java.lang.Objectjava.io.Reader
com.ctc.wstx.io.UTF32Reader
public final class UTF32Reader
Since JDK does not come with UTF-32/UCS-4, let's implement a simple decoder to use.
Field Summary | |
---|---|
protected static char |
CONVERT_LSEP_TO
In xml 1.1, LSEP bit like \n, or \r. |
protected static char |
CONVERT_NEL_TO
In xml 1.1, NEL (0x85) behaves much the way \n does (can be follow \r as part of the linefeed |

void |
close()
|
void |
freeBuffers()
This method should be called along with (or instead of) normal close. |
int |
read()
Although this method is implemented by the base class, AND it should never be called by Woodstox code, let's still implement it bit more efficiently just in case |

protected void |
reportBounds(char[] cbuf,

|
protected void |
reportInvalidXml11(int value,
int bytePos,
int charPos)
|
protected void |
reportStrangeStream()
|
void |
setXmlCompliancy(int xmlVersion)
Method that can be called to indicate the xml conformance used when reading content using this reader. |
