Method Details

isMainMethod

public static boolean isMainMethod(MethodTree m,
 JavaVersion javaVersion)

compareMainMethodPriority

public static int compareMainMethodPriority(MethodTree compared,
 MethodTree reference)

Compares the priority of two main methods. In Java 25 and above, a main method with a String[] parameter has higher priority than a main method without parameters. In earlier versions of Java, only a main method with a String[] parameter is considered valid.

Parameters:

compared - : first main method to compare

reference - : second main method to compare

Returns:

1 if m1 has higher priority, -1 if m2 has higher priority, 0 if both have the same priority

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.
