Class InputStreamWrapper

java.lang.Object

org.jibx.runtime.impl.InputStreamWrapper

public class InputStreamWrapper
extends Object

Wrapper for input buffer that supports multiple character encodings. This is needed because the XPP3 pull parser does not support detecting the character encoding for a document based on the content of the document. If used with a common encoding this performs the conversion to characters using an inner reader class; otherwise, this creates the appropriate reader type

Method Detail

setBuffer

public void setBuffer(IInByteBuffer buff)

Set the input buffer.

Parameters:

buff -

getBuffer

public IInByteBuffer getBuffer()

Get input buffer.

Returns:

buffer, null if none set

setEncoding

public void setEncoding(String enc)
                 throws IOException

Set encoding for stream. This call is only valid if the encoding has not been set previously, and if the encoding is a recognized type.

Parameters:

enc - character encoding used for input from stream (null if to be determined from XML input)

Throws:

IOException - if unknown encoding, or encoding already set

getReader

public Reader getReader()
                 throws IOException

Get reader for wrapped input stream. This creates and returns a reader using the appropriate encoding, if necessary reading and examining the first part of the stream (including the XML declaration, if present) to determine the encoding.

Returns:

reader

Throws:

IOException - if error reading from document or creating a reader for the encoding found

getEncoding

public String getEncoding()

Get encoding for input document. This call may not return an accurate result until after getReader() is called.

Returns:

character encoding for input document

close

public void close()
           throws IOException

Close document input. Completes reading of document input, including closing the input medium.

Throws:

IOException - on error closing document

reset

public void reset()

Reset to initial state for reuse.
