Package com.ctc.wstx.io
Class ReaderBootstrapper
java.lang.Object
com.ctc.wstx.io.InputBootstrapper
com.ctc.wstx.io.ReaderBootstrapper
Input bootstrap class used when input comes from a Reader; in this case,
encoding is already known, and thus encoding from XML declaration (if
any) is only double-checked, not really used.
Note: since the actual Reader to use after bootstrapping is pre-constructed, the local input buffer can (and should) be quite small.

getInstance
public static ReaderBootstrapper getInstance(String pubId, SystemId sysId, Reader r, String appEncoding) - Parameters:
r
- Eventual reader that will be reading actual content, after bootstrapping finishesappEncoding
- Encoding that application declared; may be null. If not null, will be compared to actual declaration found; and incompatibility reported as a potential (but not necessarily fatal) problem.

bootstrapInput
public Reader bootstrapInput(ReaderConfig cfg, boolean mainDoc, int xmlVersion) throws IOException, XMLStreamException Method called to do actual bootstrapping.- Specified by:
bootstrapInput
in classInputBootstrapper
- Parameters:
xmlVersion
- Optional xml version identifier of the main parsed document (if not bootstrapping the main document). Currently only relevant for checking that XML 1.0 document does not include XML 1.1 external parsed entities. If null, no checks will be done; when bootstrapping parsing of the main document, null should be passed for this argument.- Returns:
- Actual reader to use for reading xml content
- Throws:
IOException
XMLStreamException
-
getInputEncoding
Description copied from class:InputBootstrapper
Actual character encoding used by the underlying input source; may have been passed by the application, or auto-detected by byte stream boot strapper (can not be determined from a Reader source).- Specified by:
getInputEncoding
in classInputBootstrapper
- Returns:
- Input encoding in use, if it could be determined or was passed by the calling application
-
getInputTotal
public int getInputTotal()- Specified by:
getInputTotal
in classInputBootstrapper
- Returns:
- Total number of characters read from bootstrapped input (stream, reader)
