    • Method Detail

      • init

        public void init​(IndexOutput termsOut,
                         SegmentWriteState state)
                  throws java.io.IOException
        Description copied from class: PostingsWriterBase
        Called once after startup, before any terms have been added. Implementations typically write a header to the provided termsOut.
        Specified by:
        init in class PostingsWriterBase
        Throws:
        java.io.IOException
      • setField

        public void setField​(FieldInfo fieldInfo)
        Description copied from class: PushPostingsWriterBase
        Sets the current field for writing, and returns the fixed length of long[] metadata (which is fixed per field), called when the writing switches to another field.
        Overrides:
        setField in class PushPostingsWriterBase
      • startDoc

        public void startDoc​(int docID,
                             int termDocFreq)
                      throws java.io.IOException
        Description copied from class: PushPostingsWriterBase
        Adds a new doc in this term. freq will be -1 when term frequencies are omitted for the field.
        Specified by:
        startDoc in class PushPostingsWriterBase
        Throws:
        java.io.IOException
      • addPosition

        public void addPosition​(int position,
                                BytesRef payload,
                                int startOffset,
                                int endOffset)
                         throws java.io.IOException
        Description copied from class: PushPostingsWriterBase
        Add a new position and payload, and start/end offset. A null payload means no payload; a non-null payload with zero length also means no payload. Caller may reuse the BytesRef for the payload between calls (method must fully consume the payload). startOffset and endOffset will be -1 when offsets are not indexed.
        Specified by:
        addPosition in class PushPostingsWriterBase
        Throws:
        java.io.IOException
      • finishDoc

        public void finishDoc()
                       throws java.io.IOException
        Description copied from class: PushPostingsWriterBase
        Called when we are done adding positions and payloads for each doc.
        Specified by:
        finishDoc in class PushPostingsWriterBase
        Throws:
        java.io.IOException
      • encodeTerm

        public void encodeTerm​(DataOutput out,
                               FieldInfo fieldInfo,
                               BlockTermState _state,
                               boolean absolute)
                        throws java.io.IOException
        Description copied from class: PostingsWriterBase
        Encode metadata as long[] and byte[]. absolute controls whether current term is delta encoded according to latest term. Usually elements in longs are file pointers, so each one always increases when a new term is consumed. out is used to write generic bytes, which are not monotonic.
        Specified by:
        encodeTerm in class PostingsWriterBase
        Throws:
        java.io.IOException
