Class ClosureSignatureConflictResolver

  • Direct Known Subclasses:

    public class ClosureSignatureConflictResolver
    extends Object
    If multiple candidate signatures are found after applying type hints, a conflict resolver can attempt to resolve the ambiguity.

        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.
