- - com.fasterxml.aalto.in.ByteBasedScanner
  - - com.fasterxml.aalto.async.AsyncByteScanner
    - - com.fasterxml.aalto.async.AsyncByteArrayScanner

All Implemented Interfaces:

AsyncByteArrayFeeder, AsyncInputFeeder, XmlConsts, NamespaceContext, XMLStreamConstants
```
public class AsyncByteArrayScanner
extends AsyncByteScanner
implements AsyncByteArrayFeeder
```
This is the base class for asynchronous (non-blocking) XML scanners. Due to basic complexity of async approach, character-based doesn't make much sense, so only byte-based input is supported.

Method Summary

Methods
Modifier and Type	Method and Description
`protected boolean`	`decodeDecEntity()`
`protected int`	`decodeGeneralEntity(PName entityName)` Method that verifies that given named entity is followed by a semi-colon (meaning next byte must be available for reading); and if so, whether it is one of pre-defined general entities.
`protected boolean`	`decodeHexEntity()`
`protected int`	`decodeUtf8_2(int c)` Note: caller must guarantee enough data is available before calling the method
`protected int`	`decodeUtf8_3(int c1)` Note: caller must guarantee enough data is available before calling the method
`protected int`	`decodeUtf8_3(int c1, int c2, int c3)`
`protected int`	`decodeUtf8_4(int c)`
`protected int`	`decodeUtf8_4(int c1, int c2, int c3, int c4)`
`void`	`feedInput(byte[] buf, int start, int len)` Method that can be called to feed more data, if (and only if) `AsyncInputFeeder.needMoreInput()` returns true.
`protected void`	`finishCharacters()` This method only gets called in non-coalescing mode; and if so, needs to parse as many characters of the current text segment from the current input block as possible.
`protected int`	`finishCharactersCoalescing()` TODO: Method not yet implemented
`protected boolean`	`handleAttrValue()`
`protected int`	`handleCDataPending()`
`protected int`	`handleCommentPending()`
`protected int`	`handleDecEntityInCharacters(int ptr)`
`protected boolean`	`handleDTDInternalSubset(boolean init)`
`protected int`	`handleEntityInAttributeValue()` Method called to handle entity encountered inside attribute value.
`protected int`	`handleEntityInCharacters()` Method called to handle entity encountered inside CHARACTERS segment, when trying to complete a non-coalescing text segment.
`protected int`	`handleEntityStartingToken()` Method called when a new token (within tree) starts with an entity.
`protected int`	`handleHexEntityInCharacters(int ptr)`
`protected int`	`handleNamedEntityStartingToken()` Method called when we see an entity that is starting a new token, and part of its name has been decoded (but not all)
`protected boolean`	`handleNsDecl()`
`protected int`	`handleNumericEntityStartingToken()` Method called to handle cases where we find something other than a character entity (or one of 4 pre-defined general entities that act like character entities)
`protected boolean`	`handlePartialCR()` Method called when there is a pending \r (from past buffer), and we need to see
`protected int`	`handlePIPending()`
`protected int`	`handleStartElement()`
`protected int`	`handleStartElementStart(byte b)` Method called when '<' and (what appears to be) a name start character have been seen.
`boolean`	`needMoreInput()` Method called to check whether it is ok to feed more data: parser returns true if it has no more content to parse (and it is ok to feed more); otherwise false (and no data should yet be fed).
`int`	`nextFromProlog(boolean isProlog)`
`int`	`nextFromTree()`
`protected int`	`parseCDataContents()`
`protected int`	`parseCommentContents()`
`protected PName`	`parseEntityName()`
`protected PName`	`parseNewEntityName(byte b)`
`protected PName`	`parseNewName(byte b)`
`protected int`	`parsePIData()`
`protected PName`	`parsePName()` This method can (for now?) be shared between all Ascii-based encodings, since it only does coarse validity checking -- real checks are done in different method.
`protected boolean`	`skipCharacters()` Method that will be called to skip all possible characters from the input buffer, but without blocking.
`protected boolean`	`skipCoalescedText()` Coalescing mode is (and will) not be implemented for non-blocking parsers, so this method should never get called.
`protected void`	`skipUtf8_2(int c)`
`protected int`	`startCharacters(byte b)` Method called to initialize state for CHARACTERS event, after just a single byte has been seen.
`protected int`	`startCharactersPending()` This method gets called, if the first character of a CHARACTERS event could not be fully read (multi-byte, split over buffer boundary).
`String`	`toString()`

```
    Description copied from class: AsyncByteScanner
    
    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.
    
    Specified by:
    
    startCharacters in class AsyncByteScanner
    
    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)

```
protected int handleEntityInCharacters()
                                throws XMLStreamException
```
    Method called to handle entity encountered inside CHARACTERS segment, when trying to complete a non-coalescing text segment.
    NOTE: unlike with generic parsing of named entities, where trailing semicolon needs to be left in place, here we should just process it right away.
    
    Returns:
    Expanded (character) entity, if positive number; 0 if incomplete.

    Method that will be called to skip all possible characters from the input buffer, but without blocking. Partial characters are not to be handled (not pending input is to be added).
    
    Specified by:
    
    skipCharacters in class AsyncByteScanner

                    throws XMLStreamException
```
    This method can (for now?) be shared between all Ascii-based encodings, since it only does coarse validity checking -- real checks are done in different method.
    Some notes about assumption implementation makes:
    - Well-formed xml content can not end with a name: as such, end-of-input is an error and we can throw an exception
    Throws:
    
    XMLStreamException
  - parseNewEntityName
```
protected final PName parseNewEntityName(byte b)
                                  throws XMLStreamException
```
    Throws:
    
    XMLStreamException
  - parseEntityName
```
protected final PName parseEntityName()
                               throws XMLStreamException
```
    Throws:
    
    XMLStreamException
  - handlePartialCR
```
protected final boolean handlePartialCR()
```
    Method called when there is a pending \r (from past buffer), and we need to see
    
    Returns:
    True if the linefeed was succesfully processed (had enough input data to do that); or false if there is no data available to check this
  - decodeUtf8_2
```
protected final int decodeUtf8_2(int c)
                          throws XMLStreamException
```
    Note: caller must guarantee enough data is available before calling the method
    
    Throws:
    
    XMLStreamException
  - skipUtf8_2
```
protected final void skipUtf8_2(int c)
                         throws XMLStreamException
```
    Throws:
    
    XMLStreamException
  - decodeUtf8_3
```
protected final int decodeUtf8_3(int c1)
                          throws XMLStreamException
```
    Note: caller must guarantee enough data is available before calling the method
    
    Throws:
    
    XMLStreamException
  - decodeUtf8_3
```
protected final int decodeUtf8_3(int c1,
               int c2,
               int c3)
                          throws XMLStreamException
```
    Throws:
    
    XMLStreamException
  - decodeUtf8_4
```
protected final int decodeUtf8_4(int c)
                          throws XMLStreamException
```
    Throws:
    
    XMLStreamException
  - decodeUtf8_4
```
protected final int decodeUtf8_4(int c1,
               int c2,
               int c3,
               int c4)
                          throws XMLStreamException
```
    Returns:
    Character value minus 0x10000; this so that caller can readily expand it to actual surrogates
    
    Throws:
    
    XMLStreamException
