Class Point

  • All Implemented Interfaces:
    Parcelable


    public class Point
    extends Object
    implements Parcelable
    Point holds two integer coordinates
    • Constructor Detail

      • Point

        public Point()
      • Point

        public Point(int x,
             int y)
      • Point

        public Point(Point src)
    • Method Detail

      • set

        public void set(int x,
               int y)
        Set the point's x and y coordinates
      • negate

        public final void negate()
        Negate the point's coordinates
      • offset

        public final void offset(int dx,
                  int dy)
        Offset the point's coordinates by dx, dy
      • equals

        public final boolean equals(int x,
                     int y)
        Returns true if the point's coordinates equal (x,y)
      • equals

        public boolean equals(Object o)
        Description copied from class: Object
        Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

        The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

        The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

        Overrides:
        equals in class Object
        Parameters:
        o - the object to compare this instance with.
        Returns:
        true if the specified object is equal to this Object; false otherwise.
        See Also:
        Object.hashCode()
      • hashCode

        public int hashCode()
        Description copied from class: Object
        Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

        Note that hash values must not change over time unless information used in equals comparisons also changes.

        See Writing a correct hashCode method if you intend implementing your own hashCode method.

        Overrides:
        hashCode in class Object
        Returns:
        this object's hash code.
        See Also:
        Object.equals(java.lang.Object)
      • toString

        public String toString()
        Description copied from class: Object
        Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:
           getClass().getName() + '@' + Integer.toHexString(hashCode())

        See Writing a useful toString method if you intend implementing your own toString method.

        Overrides:
        toString in class Object
        Returns:
        a printable representation of this object.
      • describeContents

        public int describeContents()
        Parcelable interface methods
        Specified by:
        describeContents in interface Parcelable
        Returns:
        a bitmask indicating the set of special object types marshalled by the Parcelable.
      • writeToParcel

        public void writeToParcel(Parcel out,
                         int flags)
        Write this point to the specified parcel. To restore a point from a parcel, use readFromParcel()
        Specified by:
        writeToParcel in interface Parcelable
        Parameters:
        out - The parcel to write the point's coordinates into
        flags - Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
      • readFromParcel

        public void readFromParcel(Parcel in)
        Set the point's coordinates from the data stored in the specified parcel. To write a point to a parcel, call writeToParcel().
        Parameters:
        in - The parcel to read the point's coordinates from
