TO_STRING

public static final Method TO_STRING

Method Detail

nextUID

public static String nextUID()
Returns a string that can be used as part of a Java identifier and is unique for this JVM. Currently returns a hexadecimal string and initialized by System.nanoTime() (but both those details may change in the future).

Note that the returned value may start with a numeric digit, so it should be used as a suffix, not prefix of a Java identifier.

Returns:
unique id that can be used as part of a Java identifier

toTypeName

public static String toTypeName(Class type)
Converts a type (including array and primitive types) to their type name (the way they are represented in Java source files).


toTypeNames

public static String[] toTypeNames(Class[] types)
Converts a number of types (usually, arguments to a method or constructor) into their type names.


toWrapperType

public static Class toWrapperType(Class type)
Gets the wrapper type for a given type (if primitive)

Parameters:
type - type to look up
Returns:
the input type for non-primitive type, or corresponding wrapper type (Boolean.class for boolean.class, etc.)

getMethod

public static Method getMethod(Class declaringClass,
                               String name,
                               Class... parameterTypes)
Convenience for getting a method from a class.

Parameters:
declaringClass - containing class
name - name of method
parameterTypes - types of parameters
Returns:
the Method
Throws:
RuntimeException - if any error (such as method not found)

getMethodDescription

public static MethodDescription getMethodDescription(Class declaringClass,
                                                     String name,
                                                     Class... parameterTypes)
Uses getMethod(Class, String, Class...) and wraps the result as a MethodDescription.

Parameters:
declaringClass - containing class
name - name of method
parameterTypes - types of parameters
Returns:
description for method
Throws:
RuntimeException - if any error (such as method not found)

isPrimitive

public static boolean isPrimitive(String typeName)
Determines if the provided type name is a primitive type.

Parameters:
typeName - Java type name, such as "boolean" or "java.lang.String"
Returns:
true if primitive
