Class PickFirstResolver

  • public class PickFirstResolver
    extends ClosureSignatureConflictResolver
    Returns the first of several candidates found. This is useful if several types should be supported but only the first should be the default/inferred type. Other options in the list are obtained through explicitly typing the parameter(s).

        candidates - the list of signatures as determined after applying type hints and performing initial inference calculations
        receiver - the receiver the method is being called on
        arguments - the arguments for the closure
        closure - the closure expression under analysis
        methodNode - the method for which a Closure parameter was annotated with ClosureParams
        sourceUnit - the source unit of the file being compiled
        compilationUnit - the compilation unit of the file being compiled
        options - the options, corresponding to the ClosureParams.options() found on the annotation
        a non-null list of signatures, where a signature corresponds to an array of class nodes, each of them matching a parameter. A list with more than one element indicates that all ambiguities haven't yet been resolved.
