Constructor Detail

• BitsRowSubset

  public BitsRowSubset(java.lang.String name,
                       java.util.BitSet bits,
                       boolean invert)

  Constructs a new row subset with a given BitSet, name and sense. The invert argument indicates whether the sense of the bit set is to be reversed prior to interpretation.

  Parameters:

  name - subset name

  bits - flag vector

  invert - whether to invert the bits from the BitSet

• BitsRowSubset

  public BitsRowSubset(java.lang.String name,
                       java.util.BitSet bits)

  Constructs a new row subset with a given BitSet and name. Same as BitsRowSubset(name,bits,false)

  Parameters:

  name - subset name

  bits - flag vector

Method Detail

• getBitSet

  public java.util.BitSet getBitSet()

  Returns the BitSet object used to store the inclusion status flags.

  Returns:

  flag vector

• getInvert

  public boolean getInvert()

  Returns the inversion sense of the inclusion flags represented by this subset relative to the bit set.

  Returns:

  true iff bitset bits are inverted to give inclusion flag

• isIncluded

  public boolean isIncluded(long lrow)

  Description copied from class: RowSubset
  Indicates whether a given row is in the subset or not.

  Specified by:

  isIncluded in class RowSubset

  Parameters:

  lrow - the index of the row in question

  Returns:

  true iff row lrow is to be included
