All Implemented Interfaces:

RDFHandler

public class LineSupplierParserContext
extends IOParserContext

Extends IOParserContext to read the input from a LineSupplier instead of an input stream. Since two batches retrieved from a LineSupplier might not be consecutive (the batch in between might be retrieved by another thread) this context in its current form is only suitable for parsing NTriples and NQuads where a triple cannot span multiple lines.

Method Details

readCodePoint

public int readCodePoint()
                  throws IOException

Description copied from class: IOParserContext

Reads the next Unicode code point.

Overrides:

readCodePoint in class IOParserContext

Returns:

the next Unicode code point, or -1 if the end of the stream has been reached.

Throws:

IOException

unread

public void unread(int theCodePoint)

Description copied from class: IOParserContext

Pushes back a single code point by copying it to the front of the buffer. After this method returns, a call to IOParserContext.readCodePoint() will return the same code point c again.

Overrides:

unread in class IOParserContext

Parameters:

theCodePoint - a single Unicode code point.

unread

public void unread(@Nonnull
 String theStr)

Description copied from class: IOParserContext

Pushes back the supplied string by copying it to the front of the buffer. After this method returns, successive calls to IOParserContext.readCodePoint() will return the code points in the supplied string again, starting at the first in the String..

Overrides:

unread in class IOParserContext

Parameters:

theStr - the string to un-read.
