nextUID
public static java.lang.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 java.lang.String toTypeName(java.lang.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 java.lang.String[] toTypeNames(java.lang.Class[] types)
Converts a number of types (usually, arguments to a method or constructor) into their type names.
-
toWrapperType
public static java.lang.Class toWrapperType(java.lang.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 java.lang.reflect.Method getMethod(java.lang.Class declaringClass, java.lang.String name, java.lang.Class... parameterTypes)

.- Parameters:
declaringClass
- containing classname
- name of methodparameterTypes
- types of parameters- Returns:
- description for method
- Throws:
java.lang.RuntimeException
- if any error (such as method not found)
-
isPrimitive
public static boolean isPrimitive(java.lang.String typeName)
Determines if the provided type name is a primitive type.- Parameters:
