callMethodIfPresent

@CheckForNull
public static Object callMethodIfPresent(@Nullable
 Object pObject,
 @Nonnull
 String pMethodName,
 @Nullable
 Object... pParameters)

Call the given method on the given object if it exists and return the result.

Parameters:

pObject - an object

pMethodName - the name of a parameterless method

pParameters - the parameters to pass to the called method, or null / left out for none

Returns:

the method's return value. A result of null may mean that the method did not exist, or its return value was null, or its return type was void.

callScheduledNodesVistor

public static void callScheduledNodesVistor(@Nullable
 Object pObject,
 @Nonnull
 BiConsumer<List<org.gradle.execution.plan.Node>,Set<org.gradle.execution.plan.Node>> pVisitor)

loadClassIfPossible

@CheckForNull
public static Class<?> loadClassIfPossible(@Nonnull
 String pFqcn)

isInstanceOf

public static boolean isInstanceOf(@Nonnull
 String pSuperFqcn,
 @Nullable
 Object pObject)

Tries to load the class determined by pSuperFqcn, and on success, determines if the given object is an instance of it.

Parameters:

pSuperFqcn - fully qualified class name of the potential superclass

pObject - any object

Returns:

true if pSuperFqcn could be loaded and pObject is an instance of it; false if either is not the case
