Method Details

isMainMethod

public static boolean isMainMethod(MethodTree m)

parentMethodInvocationOfArgumentAtPos

@Nullable
public static MethodInvocationTree parentMethodInvocationOfArgumentAtPos(@Nullable
 ExpressionTree argumentCandidate,
 int expectedArgumentPosition)

Returns:

null when: - argumentCandidate is null - the parent is not a method invocation (ignoring parent parentheses) - argumentCandidate is not at the expected argument position Otherwise, returns the parent method invocation.
