Method Detail- 
convertClosureToSourcepublic static String convertClosureToSource(ReaderSource readerSource, ClosureExpression expression) throws Exception Converts a ClosureExpression into the String source.- Parameters:
- readerSource- a source
- expression- a closure. Can't be null
- Returns:
- the source the closure was created from
- Throws:
- IllegalArgumentException- when expression is null
- Exception- when closure can't be read from source

- true if it has exactly one argument and the type is char or Character
 
 - 
hasSingleStringArgpublic static boolean hasSingleStringArg(Closure c) Does the Closure have a single String argument.- Parameters:
- c- a Closure
- Returns:
- true if it has exactly one argument and the type is String
 
 - 
hasImplicitParameterpublic static boolean hasImplicitParameter(ClosureExpression ce) - Returns:
- true if the ClosureExpression has an implicit 'it' parameter
 
 - 
getParametersSafepublic static Parameter[] getParametersSafe(ClosureExpression ce) - Returns:
- the parameters for the ClosureExpression
 
 -
