- Method Detail
  - getString
```
public String getString()
```
    Description copied from interface: JsonParser
    
    Returns a String for 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 is JsonParser.Event.KEY_NAME, JsonParser.Event.VALUE_STRING, or JsonParser.Event.VALUE_NUMBER.
    
    Specified by:
    
    getString in interface JsonParser
    
    Returns:
    
    a name when the parser state is JsonParser.Event.KEY_NAME a string value when the parser state is JsonParser.Event.VALUE_STRING a number value when the parser state is JsonParser.Event.VALUE_NUMBER
  - isIntegralNumber
```
public boolean isIntegralNumber()
```
    Description copied from interface: JsonParser
    Returns true if the JSON number at the current parser state is a integral number. A BigDecimal may be used to store the value internally and this method semantics are defined using its scale(). 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:
    
    isIntegralNumber in interface JsonParser
    
    Returns:
    
    true if this number is a integral number, otherwise false
  - getInt
```
public int getInt()
```
    Description copied from interface: JsonParser
    
    Returns a JSON number as an integer. The returned value is equal to new 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 is JsonParser.Event.VALUE_NUMBER.
    
    Specified by:
    
    getInt in interface JsonParser
    
    Returns:
    
    an integer for a JSON number
    
    See Also:
    
    BigDecimal.intValue()
  - getLong
```
public long getLong()
```
    Description copied from interface: JsonParser
    
    Returns a JSON number as a long. The returned value is equal to new 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 is JsonParser.Event.VALUE_NUMBER.
    
    Specified by:
    
    getLong in interface JsonParser
    
    Returns:
    
    a long for a JSON number
    
    See Also:
    
    BigDecimal.longValue()
  - getBigDecimal
```
public BigDecimal getBigDecimal()
```
    Description copied from interface: JsonParser
    
    Returns a JSON number as a BigDecimal. The BigDecimal is created using new BigDecimal(getString()). This method should only called when the parser state is JsonParser.Event.VALUE_NUMBER.
    
    Specified by:
    
    getBigDecimal in interface JsonParser
    
    Returns:
    
    a BigDecimal for a JSON number
  - getArray
```
public JsonArray getArray()
```
    Description copied from interface: JsonParser
    
    Returns a JsonArray and advance the parser to the the corresponding END_ARRAY.
    
    Specified by:
    
    getArray in interface JsonParser
    
    Returns:
    
    the JsonArray at the current parser position
  - getObject
```
public JsonObject getObject()
```
    Description copied from interface: JsonParser
    
    Returns a JsonObject and advances the parser to the corresponding END_OBJECT.
    
    Specified by:
    
    getObject in interface JsonParser
    
    Returns:
    
    the JsonObject at the current parser position
  - getValue
```
public JsonValue getValue()
```
    Description copied from interface: JsonParser
    
    Returns a JsonValue at the current parser position. If the parser state is START_ARRAY, the behavior is the same as JsonParser.getArray(). If the parser state is START_OBJECT, the behavior is the same as JsonParser.getObject(). For all other cases, if applicable, the JSON value is read and returned.
    
    Specified by:
    
    getValue in interface JsonParser
    
    Returns:
    
    the JsonValue at the current parser position.
  - getArrayStream
```
public Stream<JsonValue> getArrayStream()
```
    Description copied from interface: JsonParser
    
    Returns a stream of the JsonArray elements. The parser state must be START_ARRAY. The elements are read lazily, on an as-needed basis, as required by the stream operations. If the stream operations do not consume all of the array elements, JsonParser.skipArray() can be used to skip the unprocessed array elements.
    
    Specified by:
    
    getArrayStream in interface JsonParser
    
    Returns:
    
    a stream of elements of the JsonArray
  - getObjectStream
```
public Stream<Map.Entry<String,JsonValue>> getObjectStream()
```
    Description copied from interface: JsonParser
    
    Returns a stream of the JsonObject's name/value pairs. The parser state must be START_OBJECT. The name/value pairs are read lazily, on an as-needed basis, as required by the stream operations. If the stream operations do not consume all of the object's name/value pairs, JsonParser.skipObject() can be used to skip the unprocessed elements.
    
    Specified by:
    
    getObjectStream in interface JsonParser
    
    Returns:
    
    a stream of name/value pairs of the JsonObject
  - getValueStream
```
public Stream<JsonValue> getValueStream()
```
    Description copied from interface: JsonParser
    
    Returns a stream of JsonValue from a sequence of JSON values. The values are read lazily, on an as-needed basis, as needed by the stream operations.
    
    Specified by:
    
    getValueStream in interface JsonParser
    
    Returns:
    
    a Stream of JsonValue
  - skipArray
```
public void skipArray()
```
    Description copied from interface: JsonParser
    
    Advance the parser to END_ARRAY. If the parser is in array context, i.e. it has previously encountered a START_ARRAY without encountering the corresponding END_ARRAY, the parser is advanced to the corresponding END_ARRAY. If the parser is not in any array context, nothing happens.
    
    Specified by:
    
    skipArray in interface JsonParser
  - skipObject
```
public void skipObject()
```
    Description copied from interface: JsonParser
    
    Advance the parser to END_OBJECT. If the parser is in object context, i.e. it has previously encountered a START_OBJECT without encountering the corresponding END_OBJECT, the parser is advanced to the corresponding END_OBJECT. If the parser is not in any object context, nothing happens.
    
    Specified by:
    
    skipObject in interface JsonParser
  - getLocation
```
public JsonLocation getLocation()
```
    Description copied from interface: JsonParser
    
    Return 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:
    
    getLocation in interface JsonParser
    
    Returns:
    
    a non-null location corresponding to the current parser state in JSON input source

public JsonLocation getLastCharLocation()
```
  - hasNext
```
public boolean hasNext()

    Description copied from interface: JsonParser
    
    Returns true if there are more parsing states. This method returns false if the parser reaches the end of the JSON text.
    
    Specified by:
    
    hasNext in interface JsonParser
    
    Returns:
    
    true if there are more parsing states.

```
    Description copied from interface: JsonParser
    
    Returns the event for the next parsing state.
    
    Specified by:
    
    next in interface JsonParser

    the event for the next parsing state
  - close
```

```
    Description copied from interface: JsonParser
    
    Closes this parser and frees any resources associated with the parser. This method closes the underlying input source.
