Class Overview
Enumeration for basic token types used for returning results of parsing JSON content.
Summary
| Enum Values | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| JsonToken | END_ARRAY | START_OBJECT is returned when encountering ']' which signals ending of an Array value | |||||||||
| JsonToken | END_OBJECT | START_OBJECT is returned when encountering '}' which signals ending of an Object value | |||||||||
| JsonToken | FIELD_NAME | FIELD_NAME is returned when a String token is encountered as a field name (same lexical value, different function) | |||||||||
| JsonToken | NOT_AVAILABLE | NOT_AVAILABLE can be returned if JsonParser
implementation can not currently return the requested
token (usually next one), or even if any will be
available, but that may be able to determine this in
future. |
|||||||||
| JsonToken | START_ARRAY | START_OBJECT is returned when encountering '[' which signals starting of an Array value | |||||||||
| JsonToken | START_OBJECT | START_OBJECT is returned when encountering '{' which signals starting of an Object value. | |||||||||
| JsonToken | VALUE_EMBEDDED_OBJECT | Placeholder token returned when the input source has a concept
of embedded Object that are not accessible as usual structure
(of starting with START_OBJECT, having values, ending with
END_OBJECT), but as "raw" objects. |
|||||||||
| JsonToken | VALUE_FALSE | VALUE_FALSE is returned when encountering literal "false" in value context | |||||||||
| JsonToken | VALUE_NULL | VALUE_NULL is returned when encountering literal "null" in value context | |||||||||
| JsonToken | VALUE_NUMBER_FLOAT | VALUE_NUMBER_INT is returned when a numeric token other that is not an integer is encountered: that is, a number that does have floating point or exponent marker in it, in addition to one or more digits. | |||||||||
| JsonToken | VALUE_NUMBER_INT | VALUE_NUMBER_INT is returned when an integer numeric token is encountered in value context: that is, a number that does not have floating point or exponent marker in it (consists only of an optional sign, followed by one or more digits) | |||||||||
| JsonToken | VALUE_STRING | VALUE_STRING is returned when a String token is encountered in value context (array element, field value, or root-level stand-alone value) | |||||||||
| JsonToken | VALUE_TRUE | VALUE_TRUE is returned when encountering literal "true" in value context | |||||||||

Enum Values
public static final JsonToken END_ARRAY
START_OBJECT is returned when encountering ']' which signals ending of an Array value
public static final JsonToken END_OBJECT
START_OBJECT is returned when encountering '}' which signals ending of an Object value
public static final JsonToken FIELD_NAME
FIELD_NAME is returned when a String token is encountered as a field name (same lexical value, different function)
public static final JsonToken NOT_AVAILABLE
NOT_AVAILABLE can be returned if JsonParser
implementation can not currently return the requested
token (usually next one), or even if any will be
available, but that may be able to determine this in
future. This is the case with non-blocking parsers --
they can not block to wait for more data to parse and
must return something.
public static final JsonToken START_ARRAY
START_OBJECT is returned when encountering '[' which signals starting of an Array value
public static final JsonToken START_OBJECT
START_OBJECT is returned when encountering '{' which signals starting of an Object value.
public static final JsonToken VALUE_EMBEDDED_OBJECT
Placeholder token returned when the input source has a concept
of embedded Object that are not accessible as usual structure
(of starting with START_OBJECT, having values, ending with
END_OBJECT), but as "raw" objects.
Note: this token is never returned by regular JSON readers, but
only by readers that expose other kinds of source (like
JsonNode-based JSON trees, Maps, Lists and such).
public static final JsonToken VALUE_FALSE
VALUE_FALSE is returned when encountering literal "false" in value context
public static final JsonToken VALUE_NULL
VALUE_NULL is returned when encountering literal "null" in value context
public static final JsonToken VALUE_NUMBER_FLOAT
VALUE_NUMBER_INT is returned when a numeric token other that is not an integer is encountered: that is, a number that does have floating point or exponent marker in it, in addition to one or more digits.
public static final JsonToken VALUE_NUMBER_INT
VALUE_NUMBER_INT is returned when an integer numeric token is encountered in value context: that is, a number that does not have floating point or exponent marker in it (consists only of an optional sign, followed by one or more digits)
public static final JsonToken VALUE_STRING
VALUE_STRING is returned when a String token is encountered in value context (array element, field value, or root-level stand-alone value)
public static final JsonToken VALUE_TRUE
VALUE_TRUE is returned when encountering literal "true" in value context
Public Methods
public byte[] asByteArray ()
public char[] asCharArray ()
public boolean isNumeric ()
public boolean isScalarValue ()
Method that can be used to check whether this token represents a valid non-structured value. This means all tokens other than Object/Array start/end markers all field names.
