GenericWritable的序列化只是把类型在type数组里的索引放在了前面,这样就比ObjectWritable节省了很多空间,所以推荐大家使用GenericWritable 集合类型的Writable ArrayWritable和TwoDArrayWritable ArrayWritable和TwoDArrayWritable分别表示数组和二维数组的Writable类型,指定数组的类型有两种方法,构造方法里设置,或者继承于ArrayWritable,...

Undefined attributes are reserved and are set to zero.SHF_WRITE Identifies a section that should be writable during process execution. SHF_ALLOC Identifies a section that occupies memory during process execution. Some control sections do not reside in the memory image of an object file. This ...
Regardless of whether the superclass property is stored or computed, provided it is writable (a stored property or a computed property with a setter), the subclass’s override can consist of adding setter observers to this property. The overriding property’s functions may refer to — and may...
This attribute holds a dictionary containing the writable members of the underlying class or instance. Remember, these members can be attributes or methods. Each key in .__dict__ represents an attribute name. The value associated with a given key represents the value of the corresponding ...
