question: free up any memory used by the deduplicator . concode_field_sep Map<BitSet,BitSet> canonicalBitSets concode_elem_sep Map<IntArray,IntArray> canonicalIntArrays concode_elem_sep String[] array concode_elem_sep Map<String,String> canonicalStrings concode_elem_sep long serialVersionUID concode_elem_sep Map<StringArray,StringArray> canonicalStringArrays concode_field_sep String deduplicateString concode_elem_sep BitSet deduplicateBitSet concode_elem_sep int hashCode concode_elem_sep int hashCode concode_elem_sep boolean equals concode_elem_sep boolean equals concode_elem_sep int[] deduplicateIntArray concode_elem_sep String[] deduplicateStringArray
target: void function ( ) { canonicalIntArrays . clear ( ) ; canonicalStrings . clear ( ) ; canonicalBitSets . clear ( ) ; canonicalStringArrays . clear ( ) ; }
