所有已实现的接口:

Sequenceable

public class Insets
extends Object
implements Sequenceable

Provides a wrapper class representing the offsets for the left, top, right, and bottom bounds of a rectangle.

A positive value indicates that the bound approaches the rectangle center, while a negative value indicates that the bound moves away from the rectangle center.

hasFileDescriptor

public boolean hasFileDescriptor()

从接口复制的说明: Sequenceable

Checks whether the implementation class of this Sequenceable contains FileDescriptor object data.

If the custom Sequenceable class contains any FileDescriptor data, you should override this method. This method return false by default.

指定者:

hasFileDescriptor 在接口中 Sequenceable

返回:

Returns true if it contains FileDescriptor data; returns false otherwise.

marshalling

public boolean marshalling(Parcel parcel)

从接口复制的说明: Sequenceable

Marshals this Sequenceable object into a Parcel.

指定者:

marshalling 在接口中 Sequenceable

参数:

parcel - Indicates the Parcel object to which the Sequenceable object will be marshaled..

返回:

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

unmarshalling

public boolean unmarshalling(Parcel parcel)

从接口复制的说明: Sequenceable

Unmarshals this Sequenceable object from a Parcel.

指定者:

unmarshalling 在接口中 Sequenceable

参数:

parcel - Indicates the Parcel object into which the Sequenceable object has been marshaled.

返回:

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