Class JulieXMLBuffer

java.lang.Object

de.julielab.xml.JulieXMLBuffer

All Implemented Interfaces:

com.ximpleware.extended.IByteBuffer

public class JulieXMLBuffer
extends Object
implements com.ximpleware.extended.IByteBuffer

Copied from the original XMLBuffer in VTD XML version 2.10. Added the "getFragment(long, long)" method which just does what seemingly "getBytes" was meant for but not yet implemented.

Method Detail

readFile

public void readFile(String fileName)
              throws IOException,
                     com.ximpleware.extended.ParseExceptionHuge

JULIE Lab adopted version of the method. Does support GZIP files. GZIP files must end with ".gz" or ".gzip" in order to be recognized.

Parameters:

fileName -

Throws:

IOException

com.ximpleware.ParseException

com.ximpleware.extended.ParseExceptionHuge

byteAt

public final byte byteAt(long index)

Specified by:

byteAt in interface com.ximpleware.extended.IByteBuffer

getBytes

public byte[] getBytes(int offset,
                       int len)

Return a byte array filled with content from underlying byte storage.

Specified by:

getBytes in interface com.ximpleware.extended.IByteBuffer

Parameters:

offset - int bytes offset (not UTF char unit)

len - int

Returns:

byte[]

length

public long length()

Total size in terms of # of bytes.

Specified by:

length in interface com.ximpleware.extended.IByteBuffer

Returns:

int

getBytes

public byte[] getBytes()

Specified by:

getBytes in interface com.ximpleware.extended.IByteBuffer

writeToFileOutputStream

public void writeToFileOutputStream(FileOutputStream ost,
                                    long os,
                                    long len)
                             throws IOException

Specified by:

writeToFileOutputStream in interface com.ximpleware.extended.IByteBuffer

Throws:

IOException

writeToOutputStream

public void writeToOutputStream(OutputStream ost,
                                long os,
                                long len)
                         throws IOException

Convenience JULIE Lab method. It's basically a copy of writeToFileOutputStream(java.io.FileOutputStream, long, long) but allows any kind of output stream as first parameter.

Parameters:

ost - Some OutputStream to write the specified XML buffer portion to.

os - The offset, in bytes, to write to ost.

len - The number of bytes to write, beginning at offset.

Throws:

IOException - If writing to the OutputStream fails.

getFragment

public byte[] getFragment(long os,
                          long len)
                   throws IOException

Convenience JULIE Lab method. It uses writeToOutputStream(OutputStream, long, long) with a ByteArrayOutputStream to return the specified buffer portion as a byte array.

Parameters:

os - Offset of the XML buffer to begin extraction, in bytes.

len - Number of bytes to extract.

Returns:

The bytes extracted from the XML buffer.

Throws:

IOException - If writing to the internal ByteArrayOutputStream fails.

close

public void close()

Specified by:

close in interface com.ximpleware.extended.IByteBuffer
