Class ClosingPositionBufProcessor

  • All Implemented Interfaces:
    ByteBufProcessor, ByteProcessor

    public class ClosingPositionBufProcessor
    extends AbstractStringAwareBufProcessor
    implements ByteBufProcessor
    A ByteBufProcessor to find a closing character position. Applying this to a buffer will output the position of the closing of the section, relative to that buffer's readerIndex, or -1 if the end of the section couldn't be found. Note that this processor will only work correctly if the number of opening and closing characters match up. This is typically the case when searching for open and closing {} in a streaming JSON response (in which case the constructor variant that detects JSON strings should be used). It is invoked on a ByteBuf by calling ByteBuf#forEachByte(ByteBufProcessor) methods.
