getString
public java.lang.String getString()
Description copied from interface:JsonParserReturns aStringfor the name in a name/value pair, for a string value or a number value. This method should only be called when the parser state isJsonParser.Event.KEY_NAME,JsonParser.Event.VALUE_STRING, orJsonParser.Event.VALUE_NUMBER.- Specified by:
getStringin interfaceJsonParser- Returns:
- a name when the parser state is
JsonParser.Event.KEY_NAMEa string value when the parser state isJsonParser.Event.VALUE_STRINGa number value when the parser state isJsonParser.Event.VALUE_NUMBER
-
isIntegralNumber
public boolean isIntegralNumber()
Description copied from interface:JsonParserReturns true if the JSON number at the current parser state is a integral number. ABigDecimalmay be used to store the value internally and this method semantics are defined using itsscale(). If the scale is zero, then it is considered integral type. This integral type information can be used to invoke an appropriate accessor method to obtain a numeric value as in the following example:JsonParser parser = ... if (parser.isIntegralNumber()) { parser.getInt(); // or other methods to get integral value } else { parser.getBigDecimal(); }- Specified by:
isIntegralNumberin interfaceJsonParser- Returns:
- true if this number is a integral number, otherwise false
-
getInt
public int getInt()
Description copied from interface:JsonParserReturns a JSON number as an integer. The returned value is equal tonew BigDecimal(getString()).intValue(). Note that this conversion can lose information about the overall magnitude and precision of the number value as well as return a result with the opposite sign. This method should only be called when the parser state isJsonParser.Event.VALUE_NUMBER.- Specified by:
getIntin interfaceJsonParser- Returns:
- an integer for a JSON number
- See Also:
BigDecimal.intValue()
-
getLong
public long getLong()
Description copied from interface:JsonParserReturns a JSON number as a long. The returned value is equal tonew BigDecimal(getString()).longValue(). Note that this conversion can lose information about the overall magnitude and precision of the number value as well as return a result with the opposite sign. This method is only called when the parser state isJsonParser.Event.VALUE_NUMBER.- Specified by:
getLongin interfaceJsonParser- Returns:
- a long for a JSON number
- See Also:
BigDecimal.longValue()
-
getBigDecimal
public java.math.BigDecimal getBigDecimal()
Description copied from interface:JsonParserReturns a JSON number as aBigDecimal. TheBigDecimalis created usingnew BigDecimal(getString()). This method should only called when the parser state isJsonParser.Event.VALUE_NUMBER.- Specified by:
getBigDecimalin interfaceJsonParser- Returns:
- a
BigDecimalfor a JSON number
-
getLocation
public JsonLocation getLocation()
Description copied from interface:JsonParserReturn the location that corresponds to the parser's current state in the JSON input source. The location information is only valid in the current parser state (or until the parser is advanced to a next state).- Specified by:
getLocationin interfaceJsonParser- Returns:
- a non-null location corresponding to the current parser state in JSON input source
-
hasNext
public boolean hasNext()
Description copied from interface:JsonParserReturnstrueif there are more parsing states. This method returnsfalseif the parser reaches the end of the JSON text.- Specified by:
hasNextin interfaceJsonParser- Returns:
trueif there are more parsing states.
-
next
public JsonParser.Event next()
Description copied from interface:JsonParserReturns the event for the next parsing state.- Specified by:
nextin interfaceJsonParser- Returns:
- the event for the next parsing state
-
transition
private void transition()
-
close
public void close()
Description copied from interface:JsonParserCloses this parser and frees any resources associated with the parser. This method closes the underlying input source.- Specified by:
closein interfacejava.lang.AutoCloseable- Specified by:
closein interfacejava.io.Closeable- Specified by:
closein interfaceJsonParser
-
skipObject
public void skipObject()
Description copied from interface:JsonParserAdvance the parser toEND_OBJECT. If the parser is in object context, i.e. it has previously encountered aSTART_OBJECTwithout encountering the correspondingEND_OBJECT, the parser is advanced to the correspondingEND_OBJECT. If the parser is not in any object context, nothing happens.- Specified by:
skipObjectin interfaceJsonParser
-
skipArray
public void skipArray()
Description copied from interface:JsonParserAdvance the parser toEND_ARRAY. If the parser is in array context, i.e. it has previously encountered aSTART_ARRAYwithout encountering the correspondingEND_ARRAY, the parser is advanced to the correspondingEND_ARRAY. If the parser is not in any array context, nothing happens.- Specified by:
skipArrayin interfaceJsonParser
