                                   IOContext context)
                            throws java.io.IOException

Throws:

java.io.IOException

Method Detail

startDocument

public void startDocument(int numVectorFields)
                   throws java.io.IOException

Description copied from class: TermVectorsWriter

Called before writing the term vectors of the document. TermVectorsWriter.startField(FieldInfo, int, boolean, boolean, boolean) will be called numVectorFields times. Note that if term vectors are enabled, this is called even if the document has no vector fields, in this case numVectorFields will be zero.

Specified by:

startDocument in class TermVectorsWriter

Throws:

java.io.IOException

startField

public void startField(FieldInfo info,
                       int numTerms,
                       boolean positions,
                       boolean offsets,
                       boolean payloads)
                throws java.io.IOException

Description copied from class: TermVectorsWriter

Called before writing the terms of the field. TermVectorsWriter.startTerm(BytesRef, int) will be called numTerms times.

Specified by:

startField in class TermVectorsWriter

Throws:

java.io.IOException

startTerm

public void startTerm(BytesRef term,
                      int freq)
               throws java.io.IOException

Description copied from class: TermVectorsWriter

Adds a term and its term frequency freq. If this field has positions and/or offsets enabled, then TermVectorsWriter.addPosition(int, int, int, BytesRef) will be called freq times respectively.

Specified by:

startTerm in class TermVectorsWriter

Throws:

java.io.IOException

addPosition

public void addPosition(int position,
                        int startOffset,
                        int endOffset,
                        BytesRef payload)
                 throws java.io.IOException

Description copied from class: TermVectorsWriter

Adds a term position and offsets

Specified by:

addPosition in class TermVectorsWriter

Throws:

java.io.IOException

finish

public void finish(FieldInfos fis,
                   int numDocs)
            throws java.io.IOException

Description copied from class: TermVectorsWriter

Called before TermVectorsWriter.close(), passing in the number of documents that were written. Note that this is intentionally redundant (equivalent to the number of calls to TermVectorsWriter.startDocument(int), but a Codec should check that this is the case to detect the JRE bug described in LUCENE-1282.

Specified by:

finish in class TermVectorsWriter

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in class TermVectorsWriter

Throws:

java.io.IOException
