Field Summary

Fields
Modifier and Type	Field and Description
`protected int`	`_currQuad` Bytes parsed for the current, incomplete, quad
`protected int`	`_currQuadBytes` Number of bytes pending/buffered, stored in `_currQuad`
`protected boolean`	`_elemAllNsBound`
`protected boolean`	`_elemAttrCount`
`protected PName`	`_elemAttrName`
`protected int`	`_elemAttrPtr` Pointer for the next character of currently being parsed value within attribute value buffer
`protected byte`	`_elemAttrQuote`
`protected int`	`_elemNsPtr` Pointer for the next character of currently being parsed namespace URI for the current namespace declaration
`protected boolean`	`_endOfInput` Flag that is sent when calling application indicates that there will be no more input to parse.
`protected int`	`_entityValue` Entity value accumulated so far
`protected boolean`	`_inDtdDeclaration` Flag that indicates whether we are inside a declaration during parsing of internal DTD subset.
`protected int`	`_nextEvent` Due to asynchronous nature of parsing, we may know what event we are trying to parse, even if it's not yet complete.
`protected int`	`_pendingInput` There are some multi-byte combinations that must be handled as a unit: CR+LF linefeeds, multi-byte UTF-8 characters, and multi-character end markers for comments and PIs.
`protected int`	`_quadCount` Number of complete quads parsed for current name (quads themselves are stored in `ByteBasedScanner._quadBuffer`).
`protected int`	`_state` In addition to the event type, there is need for additional state information
`protected int`	`_surroundingEvent` For token/state combinations that are 'shared' between events (or embedded in them), this is where the surrounding event state is retained.

Method Summary

Methods
Modifier and Type	Method and Description
`protected void`	`_closeSource()` Since the async scanner has no access to whatever passes content, there is no input source in same sense as with blocking scanner; and there is nothing to close.

`protected int`	`decodeCharForError(byte b)` Method called by methods when encountering a byte that can not be part of a valid character in the current context.
`void`	`endOfInput()` Method that should be called after last chunk of data to parse has been fed.

  - _nextEvent
```
protected int _nextEvent
```
    Due to asynchronous nature of parsing, we may know what event we are trying to parse, even if it's not yet complete. Type of that event is stored here.
  - _state
```
protected int _state
```
    In addition to the event type, there is need for additional state information
  - _surroundingEvent
```
protected int _surroundingEvent
```
    For token/state combinations that are 'shared' between events (or embedded in them), this is where the surrounding event state is retained.
  - _pendingInput
```
protected int _pendingInput
```
    There are some multi-byte combinations that must be handled as a unit: CR+LF linefeeds, multi-byte UTF-8 characters, and multi-character end markers for comments and PIs. Since they can be split across input buffer boundaries, first byte(s) may need to be temporarily stored.
    If so, this int will store byte(s), in little-endian format (that is, first pending byte is at 0x000000FF, second [if any] at 0x0000FF00, and third at 0x00FF0000). This can be (and is) used to figure out actual number of bytes pending, for multi-byte (UTF-8) character decoding.
    Note: it is assumed that if value is 0, there is no data. Thus, if 0 needed to be added pending, it has to be masked.
  - _endOfInput
```
protected boolean _endOfInput
```
    Flag that is sent when calling application indicates that there will be no more input to parse.
  - _quadCount
```
protected int _quadCount
```
    Number of complete quads parsed for current name (quads themselves are stored in ByteBasedScanner._quadBuffer).
  - _currQuad
```
protected int _currQuad
```
    Bytes parsed for the current, incomplete, quad
  - _currQuadBytes
```
protected int _currQuadBytes
```
    Number of bytes pending/buffered, stored in _currQuad
  - _entityValue
```
protected int _entityValue
```
    Entity value accumulated so far
  - _elemAllNsBound
```
protected boolean _elemAllNsBound

  - _elemAttrCount

  - _elemAttrQuote
```
protected byte _elemAttrQuote
```
  - _elemAttrName
```
protected PName _elemAttrName
```
  - _elemAttrPtr
```
protected int _elemAttrPtr
```
    Pointer for the next character of currently being parsed value within attribute value buffer
  - _elemNsPtr
```
protected int _elemNsPtr
```
    Pointer for the next character of currently being parsed namespace URI for the current namespace declaration
  - _inDtdDeclaration
```
protected boolean _inDtdDeclaration
```
    Flag that indicates whether we are inside a declaration during parsing of internal DTD subset.

public void endOfInput()
```
    Description copied from interface: AsyncInputFeeder
    
    Method that should be called after last chunk of data to parse has been fed. May be called regardless of what AsyncInputFeeder.needMoreInput() returns. After calling this method, no more data can be fed; and parser assumes no more data will be available.

  - _closeSource
```
protected void _closeSource()
                     throws IOException
```
    Since the async scanner has no access to whatever passes content, there is no input source in same sense as with blocking scanner; and there is nothing to close. But we can at least mark input as having ended.

    Description copied from class: XmlScanner
    
    This method is called to ensure that the current token/event has been completely parsed, such that we have all the data needed to return it (textual content, PI data, comment text etc)

  - startCharacters
```
protected abstract int startCharacters(byte b)
                                throws XMLStreamException
```
    Method called to initialize state for CHARACTERS event, after just a single byte has been seen. What needs to be done next depends on whether coalescing mode is set or not: if it is not set, just a single character needs to be decoded, after which current event will be incomplete, but defined as CHARACTERS. In coalescing mode, the whole content must be read before current event can be defined. The reason for difference is that when XMLStreamReader.next() returns, no blocking can occur when calling other methods.
    
    Returns:
    Event type detected; either CHARACTERS, if at least one full character was decoded (and can be returned), EVENT_INCOMPLETE if not (part of a multi-byte character split across input buffer boundary)

    lastQuad - Word with last 0 to 3 bytes of the PName; not included in the quad array
    lastByteCount - Number of bytes contained in lastQuad; 0 to 3.
    firstQuad - First 1 to 4 bytes of the PName (4 if length at least 4 bytes; less only if not).
    qlen - Number of quads in the array, except if less than 2 (in which case only firstQuad and lastQuad are used)
