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.
Method Summary |
void |
endBranch(int endOffset)
Currently this input source does not implement branching |

readInto(WstxInputData reader)
Method called to read at least one more char from input source, and
update input data appropriately. |
boolean |
readMore(WstxInputData reader,
int minAmount)
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. |

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
- 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:
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
- 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:
java.io.IOException

public void endBranch(int endOffset)
