searchToken

public java.lang.String searchToken(java.lang.String[] tokenList)

Search the remaining tokens in the query for any of the tokens in the array received as a parameter. If the token is found then the queue is advanced to the position of the token found.

Parameters:

tokenList - the token list

Returns:

the string

searchTwoTokens

public java.lang.String[] searchTwoTokens(java.lang.String[] firstToken,

Search for any of the tokens in the list of firstTokens. If one is found then the next token in the tokens list is compared against the list of nextTokens. if one is found then the queue is advanced to the end of the second token and the two consecutive tokens are returned. If it is not found then the queue is not advanced.

nextToken - the next token

Returns:

the string[]
