Method Detail

seek

final void seek(TermInfo ti)
         throws IOException

Overrides:

seek in class SegmentTermDocs

Throws:

IOException

close

public final void close()
                 throws IOException

Description copied from interface: TermDocs

Frees associated resources.

Specified by:

close in interface TermDocs

Overrides:

close in class SegmentTermDocs

Throws:

IOException

nextPosition

public final int nextPosition()
                       throws IOException

Description copied from interface: TermPositions

Returns next position in the current document. It is an error to call this more than TermDocs.freq() times without calling TermDocs.next()

This is invalid until TermDocs.next() is called for the first time.

Specified by:

nextPosition in interface TermPositions

Throws:

IOException

skippingDoc

protected final void skippingDoc()
                          throws IOException

Overrides:

skippingDoc in class SegmentTermDocs

Throws:

IOException

next

public final boolean next()
                   throws IOException

Description copied from interface: TermDocs

Moves to the next pair in the enumeration.

Returns true iff there is such a next pair in the enumeration.

Specified by:

next in interface TermDocs

Overrides:

next in class SegmentTermDocs

Throws:

IOException

read

public final int read(int[] docs,
                      int[] freqs)
               throws IOException

Description copied from class: SegmentTermDocs

Optimized implementation.

Specified by:

read in interface TermDocs

Overrides:

read in class SegmentTermDocs

Throws:

IOException

skipProx

protected void skipProx(long proxPointer)
                 throws IOException

Called by super.skipTo().

Overrides:

skipProx in class SegmentTermDocs

Throws:

IOException
