Parameters
candidates:List<ClassNode[]>

Doc from groovy.transform.stc.ClosureSignatureConflictResolver.resolve.

the list of signatures as determined after applying type hints and performing initial inference calculations

receiver:ClassNode

Doc from groovy.transform.stc.ClosureSignatureConflictResolver.resolve.

the receiver the method is being called on

arguments:Expression

Doc from groovy.transform.stc.ClosureSignatureConflictResolver.resolve.

the arguments for the closure

closure:ClosureExpression

Doc from groovy.transform.stc.ClosureSignatureConflictResolver.resolve.

the closure expression under analysis

methodNode:MethodNode

Doc from groovy.transform.stc.ClosureSignatureConflictResolver.resolve.

the method for which a groovy.lang.Closure parameter was annotated with ClosureParams

sourceUnit:SourceUnit

Doc from groovy.transform.stc.ClosureSignatureConflictResolver.resolve.

the source unit of the file being compiled

compilationUnit:CompilationUnit

Doc from groovy.transform.stc.ClosureSignatureConflictResolver.resolve.

the compilation unit of the file being compiled

options:String[]

Doc from groovy.transform.stc.ClosureSignatureConflictResolver.resolve.

the options, corresponding to the ClosureParams#options() found on the annotation

Returns:List<ClassNode[]>

Doc from groovy.transform.stc.ClosureSignatureConflictResolver.resolve.

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.
