NAME

Bio::JBrowse::Store::NCList::LazyNCList

new

Title   : new
Usage   : Bio::JBrowse::Store::NCList::LazyNCList->new(
              $attrs, $lazyClass, $makeLazy,
              $measure, $output, $sizeThresh
Function: create a LazyNCList
Returns : an LazyNCList object
Args    : $attrs is a reference to an ArrayRepr instance
          $lazyClass is the class number to be used for 'lazy'
             NCLists, which are references to sub-lists,
          $makeLazy is a reference to a sub taking the arguments
             (start, end, ID), which returns a "lazy feature" with the
             given attributes
          $loadChunk is a subroutine that takes a chunk ID number and returns the contents of that chunk (
          $measure is a reference to a sub that takes a feature to be
             output, and returns the number of bytes that feature will
             take up in the output
          $output is a reference to a sub that, given a chunk ID and some data,
             will output that data under that chunk ID
          $sizeThresh is the target chunk size

addSorted

Title   : addSorted
Usage   : $ncl->addSorted($feat)
Function: Adds a single feature to the set of features in this LazyNCList;
          features passed to this method are accumulated into "chunks";
          once a chunk grows to sizeThresh, the chunk is output.
          The features given to addSorted must be sorted by the NCList sort.
Returns : nothing meaningful
Args    : $feat is the feature to be added;

finish

Title   : finish
Usage   : $ncl->finish()
Function: Once all features have been added (through addSorted),
          call "finish" to flush all of the partial chunks.
          After calling finish, you can access the "topLevelList" property.
Returns : nothing

overlapCallback( $from, $to, \&func )

Calls the given function once for each of the intervals that overlap the given interval if <$from <= $to>, iterates left-to-right, otherwise iterates right-to-left.
