JsonParser
implementations. Contains most common things that are independent
of actual underlying input source.JsonParser.Feature, JsonParser.NumberType
Modifier and Type | Method and Description |
---|---|
ByteArrayBuilder |
_getByteArrayBuilder() |
void |
close()
Closes the parser so that no further iteration or data access
can be made; will also close the underlying input source
if parser either owns the input source, or feature
JsonParser.Feature.AUTO_CLOSE_SOURCE is enabled. |
JsonParser |
disable(JsonParser.Feature f)
Method for disabling specified feature
(check
JsonParser.Feature for list of features) |
JsonParser |
enable(JsonParser.Feature f)
Method for enabling specified parser feature
(check
JsonParser.Feature for list of features) |
java.math.BigInteger |
getBigIntegerValue()
Numeric accessor that can be called when the current
token is of type
JsonToken.VALUE_NUMBER_INT and
it can not be used as a Java long primitive type due to its
magnitude. |
byte[] |
getBinaryValue(Base64Variant variant)
Method that can be used to read (and consume -- results
may not be accessible using other methods after the call)
base64-encoded binary data
included in the current textual JSON value.
|
JsonLocation |
getCurrentLocation()
Method that returns location of the last processed character;
usually for error reporting purposes
|
java.lang.String |
getCurrentName()
Method that can be called to get the name associated with
the current event.
|
java.lang.Object |
getCurrentValue()
Alias for
JsonParser.currentValue() , to be deprecated in later
Jackson 2.x versions (and removed from Jackson 3.0). |
java.math.BigDecimal |
getDecimalValue()
Numeric accessor that can be called when the current
token is of type
JsonToken.VALUE_NUMBER_FLOAT or
JsonToken.VALUE_NUMBER_INT . |
double |
getDoubleValue()
Numeric accessor that can be called when the current
token is of type
JsonToken.VALUE_NUMBER_FLOAT and
it can be expressed as a Java double primitive type. |
float |
getFloatValue()
Numeric accessor that can be called when the current
token is of type
JsonToken.VALUE_NUMBER_FLOAT and
it can be expressed as a Java float primitive type. |
int |
getIntValue()
Numeric accessor that can be called when the current
token is of type
JsonToken.VALUE_NUMBER_INT and
it can be expressed as a value of Java int primitive type. |
long |
getLongValue()
Numeric accessor that can be called when the current
token is of type
JsonToken.VALUE_NUMBER_INT and
it can be expressed as a Java long primitive type. |
JsonParser.NumberType |
getNumberType()
If current token is of type
JsonToken.VALUE_NUMBER_INT or
JsonToken.VALUE_NUMBER_FLOAT , returns
one of JsonParser.NumberType constants; otherwise returns null. |
java.lang.Number |
getNumberValue()
Generic number value accessor method that will work for
all kinds of numeric values.
|
java.lang.Number |
getNumberValueExact()
Method similar to
JsonParser.getNumberValue() with the difference that
for floating-point numbers value returned may be BigDecimal
if the underlying format does not store floating-point numbers using
native representation: for example, textual formats represent numbers
as Strings (which are 10-based), and conversion to Double
is potentially lossy operation. |
JsonReadContext |
getParsingContext()
Method that can be used to access current parsing context reader
is in.
|
long |
getTokenCharacterOffset() |
int |
getTokenColumnNr() |
int |
getTokenLineNr() |
JsonLocation |
getTokenLocation()
Method that return the starting location of the current
token; that is, position of the first character from input
that starts the current token.
|
boolean |
hasTextCharacters()
Method that can be used to determine whether calling of
JsonParser.getTextCharacters() would be the most efficient
way to access textual content for the event parser currently
points to. |
boolean |
isClosed()
Method that can be called to determine whether this parser
is closed or not.
|
boolean |
isNaN()
Access for checking whether current token is a numeric value token, but
one that is of "not-a-number" (NaN) variety (including both "NaN" AND
positive/negative infinity!): not supported by all formats,
but often supported for
JsonToken.VALUE_NUMBER_FLOAT . |
void |
overrideCurrentName(java.lang.String name)
Method that can be used to change what is considered to be
the current (field) name.
|
JsonParser |
overrideStdFeatures(int values,
int mask)
Bulk set method for (re)setting states of features specified by
mask . |
void |
setCurrentValue(java.lang.Object v)
Alias for
JsonParser.assignCurrentValue(java.lang.Object) , to be deprecated in later
Jackson 2.x versions (and removed from Jackson 3.0). |
JsonParser |
setFeatureMask(int newMask)
Deprecated.
|

version()
Accessor for getting version of the core package, given a parser instance.

Whether parser owns the input source depends on factory
method that was used to construct instance (so check
JsonFactory
for details,
but the general
idea is that if caller passes in closable resource (such
as InputStream
or Reader
) parser does NOT
own the source; but if it passes a reference (such as
File
or URL
and creates
stream or reader it does own them.close

JsonParser.getTextCharacters()
would be the most efficient
way to access textual content for the event parser currently
points to.
Default implementation simply returns false since only actual implementation class has knowledge of its internal buffering state. Implementations are strongly encouraged to properly override this method, to allow efficient copying of content by other code.

but should be significantly more performant.
Note that non-decoded textual contents of the current token are not guaranteed to be accessible after this method is called. Current implementation, for example, clears up textual content during decoding. Decoded binary content, however, will be retained until parser is advanced to the next event.
