Mutate

public static java.util.Vector<LexItem> Mutate(LexItem in,
                                               java.sql.Connection conn,
                                               RamTrie trie,
                                               int restrictFlag,
                                               int derivationType,
                                               int derivationNegation,
                                               boolean detailsFlag,
                                               boolean mutateFlag,
                                               boolean detailFlowFlag)

Performs the mutation of this flow component.

Parameters:

in - a LexItem as the input for this flow component

conn - LVG database connection

trie - LVG Ram trie

restrictFlag - a numberical flag to restrict out into LVG_ONLY LVG_OR_ALL, or ALL (defined in LvgFlowSpecificOption).

derivationType - a numberical flag to restrict derivation type D_TYPE_ZERO, D_TYPE_PREFIX, D_TYPE_SUFFIX, D_TYPE_ZERO_PREFIX, D_TYPE_ZERO_SUFFIX, D_TYPE_PREFIX_SUFFIX, D_TYPE_ALL (defined in LvgFlowSpecificOption);

derivationNegation - a numberical flag to restrict derivation negation D_NEGATION_OTHERWISE, D_NEGATION_NEGATIVE, D_NEGATION_BOTH

detailsFlag - a boolean flag for processing details information

mutateFlag - a boolean flag for processing mutate information

detailFlowFlag - a boolean flag for showing the flow history in details. For instance use ddd instead of R.

Returns:

the results from this flow component - a collection (Vector) of LexItems
