Predicates

calls	Holds if `callee` is potentially called from this callable. That is, `callee` is a potential run-time target of a call in the body of this callable.
canReturn	Holds if this callable can return expression `e`.
canYieldReturn	Holds if this callable can yield return the expression `e`.
getACall	Gets a `Call` that has this callable as a target.
getAParameter	Gets a parameter, if any.
getAStatementBody	DEPRECATED: Use `getStatementBody` instead.
getAnnotatedReturnType	Gets the annotated return type of this callable.
getBody	Gets the body of this callable, if any.
getCyclomaticComplexity	Gets the number of branching statements (`if`, `while`, `do`, `for`, `foreach` `switch`, `case`, `catch`) plus the number of branching expressions (`?`, `&&`, `\|\|`, `??`) plus one. Callables with a high cyclomatic complexity (> 10) are hard to test and maintain, given their large number of possible execution paths. They should be refactored.
getEnclosingCallable	Gets the enclosing callable of this callable, if any.
getEntryPoint	Gets the entry point in the control graph for this callable.
getExitPoint	Gets the exit point in the control graph for this callable.
getExpressionBody	Gets the expression body of this callable (if any), specified by `=>`.
getNumberOfLines	Gets the total number of lines in this callable.
getNumberOfLinesOfCode	Gets the number of lines containing code in this callable.
getNumberOfLinesOfComments	Gets the number of lines containing comments in this callable.
getReturnType	Gets the return type of this callable.
getStatementBody	Gets the statement body of this callable, if any.
getUnboundDeclaration	Gets the unbound version of this declaration, that is, the declaration where all type arguments have been removed. For example, in
hasBody	Holds if this callable has a body or an implementation.
hasExpressionBody	Holds if this callable has an expression body.
hasNonEmptyBody	Holds if this callable has a non-empty body. That is, either it has an expression body, or it has a non-empty statement body.
hasStatementBody	Holds if this callable has a statement body.
toStringWithTypes	Gets the full textual representation of this element, including type information.
