public class FindFunctionExtension
extends io.siddhi.core.executor.function.FunctionExecutor<io.siddhi.extension.execution.regex.FindFunctionExtension.ExtensionState>

Class representing the Regex Find implementation. find(regex, input.sequence) find(regex, input.sequence, starting.index) These methods attempts to find the next sub-sequence of the 'inputSequence' that matches the 'regex' pattern. regex - regular expression. eg: "\d\d(.*)WSO2" inputSequence - input sequence to be matched with the regular expression eg: "21 products are produced by WSO2 currently startingIndex - starting index of the input sequence to start matching the given regex pattern eg: 1, 2 Accept Type(s) for find(regex, input.sequence); regex : STRING input.sequence : STRING Accept Type(s) for find(regex, input.sequence, starting.index); regex : STRING input.sequence : STRING starting.index : INT Return Type(s): BOOLEAN
