Brief Introduction
In a project, you need to analyze the PHP code and separate the corresponding function calls (and the location of the source code ). Although this can also be implement
In a project, you need to analyze the PHP code to isolate the corresponding function call (and the location of the source code). While this is also possible, it is not the best way to consider both efficiency and code complexity.

As for the theoretical aspects of the said, you can view the API, now mainly give a few examples to illustrate the difference between:
Example one:
String sample1= "Ben Ben"; With a 8-space interval between Ben.
string[] split1 = Sample1.split (""); Isolate by a space
Final listFinal StringTokenizer tokens = new StringTokenizer (Sample1, "");
Results: Split1.length was 9 olines.size as 2
Explanation: If split is separated, he will save the space as a string into the array, and
If you are puzzled by the actual operations on Python lexical analysis, you can click the following article to learn about it, we hope you can implement the relevant Python lexical analysis in tokenizer under the Parser directory. h and tokenizer. cpp content.
In Python lexical analysis, tokenizer. h and tokenizer. cpp
the core class of the word breaker: Analyzer:Word breaker tokenstream: a stream that a word breaker gets when it's done processing. This stream stores the various information of the word breaker, which can be effectively obtained by tokenstream to the word-breaker unit. The following is the process of converting a file stream to a component word flow (Tokenstream)First, through the tokenizer to do word segmentation, different word breakers have differ
I found that I did not input or output the text. After one night, I finally understood it in the middle of the night:
Written in manual:
The tokenisation can be run as follows :~ /Mosesdecoder/scripts/tokenizer. Perl-l en
The mlgb write is too inaccurate (although it is accurate after careful consideration). I always thought that the '

Tokenstream extends attributesource implements closeable:Incrementtoken, end, reset, closeTokenizer directly inherits to tokenstream, and its input is a readerTokenfilter also directly inherits tokenstream, but input is a tokenstream.Tokenstreamcomponents encapsulates tokenizer and tokenfilter (or tokenizer, two members are source and sink). You can use setreader and gettokenstream to return the sink.Analyz
abstract class for decoration. It inherits component and extends the functionality of the component class from the external class. Concretedecoratora and concretedecoratorb are specific decorative classes and are responsible for implementing specific decorative duties. Let's take a look at the structure of the entire class of the Word Segmentation module:
We can see whether it is the same as the structure chart of the above modifier mode. Tokenstream is an abstract class. We should underst

The tokenizer Library provides four predefined word segmentation objects. char_delimiters_separator has been deprecated. The others are as follows:1. char_separator
Char_separator has two constructors.
1 char_separator()
Use the std: isspace () function to identify the discarded separator, and use std: ispunct () to identify the reserved separator. In addition, empty word
When compiling lexer or parser, except lexer and parser, tokenize and tokenizer often appear, basically all source code that involves lexical parsing will use tokenize.
It is named by developers who use English. Otherwise, the name may be replaced by other simple words and will not be visualized, therefore, different languages and cultures may lead to different ways of thinking. Therefore, Chinese people's ways of thinking must be different from that

Java Stream Tokenizer, streamtokenizer
Note:JAVA is generally used to solve problems using the handler class.InputBut it may time out when the time is strictly required. I encountered this problem when I solved POJ1823, and then switched to the StreamTokenizer class.Input. It seems that the latter handlesInputHigh efficiency.The following is a summary:1.

You can also get some general similarities by analogy to traditional relational databases:关系数据库 ⇒ 数据库 ⇒ 表 ⇒ 行 ⇒ 列(Columns)Elasticsearch ⇒ 索引 ⇒ 类型 ⇒ 文档 ⇒ 字段(Fields)一个Elasticsearch集群可以包含多个索引(数据
First, window installation Elasticsearch installationThe client version of Elasticsearch must be consistent with the main version of the server version.1, Java Installation "slightly" 2, Elasticsearch downloadAddress: https://www.elastic.co/downloads/past-releasesSelect the appropriate version, use elasticsearch5.4.3 download zip here3, decompression
After elasticsearch is installed, We need to configure a series of elasticsearch configurations as follows:
Cluster. Name: rmscloud
Cluster name
Node. Name: "rcnode21"
Node name
Node. Tag: "tag21"
Node label
Node. Data: True
Whether the node stores data
Index. number_of_shards: 5
Number of index shards

Elasticsearch October 2014 briefing, elasticsearch1. Elasticsearch Updates
1.1 released Kibana 4 Beta 1 and Beta 1.1
Kibana 4 is different from Kibana in layout, configuration, and bottom-layer Chart Drawing. After learning the functional requirements of many communities based on Kibana 3, Kibana's self-Kibana 2 major change resulted in the second major change made by Kibana 3. Kibana has always been commit
