matchPattern

Match pattern column to stringToMatch column and assigning tags based on a match.

Command line strings are input to a function, which tokenizes the command line arguments. Distinguishes between command line arguments and the values passed into the arguments. Then interprets metadata about the arguments and values.

The first step is properly parsing command line parameters the way the shell interpreter would parse them for interpretation before they are handed to the executable that will operate on those arguments.

Usage Details

LQL Command

matchPattern(table:TableReference, stringToMatch:String, patternTable:TableReference, pattern:String, tags:String, matchType:String)

Parameters:
table(TableReference)-The table to which the operate is applied
stringToMatch(String)-Column in a 'table' to match to pattern
patternTable(TableReference)-Table that contains patterns, tags and a matchType columns
pattern(String)-pattern column in a patternTable
tags(String)-tags column to assign after pattern matches
matchType(String)-match type of a pattern: '0'-> string match on each tokens in a string, '1'-> regex match on a tokens, '2'-> regex match on a whole string without tokenization.
