Class JSONParser

java.lang.Object

org.apache.felix.utils.json.JSONParser

public class JSONParser
extends java.lang.Object

A very small JSON parser. The JSON input is parsed into an object structure in the following way:

• Object names are represented as a String.
• String values are represented as a String.
• Numeric values without a decimal separator are represented as a Long.
• Numeric values with a decimal separator are represented as a Double.
• Boolean values are represented as a Boolean.
• Nested JSON objects are parsed into a Map<String, Object>.
• JSON lists are parsed into a List which may contain any of the above values.
