Constructor Detail

ReaderSource

public ReaderSource(WstxInputSource parent,
                    java.lang.String fromEntity,
                    java.lang.String pubId,
                    java.lang.String sysId,
                    java.net.URL src,
                    java.io.Reader r,
                    boolean realClose,
                    int bufSize)

Method Detail

setInputOffsets

public void setInputOffsets(int proc,
                            int row,
                            int rowStart)

Method called to change the default offsets this source has. Generally done when the underlying Reader had been partially read earlier (like reading the xml declaration before starting real parsing).

initInputLocation

public void initInputLocation(WstxInputData reader)

Input location is easy to set, as we'll start from the beginning of a File.

Specified by:

initInputLocation in class BaseInputSource

getInputBufferLength

public int getInputBufferLength()

Specified by:

getInputBufferLength in class BaseInputSource

Returns:

Length of suggested input buffer (if source needs one); used for passing default buffer size down the input source line.

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.

Specified by:

readInto in class BaseInputSource

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).

Specified by:

readMore in class BaseInputSource

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Specified by:

close in class BaseInputSource

Throws:

java.io.IOException
