public final class BranchingReaderSource extends ReaderSource
Specialized input source that can "branch" input it reads; essentially both giving out read data AND also writing it out to a Writer.Currently this Reader is only used as the main-level Reader, to allow for branching of internal DTD subset to a text buffer if necessary.

readInto
public int readInto(WstxInputData reader) throws IOException, XMLStreamException
Description copied from class:WstxInputSource
Method called to read at least one more char from input source, and update input data appropriately.- Overrides:
readInto
in classReaderSource
- Returns:
- Number of characters read from the input source (at least 1), if it had any input; -1 if input source has no more input.
- Throws:
IOException
XMLStreamException
-
readMore
public boolean readMore(WstxInputData reader, int minAmount) throws IOException, XMLStreamException
Description copied from class:WstxInputSource
Method called by reader when it has to have at least specified number of consequtive input characters in its buffer, and it currently does not have. If so, it asks input source to do whatever it has to do to try to get more data, if possible (including moving stuff in input buffer if necessary and possible).- Overrides:
readMore
in classReaderSource
- Returns:
- True if input source was able to provide specific number of characters or more; false if not. In latter case, source is free to return zero or more characters any way.
- Throws:
IOException
XMLStreamException
-
startBranch
public void startBranch(TextBuffer tb, int startOffset, boolean convertLFs)
-
endBranch
public void endBranch(int endOffset)
Currently this input source does not implement branching
