Date: 2013-07-14

## Uses of Class
org.codehaus.jackson.JsonToken

- Packages that use JsonToken
  Package | Description
  --- | ---
  org.codehaus.jackson | Main public API classes of the core streaming JSON processor: most importantly `JsonFactory` used for constructing JSON parser (`JsonParser`) and generator (`JsonParser`) instances.
  org.codehaus.jackson.impl | Parser and generator implementation classes that Jackson defines and uses.
  org.codehaus.jackson.map | Contains basic mapper (conversion) functionality that allows for converting between regular streaming json content and Java objects (beans or Tree Model: support for both is via `ObjectMapper` class, as well as convenience methods included in `JsonParser`
  org.codehaus.jackson.map.deser | Contains implementation classes of deserialization part of data binding.
  org.codehaus.jackson.node | Contains concrete `JsonNode` implementations Jackson uses for the Tree model.
  org.codehaus.jackson.smile | Package that contains experimental implementation of "Binary-Encoded JSON-Like" data format handlers (parser, generator, factory produce both, supporting constants).
  org.codehaus.jackson.util | Utility classes used by Jackson Core functionality.

- - ### Uses of JsonToken in org.codehaus.jackson

    Fields in org.codehaus.jackson declared as JsonToken
    Modifier and Type | Field and Description
    --- | ---
    `protected JsonToken` | JsonParser.`_currToken` Last token retrieved via `JsonParser.nextToken()`, if any.
    `protected JsonToken` | JsonParser.`_lastClearedToken` Last cleared token, if any: that is, value that was in effect when `JsonParser.clearCurrentToken()` was called.

    Methods in org.codehaus.jackson that return JsonToken
    Modifier and Type | Method and Description
    --- | ---
    `abstract JsonToken` | JsonNode.`asToken()` Method that can be used for efficient type detection when using stream abstraction for traversing nodes.
    `JsonToken` | JsonParser.`getCurrentToken()` Accessor to find which token parser currently points to, if any; null will be returned if none.
    `JsonToken` | JsonParser.`getLastClearedToken()` Method that can be called to get the last token that was cleared using `JsonParser.clearCurrentToken()`.
    `abstract JsonToken` | JsonParser.`nextToken()` Main iteration method, which will advance stream enough to determine type of the next token, if any.
    `JsonToken` | JsonParser.`nextValue()` Iteration method that will advance stream enough to determine type of the next token that is a value type (including JSON Array and Object start/end markers).
    `static JsonToken` | JsonToken.`valueOf(String name)` Returns the enum constant of this type with the specified name.
    `static JsonToken[]` | JsonToken.`values()` Returns an array containing the constants of this enum type, in the order they are declared.
