Method Details

isAssignable

public static boolean isAssignable(Class<?> superType,
 Class<?> subType)

Check if the super-type may be assigned to the sub-type Considers primitive wrapper classes as assignable to the corresponding primitive types.

Parameters:

superType - the target type (left-hand side (LHS) type)

subType - the value type (right-hand side (RHS) type) that should be assigned to the target type

Returns:

true if rhsType is assignable to lhsType

getMethod

public static Method getMethod(Class<?> clazz,
 String methodName,
 Class<?>... paramTypes)

Determine whether the given class has a public method with the given signature, and return it if available (else return null).

In case of any signature specified, only returns the method if there is a unique candidate, i.e. a single public method with the specified name.

Essentially translates NoSuchMethodException to null.

Parameters:

clazz - the clazz to analyze

methodName - the name of the method

paramTypes - the parameter types of the method (can be null to indicate any signature)

Returns:

the method, or null if not found
