The matchCandidate method matches a record to the candidates that are in the match window. This method returns an array of keys and a corresponding array of match patterns for each candidate that matches.
This method does not return match suspects. To return match suspects as well as matches, use the matchCandidateWithSuspects method described in matchCandidateWithSuspects().
This method has two signatures. Choose one depending on whether or not you want to explicitly identify the match level.

|
handle |
int |
In |
–– |
Handle to a Director matcher server instance. |
|
trillName |
string[ ] |
In |
n* |
Array of strings that contains the field names of the record to match. These field names correspond to the field names in the DDL files. |
|
inputData |
string[ ] |
In |
n* |
Array of strings that contains data to match. |
|
key |
string[ ] |
Out |
n* |
Array of strings that contains the keys of the candidates that matched the input record. This array must be pre-allocated by the caller with the number of elements equal to the number of records in the match window. |
|
matchPattern |
string[ ] |
Out |
n* |
Array of strings that contains the match patterns that correspond to the candidate keys returned in key. This array must be pre-allocated by the caller with the number of elements equal to the number of records in the match window. |
|
matchLevel |
int |
In |
-- |
Match level to be performed: 1 or 2. If not specified, it defaults to Level 1. |
|
retCode |
int[ ] |
Out |
4 |
Error code that indicates the status of the method call |
n* indicates the maximum length. The total length depends on the number of elements allocated and the plaform on which the program is run.

Example
TrilTGenClient testClient = new TrilTGenClient();
int[] retCode = new int[1]; // Return code and handle
int handle = 0;
char systemID; // System and Server ID for attach()
String serverName;
String[] matchFields = {"FirstName", "LastName", "MiddleName"};
String[] inputData = new String[3];
String keyValue;
String[] outPats = new String[12];
String[] outKeys = new String[12];
systemID = 'G';
serverName = "RMatcher";
handle = testClient.openMatcherEx(systemID, serverName, retCode);
testClient.clearWindow(handle, retCode); // Error handling omitted
inputData[0] = "JOHN";
inputData[1] = "SMITH";
inputData[2] = "D";
keyValue = "1ST JOHN";
testClient.addToMatchWindow(handle, matchFields, inputData, keyValue,
retCode);
inputData[0] = "JOHNATHAN";
inputData[1] = "SMITH";
inputData[2] = "DAVID";
keyValue = "2ND JOHN";
testClient.addToMatchWindow(handle, matchFields, inputData, keyValue,
retCode);
inputData[0] = "J";
inputData[1] = "SMITH";
inputData[2] = "D";
keyValue = "3RD JOHN";
testClient.addToMatchWindow(handle, matchFields, inputData, keyValue,

inputData[0] = "JOHN";
inputData[1] = "SMITH";
inputData[2] = "";
// Match this record
testClient.matchCandidate(handle, matchFields, inputData, outKeys, outPats,
