Method Summary

Modifier and Type	Method	Description
abstract JsonLocation	currentLocation()	Method that returns location of the last processed input unit (character or byte) from the input; usually for error reporting purposes.
abstract JsonLocation	currentTokenLocation()	Method that return the starting location of the current (most recently returned) token; that is, the position of the first input unit (character or byte) from input that starts the current token.
ObjectCodec	getCodec()	Accessor for ObjectCodec associated with this parser, if any.
JsonLocation	getCurrentLocation()	Deprecated.
JsonParser.NumberTypeFP	getNumberTypeFP()	JSON format does not have native information on "correct" floating-point type to use, unlike some formats (most binary formats), so it needs to indicate this as JsonParser.NumberTypeFP.UNKNOWN.
JacksonFeatureSet<StreamReadCapability>	getReadCapabilities()	Accessor for getting metadata on capabilities of this parser, based on underlying data format being read (directly or indirectly).
JsonLocation	getTokenLocation()	Deprecated.
void	setCodec(ObjectCodec c)	Setter that allows defining ObjectCodec associated with this parser, if any.

Method Detail

getCodec

public ObjectCodec getCodec()

Description copied from class: JsonParser

Accessor for ObjectCodec associated with this parser, if any. Codec is used by JsonParser.readValueAs(Class) method (and its variants).

Specified by:

getCodec in class JsonParser

Returns:

Codec assigned to this parser, if any; null if none

setCodec

public void setCodec(ObjectCodec c)

Description copied from class: JsonParser

Setter that allows defining ObjectCodec associated with this parser, if any. Codec is used by JsonParser.readValueAs(Class) method (and its variants).

Specified by:

setCodec in class JsonParser

Parameters:

c - Codec to assign, if any; null if none

getReadCapabilities

public final JacksonFeatureSet<StreamReadCapability> getReadCapabilities()

Description copied from class: JsonParser

Accessor for getting metadata on capabilities of this parser, based on underlying data format being read (directly or indirectly).

Overrides:

getReadCapabilities in class JsonParser

Returns:

Set of read capabilities for content to read via this parser

getNumberTypeFP

public JsonParser.NumberTypeFP getNumberTypeFP()
                                        throws java.io.IOException

JSON format does not have native information on "correct" floating-point type to use, unlike some formats (most binary formats), so it needs to indicate this as JsonParser.NumberTypeFP.UNKNOWN.

Overrides:

getNumberTypeFP in class JsonParser

Returns:

Natural floating-point type if known; JsonParser.NumberTypeFP.UNKNOWN for all JSON-backed parsers.

Throws:

java.io.IOException - for low-level read issues, or JsonParseException for decoding problems

currentLocation

public abstract JsonLocation currentLocation()

Description copied from class: JsonParser

Method that returns location of the last processed input unit (character or byte) from the input; usually for error reporting purposes.

Note that the location is not guaranteed to be accurate (although most implementation will try their best): some implementations may only report specific boundary locations (start or end locations of tokens) and others only return JsonLocation.NA due to not having access to input location information (when delegating actual decoding work to other library)

Overrides:

currentLocation in class JsonParser

Returns:

Location of the last processed input unit (byte or character)

currentTokenLocation

public abstract JsonLocation currentTokenLocation()

Description copied from class: JsonParser

Method that return the starting location of the current (most recently returned) token; that is, the position of the first input unit (character or byte) from input that starts the current token.

Note that the location is not guaranteed to be accurate (although most implementation will try their best): some implementations may only return JsonLocation.NA due to not having access to input location information (when delegating actual decoding work to other library)

Overrides:

currentTokenLocation in class JsonParser

Returns:

Starting location of the token parser currently points to

getCurrentLocation

@Deprecated
public final JsonLocation getCurrentLocation()

Deprecated.

Description copied from class: ParserBase

Method that returns location of the last processed character; usually for error reporting purposes

Overrides:

getCurrentLocation in class ParserBase

Returns:

Location of the last processed input unit (byte or character)

getTokenLocation

@Deprecated
public final JsonLocation getTokenLocation()

Deprecated.

Description copied from class: ParserBase

Method that return the starting location of the current token; that is, position of the first character from input that starts the current token.

Overrides:

getTokenLocation in class ParserBase

Returns:

Starting location of the token parser currently points to
