Input Category Filter

• Description:

  This option defines the field to use as the input categories. This option specifies which field marks the syntactic categories of the input term.

  This option has effects on the following flow components: b, Ct, d, dc, e, i, ici, L, Lp, Ln, R, r, s, y.

  Note: The first field is 1. If this option is not present, all syntactic categories are applied for the inflection and derivation modules. If this option is present, this field should contain a long (integer) that is formed by OR'ing (or adding) the following integers:

  Value	Variant	Other Symbols
  1	adj	adjective ADJ
  2	adv	adverb ADV
  4	aux	auxiliary
  8	compl	complementizer
  16	conj	conjunction CON con
  32	det	determiner DET
  64	modal	.
  128	noun	NOM NPR
  256	prep	preposition PRE pre
  512	pron	pronoun
  1024	verb	VER ver

• Implementation Logic:
  1. Get the specified filed number of the input category filter.
  2. Get the specified categories from the input term by the specified field number.
  3. Assign the specified categories to the source category of the input LexItem.
  4. Do the filtering on flows: b, Ct, d, dc, e, i, ici, L, Lp, Ln, R, r, s, y.
