The BSgenome-based version of the SequenceTrack class

# S4 method for class 'SequenceBSgenomeTrack'
initialize(.Object, sequence = NULL, ...)

Arguments

.Object: The object skeleton passed on by new() during class instantiation, to be filled in by the initialize method.
sequence: A BSgenome object with the full genomic sequence, or NULL.
...: Additional arguments.

Value

An initialized object of class SequenceBSgenomeTrack.

Functions

initialize(SequenceBSgenomeTrack): Initialize the sequence and pointerCache slots before deferring to the SequenceTrack initializer for the remaining slots.

Slots

sequence: A BSgenome object (or NULL), realized on demand as individual chromosome sequences are accessed.
pointerCache: An environment holding pointers to the BSgenome sequences that have already been realized, to prevent garbage collection.
