Class StreamBootstrapper

java.lang.Object

com.ctc.wstx.io.InputBootstrapper

com.ctc.wstx.io.StreamBootstrapper

public final class StreamBootstrapper
extends InputBootstrapper

Input bootstrap class used with streams, when encoding is not known (when encoding is specified by application, a reader is constructed, and then reader-based bootstrapper is used).

Method Detail

getInstance

public static StreamBootstrapper getInstance(String pubId,
                                             SystemId sysId,
                                             InputStream in)

Factory method used when the underlying data provider is an actual stream.

getInstance

public static StreamBootstrapper getInstance(String pubId,
                                             SystemId sysId,
                                             byte[] data,
                                             int start,
                                             int end)

Factory method used when the underlying data provider is a pre-allocated block source, and no stream is used. Additionally the buffer passed is not owned by the bootstrapper or Reader that is created, so it is not to be recycled.

bootstrapInput

public Reader bootstrapInput(ReaderConfig cfg,
                             boolean mainDoc,
                             int xmlVersion)
                      throws IOException,
                             XMLStreamException

Specified by:

bootstrapInput in class InputBootstrapper

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.

Throws:

IOException

XMLStreamException

getInputEncoding

public String getInputEncoding()

Since this class only gets used when encoding is not explicitly passed, need use the encoding that was auto-detected...

Specified by:

getInputEncoding in class InputBootstrapper

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 class InputBootstrapper

Returns:

Total number of characters read from bootstrapped input (stream, reader)

getInputColumn

public int getInputColumn()

Specified by:

getInputColumn in class InputBootstrapper
