Method Detail

getComponentType

ReflectClass getComponentType()

getDeclaredFields

ReflectField[] getDeclaredFields()

getDeclaredField

ReflectField getDeclaredField(java.lang.String name)

getDelegate

ReflectClass getDelegate()

Returns the ReflectClass instance being delegated to. If there's no delegation it should return this.

Returns:

delegate or this

getMethod

ReflectMethod getMethod(java.lang.String methodName,
                      ReflectClass[] paramClasses)

getName

java.lang.String getName()

getSuperclass

ReflectClass getSuperclass()

isAbstract

boolean isAbstract()

isArray

boolean isArray()

isAssignableFrom

boolean isAssignableFrom(ReflectClass type)

isCollection

boolean isCollection()

isInstance

boolean isInstance(java.lang.Object obj)

isInterface

boolean isInterface()

isPrimitive

boolean isPrimitive()

newInstance

java.lang.Object newInstance()

reflector

Reflector reflector()

nullValue

java.lang.Object nullValue()

ensureCanBeInstantiated

boolean ensureCanBeInstantiated()

Calling this method may change the internal state of the class, even if a usable constructor has been found on earlier invocations.

Returns:

true, if instances of this class can be created, false otherwise

isImmutable

boolean isImmutable()

We need this for replication, to find out if a class needs to be traversed or if it simply can be copied across. For now we will simply return the classes that are isPrimitive() and Platform4.isSimple(Class) We can think about letting users add an Immutable annotation.
