%d)" where each %d respectively represents the x, y, width, height, and weight points.
