CvPoint

public CvPoint(int x,
               int y)

A constructor used to create a CvPoint instance using the input parameters x and y.

参数:

x - Indicates the horizontal coordinate of a coordinate point.

y - Indicates the vertical coordinate of a coordinate point.

CvPoint

public CvPoint(CvPoint src)

A constructor used to create a CvPoint instance using the input parameter src.

参数:

src - Indicates the coordinates of a CvPoint instance.

方法详细资料

set

public void set(int inputX,
                int inputY)

Sets the horizontal and vertical coordinates of a coordinate point.

参数:

inputX - Indicates the horizontal coordinate of a coordinate point.

inputY - Indicates the vertical coordinate of a coordinate point.

从以下版本开始:

1

negate

public final void negate()

Obtains the opposite number of the horizontal and vertical coordinates.

从以下版本开始:

1

offset

public final void offset(int dx,
                         int dy)

Obtains the coordinates after the horizontal and vertical coordinates are offset.

参数:

dx - Indicates the offset of the horizontal coordinate.

dy - Indicates the offset of the vertical coordinate.

equals

public final boolean equals(int inputX,
                            int inputY)

Checks whether an input instance is equal to the current instance.

This method passes the horizontal and vertical coordinate points and checks whether their combination is equal to that of an existing instance in the class.

参数:

inputX - Indicates the horizontal coordinate of a coordinate point.

inputY - Indicates the vertical coordinate of a coordinate point.

返回:

Returns true if the input instance is equal to the current instance; returns false otherwise.

从以下版本开始:

1

equals

public boolean equals(Object object)

Checks whether an input instance is equal to the current instance.

覆盖:

equals 在类中 Object

参数:

object - Indicates the input instance.

返回:

Returns true if the input instance is equal to the current instance; returns false otherwise.

从以下版本开始:

1

Object.hashCode(), HashMap

hashCode

public int hashCode()

Calculates the hash code of the object based on the horizontal and vertical coordinates.

覆盖:

hashCode 在类中 Object

返回:

Returns the hash code.

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

toString

public String toString()

Combines the horizontal and vertical coordinates of the current instance to a character string. In this way, the current instance can be passed to other modules.

覆盖:

toString 在类中 Object

返回:

Returns a character string representing the horizontal and vertical coordinates of the current instance.

marshalling

public boolean marshalling(Parcel out)

Marshals the horizontal and vertical coordinates of the current instance.

指定者:

marshalling 在接口中 Sequenceable

参数:

out - Indicates the marshalled object to which the horizontal and vertical coordinates of the object are written.

返回:

Returns true if the marshalling is complete; returns false otherwise.

从以下版本开始:

1

unmarshalling

public boolean unmarshalling(Parcel in)

Unmarshals an object to obtain its horizontal and vertical coordinates.

指定者:

unmarshalling 在接口中 Sequenceable

参数:

in - Indicates a marshalled object used to read the horizontal and vertical coordinates of the object.

返回:

Returns true if the unmarshalling is complete; returns false otherwise.
