    com.google.common.collect.RangeSet<Long>
    getCoveredRanges(com.google.common.collect.Range<Long> localRange)
    Return a set of contributions by this buffer for the given lookup range While this method does not expose which parts of the global range are covered, this method allows to check whether there are any gaps in the read
    Long
    getOffsetInRanges()
    The offset within the range set where this buffer starts; may be null if the offset cannot be represented in a single value such as in a union of two buffers which have different offsets
    com.google.common.collect.RangeSet<Long>
    getRanges()
    A set of ranges from which reading is valid.

  • Method Details

    • getRanges

      com.google.common.collect.RangeSet<Long> getRanges()
      A set of ranges from which reading is valid. The range set may be shared among several range buffers and may thus include ranges outside of the range formed by the buffer's offset and capacity

    • getOffsetInRanges

      Long getOffsetInRanges()
      The offset within the range set where this buffer starts; may be null if the offset cannot be represented in a single value such as in a union of two buffers which have different offsets

    • getBackingBuffer

      Buffer<A> getBackingBuffer()

    • getCoveredRanges

      com.google.common.collect.RangeSet<Long> getCoveredRanges(com.google.common.collect.Range<Long> localRange)
      Return a set of contributions by this buffer for the given lookup range While this method does not expose which parts of the global range are covered, this method allows to check whether there are any gaps in the read
