Class ToInflection

java.lang.Object

gov.nih.nlm.nls.lvg.Flows.Transformation

gov.nih.nlm.nls.lvg.Flows.ToInflection

All Implemented Interfaces:

java.lang.Cloneable

public class ToInflection
extends Transformation
implements java.lang.Cloneable

This class provides features of generating inflectional variants. This class handles cases in the following two ways:

• case insensitive search while making the SQL query
• the results preserve original case

This feature is handled by adding another columns (lowercased) for inflection terms in the Inflection table of Lvg DB.

Method Detail

Mutate

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

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 for inflection

restrictFlag - a numerical flag to filter the output. It's values are defined in LvgFlowSpecificOption as: LVG_ONLY, LVG_OR_ALL, ALL.

detailsFlag - a boolean flag for processing details information

mutateFlag - a boolean flag for processing mutate information

Returns:

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

Parameters:

args - arguments

InflectWords

static java.util.Vector<LexItem> InflectWords(LexItem in,
                                              java.sql.Connection conn,
                                              RamTrie trie,

                                              int flowName)

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 numerical flag to filter the output. It's values are defined in LvgFlowSpecificOption as:
LVG_ONLY, LVG_OR_ALL, ALL.

infoStr - the header of detail information, usually is the full name of the current flow

detailsFlag - a boolean flag for processing details information

mutateFlag - a boolean flag for processing mutate information

flowName - the abbreviation of this flow component for history

Returns:

A Vector of LexItem - results from this flow component
