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.

BranchingReaderSource

public BranchingReaderSource(ReaderConfig cfg,
                             java.lang.String pubId,
                             java.lang.String sysId,

Method Detail

readInto

public int readInto(WstxInputData reader)
             throws java.io.IOException
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 class ReaderSource
Throws:
java.io.IOException

readMore

public boolean readMore(WstxInputData reader,
                        int minAmount)
                 throws java.io.IOException
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 class ReaderSource
Throws:
java.io.IOException

startBranch

public void startBranch(TextBuffer tb,
                        int startOffset,
                        boolean convertLFs)

endBranch

public void endBranch(int endOffset)
Currently this input source does not implement branching
