JSONLexer (openkit-java 3.2.0 API)

java.lang.Object
- com.dynatrace.openkit.util.json.lexer.JSONLexer

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable
```
public class JSONLexer
extends java.lang.Object
implements java.io.Closeable
```
Lexical analyzer for JSON, based on RFC 8259 (see also https://tools.ietf.org/html/rfc8259).
Unlike traditional lexers, which are normally generated, this one is implemented by hand. A normal implementation would rely on a DFA, this one encapsulates substates in subroutines.
