public Version version()

    Description copied from class: JsonParser
    
    Accessor for getting version of the core package, given a parser instance. Left for sub-classes to implement.

    version in interface Versioned
    
    Specified by:

  - getCurrentName
```
public String getCurrentName()
                      throws IOException
```
    Method that can be called to get the name associated with the current event.
    
    Specified by:
    
    getCurrentName in class ParserMinimalBase
    
    Throws:
    
    IOException
  - overrideCurrentName
```
public void overrideCurrentName(String name)
```
    Description copied from class: JsonParser
    
    Method that can be used to change what is considered to be the current (field) name. May be needed to support non-JSON data formats or unusual binding conventions; not needed for typical processing.
    Note that use of this method should only be done as sort of last resort, as it is a work-around for regular operation.
    
    Specified by:
    
    overrideCurrentName in class ParserMinimalBase
    
    Parameters:
    name - Name to use as the current name; may be null.
  - close
```
public void close()
           throws IOException
```
    Description copied from class: JsonParser
    
    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. 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.
    
    Specified by:
    
    close in interface Closeable
    
    Specified by:
    
    close in interface AutoCloseable

    close in class ParserMinimalBase
    
    Throws:
    
    IOException
  - isClosed
```
public boolean isClosed()
```
    Description copied from class: JsonParser
    
    Method that can be called to determine whether this parser is closed or not. If it is closed, no new tokens can be retrieved by calling JsonParser.nextToken() (and the underlying stream may be closed). Closing may be due to an explicit call to JsonParser.close() or because parser has encountered end of input.
    
    Specified by:
    
    isClosed in class ParserMinimalBase
  - getParsingContext
```
public JsonReadContext getParsingContext()
```
    Description copied from class: JsonParser
    
    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.
    
    Specified by:
    
    getParsingContext in class ParserMinimalBase
  - getTokenLocation
```
public 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.
    
    Specified by:
    
    getTokenLocation in class JsonParser
  - getCurrentLocation
```
public JsonLocation getCurrentLocation()
```
    Method that returns location of the last processed character; usually for error reporting purposes
    
    Specified by:
    
    getCurrentLocation in class JsonParser
  - hasTextCharacters
```
public boolean hasTextCharacters()
```
    Description copied from class: JsonParser
    
    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.
    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.
    
    Specified by:
    
    hasTextCharacters in class ParserMinimalBase
    
    Returns:
    True if parser currently has character array that can be efficiently returned via JsonParser.getTextCharacters(); false means that it may or may not exist
  - getEmbeddedObject
```
public Object getEmbeddedObject()
                         throws IOException
```
    Description copied from class: JsonParser
    
    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).
    
    Specified by:

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

    Description copied from class: JsonParser
    
    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 JsonParser.getLongValue() and then casting; except for possible overflow/underflow exception.
    Note: if the value falls outside of range of Java float, a JsonParseException will be thrown to indicate numeric overflow/underflow.

  - _parseNumericValue
```
protected void _parseNumericValue(int expType)
                           throws IOException
```
    Method that will parse actual numeric value out of a syntactically valid number value. Type it will parse into depends on whether it is a floating point number, as well as its magnitude: smallest legal type (of ones available) is used for efficiency.
    
    Parameters:
    expType - Numeric type that we will immediately need, if any; mostly necessary to optimize handling of floating point numbers
