Java Collection source code analysis (1), java Collection source code analysis The Java Collection toolkit is located under the Java. util package and contains many common data structures, such as arrays, linked lists, stacks, que

APIs are binary-safe. All SDS APIs process the data stored in the buf array in binary mode, the program does not impose any restrictions, filters, or assumptions on the data, such as what the data is written and what the data is read. Redis uses the buf array of SDS to store binary data instead of characters. SDS is compatible with some C string functions. Ii. Linked List Keywords: Polymorphism When a list key contains a large number of elements,

of the following conditions is true: // 1) dict_can_resize true // 2) the ratio of the number of used nodes divided by the size of the hash table is greater than // dict_force_resize_ratio // call dictExpand to expand the hash table. // the size of the used nodes must be at least twice the size of the used nodes. // O (n) if (d-> ht [0]. used> = d-> ht [0]. size (dict_can_resize | d-> ht [0]. used/d-> ht [0]. size> dict_force_resize_ratio) {return dictExpand (d, d-> ht [0]. used * 2);} return

Introduction Today's content, and source analysis is irrelevant, but from the first two of the soft text, was inspired by the shallow thought (on my way to ride the Little Donkey) In writing this article, always like to ask you a few questions, why do "source code analysis.

Exploring the principle and programming implementation of the SHA-1 algorithm in Redis source codeGuide The SHA-1 algorithm is short for the first generation of "Security Hash algorithm", and is essentially a Hash algorithm. SHA standards are mainly used for digital signatures to generate message digests, which were once considered to be the successor of the MD5 algorithm. Now the SHA family has five algori

Elasticsearch provides a simple analysis of the index logic. Here we will only clarify the main context, and some details will be elaborated in future articles. If you call the elasticsearch index interface through Java APIs, you first construct a JSON string (represented as xcontent in ES, which is an abstraction of the content to be processed ), in indexrequest, specify the index to which the document will be indexed, its type, and the Document ID.
