Doc from tools.jackson.core.JsonParser.canReadTypeId.

Introspection method that may be called to see if the underlying data format supports some kind of Type Ids natively (many do not; for example, JSON doesn't).

Default implementation returns true; overridden by data formats that do support native Type Ids. Caller is expected to either use a non-native notation (explicit property or such), or fail, in case it cannot use native type ids.

currentLocationback to summary
public TokenStreamLocation currentLocation()

Implements abstract tools.jackson.core.JsonParser.currentLocation.

Doc from tools.jackson.core.JsonParser.currentLocation.

Method that returns location of the last processed character; 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 TokenStreamLocation#NA due to not having access to input location information (when delegating actual decoding work to other library).

Doc from tools.jackson.core.JsonParser.currentValue.

Helper method, usually equivalent to: getParsingContext().currentValue();

Note that "current value" is NOT populated (or used) by Streaming parser; it is only used by higher-level data-binding functionality. The reason it is included here is that it can be stored and accessed hierarchically, and gets passed through data-binding.

Annotations
@Override
getBigIntegerValueback to summary
public BigInteger getBigIntegerValue() throws JacksonException

Implements abstract tools.jackson.core.JsonParser.getBigIntegerValue.

Doc from tools.jackson.core.JsonParser.getBigIntegerValue.

Numeric accessor that can be called when the current token is of type JsonToken#VALUE_NUMBER_INT and it cannot be used as a Java long primitive type due to its magnitude. It can also be called for JsonToken#VALUE_NUMBER_FLOAT; if so, it is equivalent to calling getDecimalValue and then constructing a BigInteger from that value.

Annotations
@Override
getBinaryValueback to summary
public byte[] getBinaryValue(Base64Variant arg0) throws JacksonException

Implements abstract tools.jackson.core.JsonParser.getBinaryValue.

Doc from tools.jackson.core.JsonParser.getBinaryValue.

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. It works similar to getting String value via getString() and decoding result (except for decoding part), 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.

Annotations
@Override
getDecimalValueback to summary
public BigDecimal getDecimalValue() throws JacksonException

Implements abstract tools.jackson.core.JsonParser.getDecimalValue.

Doc from tools.jackson.core.JsonParser.getDecimalValue.

Numeric accessor that can be called when the current token is of type JsonToken#VALUE_NUMBER_FLOAT or JsonToken#VALUE_NUMBER_INT. No under/overflow exceptions are ever thrown.

Annotations
@Override
getDoubleValueback to summary
public double getDoubleValue() throws JacksonException

Implements abstract tools.jackson.core.JsonParser.getDoubleValue.

Doc from tools.jackson.core.JsonParser.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. It can also be called for JsonToken#VALUE_NUMBER_INT; if so, it is equivalent to calling getLongValue and then casting; except for possible overflow/underflow exception.

Note

if the value falls outside of range of Java double, a InputCoercionException will be thrown to indicate numeric overflow/underflow.

Annotations
@Override
getEmbeddedObjectback to summary
public Object getEmbeddedObject() throws JacksonException

Overrides tools.jackson.core.base.ParserMinimalBase.getEmbeddedObject.

Doc from tools.jackson.core.JsonParser.getEmbeddedObject.

Accessor that can be called if (and only if) the current token is JsonToken#VALUE_EMBEDDED_OBJECT. For other token types, null is returned.

Note

only some specialized parser implementations support embedding of objects (usually ones that are facades on top of non-streaming sources, such as object trees). One exception is access to binary content (whether via base64 encoding or not) which typically is accessible using this method, as well as getBinaryValue().

Doc from tools.jackson.core.JsonParser.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. It can also be called for JsonToken#VALUE_NUMBER_INT; if so, it is equivalent to calling getLongValue and then casting; except for possible overflow/underflow exception.

Note

if the value falls outside of range of Java float, a InputCoercionException will be thrown to indicate numeric overflow/underflow.

It can also be called for JsonToken#VALUE_NUMBER_FLOAT; if so, it is equivalent to calling getDoubleValue and then casting; except for possible overflow/underflow exception.

Note

if the resulting integer value falls outside range of Java int, a InputCoercionException may be thrown to indicate numeric overflow/underflow.

@Override
getStringCharactersback to summary
public char[] getStringCharacters() throws JacksonException

Implements abstract tools.jackson.core.JsonParser.getStringCharacters.

Doc from tools.jackson.core.JsonParser.getStringCharacters.

Method similar to getString(), but that will return underlying (unmodifiable) character array that contains textual value, instead of constructing a String object to contain this information. Note, however, that:

  • String contents are not guaranteed to start at index 0 (rather, call getStringOffset) to know the actual offset
  • Length of string contents may be less than the length of returned buffer: call getStringLength for actual length of returned content.

Note that caller MUST NOT modify the returned character array in any way -- doing so may corrupt current parser state and render parser instance useless.

The only reason to call this method (over getString()) is to avoid construction of a String object (which will make a copy of contents).

Method that can be called to check whether current token (one that was just read) has an associated type id, and if so, return it. Note that while typically caller should check with canReadTypeId first, it is not illegal to call this method even if that method returns true; but if so, it will return null.

Implements abstract tools.jackson.core.JsonParser.isNaN.

Doc from tools.jackson.core.JsonParser.isNaN.

Accessor for checking whether current token is a special "not-a-number" (NaN) token (including both "NaN" AND positive/negative infinity!). These values are not supported by all formats: JSON, for example, only supports them if JsonReadFeature#ALLOW_NON_NUMERIC_NUMBERS is enabled.

Note

in case where numeric value is outside range of requested type -- most notably java.lang.Float or java.lang.Double -- and decoding results effectively in a NaN value, this method DOES NOT return true: only explicit incoming markers do. This is because value could still be accessed as a valid BigDecimal.

Method that will skip all child tokens of an array or object token that the parser currently points to, iff stream points to JsonToken#START_OBJECT or JsonToken#START_ARRAY. If not, it will do nothing. After skipping, stream will point to matching JsonToken#END_OBJECT or JsonToken#END_ARRAY (possibly skipping nested pairs of START/END OBJECT/ARRAY tokens as well as value tokens). The idea is that after calling this method, application will call nextToken to point to the next available token, if any.

Doc from tools.jackson.core.JsonParser.streamReadContext.

Method that can be used to access current parsing context reader is in. There are 3 different types: root, array and object contexts, with slightly different available information. Contexts are hierarchically nested, and can be used for example for figuring out part of the input document that correspond to specific array or object (for highlighting purposes, or error reporting). Contexts can also be used for simple xpath-like matching of input, if so desired.

Note

method was called getParsingContext() in Jackson 2.x

public IonReader streamReadInputSource()

Implements abstract tools.jackson.core.JsonParser.streamReadInputSource.

Doc from tools.jackson.core.JsonParser.streamReadInputSource.

Method that can be used to get access to object that is used to access input being parsed; this is usually either InputStream or Reader, depending on what parser was constructed with. Note that returned value may be null in some cases; including case where parser implementation does not want to exposed raw source to caller. In cases where input has been decorated, object returned here is the decorated version; this allows some level of interaction between users of parser and decorator object.

In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.

Note

was named getInputSource() in Jackson 2.x.
