java.lang.Objectcom.ctc.wstx.io.WstxInputData
public class WstxInputData
Base class used by readers (specifically, by
StreamScanner
, and its sub-classes)
to encapsulate input buffer portion of the class. Philosophically
this should probably be done via containment (composition), not
sub-classing but for performance reason, this "core" class is generally
extended from instead.
Main reason for the input data portion to be factored out of main class is that this way it can also be passed to nested input handling Objects, which can then manipulate input buffers of the caller, efficiently.

---|---|
static char |
CHAR_NULL
Null-character is used as return value from some method(s), since it is not a legal character in an XML document. |
static char |
CHAR_SPACE
|
static char |
INT_NULL
|
static char |
INT_SPACE
|
static int |
MAX_UNICODE_CHAR
This constant defines the highest Unicode character allowed in XML content. |
protected long |
mCurrInputProcessed
Number of characters that were contained in previous blocks (blocks that were already processed prior to the current buffer). |
protected int |
mCurrInputRow
Current row location of current point in input buffer, starting from 1 |
protected int |
mCurrInputRowStart
Current index of the first character of the current row in input buffer. |
protected char[] |
mInputBuffer
Current buffer from which data is read; generally data is read into buffer from input source, but not always (especially when using nested input contexts when expanding parsed entity references etc). |
protected int |
mInputLen
Index of character after last available one in the buffer. |
protected int |
mInputPtr
Pointer to next available character in buffer |
protected boolean |
mXml11
Flag that indicates whether XML content is to be treated as per XML 1.1 specification or not (if not, it'll use xml 1.0). |

copyBufferStateFrom(WstxInputData src)
Note: Only public due to sub-classes needing to call this on base class instance from different package (confusing?) |
static int |
findIllegalNameChar(java.lang.String name,
boolean nsAware,
boolean xml11)
Method that can be called to check whether given String contains any characters that are not legal XML names. |
static int |
findIllegalNmtokenChar(java.lang.String nmtoken,
boolean nsAware,
boolean xml11)
|
static java.lang.String |
getCharDesc(char c)
|
protected boolean |
isNameChar(char c)
Method that can be used to check whether specified character is a valid character of an XML 1.0/1.1 name as any other char than the first one; except that colon (:) is not recognized as valid here: caller has to verify it separately (since it generally affects namespace mapping of a qualified name). |
static boolean |
isNameChar(char c,
boolean nsAware,
boolean xml11)
|
protected boolean |
isNameStartChar(char c)
Method that can be used to check whether specified character is a valid first character of an XML 1.0/1.1 name; except that colon (:) is not recognized as a start char here: caller has to verify it separately (since it generally affects namespace mapping of a qualified name). |
static boolean |
