Constructor

Common Methods

Public intDescribeContents()

Describes various objects with special meanings that are included in the Parcelable configuration.

Return Value

A single bit mask describes the settings of special types of Parcelable objects.

 

Public booleanEquals(Object o)

Compares the instances of the specified object and returns whether they are equal. To ensure their equality, parameter o must represent the same object, which serves as a constant for comparing class dependencies. It is usually agreed that the comparison should be self-inverse, symmetric, and transmitted. In addition, there is no object reference unless null is equal to null.

Returns true by default only when this = o. If you want to implement your own equals method, see compile a correct equals method.

Equals andHashCode ()The General Convention of the method is that if any two objects are equal, true is returned, and the hashCode () of the two objects must return the same value. This indicates that the subclass object is usually overwritten by two methods or both methods.

Parameters

O objects compared by this instance

Return Value

If the specified object is equal to this object, true is returned. Otherwise, false is returned.

 

Public intHashCode()

Returns an integer Hash code of the current object. By convention, any twoEquals (Object)The object that returns true must return the same hash value. This indicates that the subclass object is usually overwritten by two methods or both methods.

Note that the hash value does not change with time unless the equals comparison changes.

If you want to implement your own hashCode method, see compile a correct hashCode method.

Return Value

The hash value of the object.

 

Public StringToString()

Returns a simple and understandable second-rate information of an object. We encourage you to rewrite this method and provide implementations that take into account types and data. The default implementation is equivalent to the following expressions:

GetClass (). getName () + '@' + Integer. toHexString (hashCode ())

If you want to implement your own toString method, see compile a correct toString method.

Return Value

A printable string representing this object

 

Public voidWriteToParcel(Parcel dest, int flags)

Write this object to Parcel

Parameters

The Parcel object to which dest should be written

The additional flags on how the object should be written. It may be 0 orPARCELABLE_WRITE_RETURN_VALUE.
