 * Provides the location information of a JSON event in an input source. The

For example, if a * {@code JsonParser} is created using * {@link javax.json.JsonArray JsonArray} input source, all the methods in * this class return -1. * * @author Jitendra Kotamraju * @see JsonParser * @see JsonParsingException */ public interface JsonLocation { /** * Return the line number for the current JSON event in the input source. * * @return the line number or -1 if none is available */ long getLineNumber(); /** * Return the column number for the current JSON event in the input source. * * @return the column number or -1 if none is available */ long getColumnNumber(); /** * Return the stream offset into the input source this location * is pointing to. If the input source is a file or a byte stream then * this is the byte offset into that stream, but if the input source is * a character media then the offset is the character offset. * Returns -1 if there is no offset available. * * @return the offset of input source stream, or -1 if there is * no offset available */ long getStreamOffset(); }
