getDelegate

public ReflectClass getDelegate()

Description copied from interface: ReflectClass

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

Specified by:

getDelegate in interface ReflectClass

Returns:

delegate or this

getMethod

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

Specified by:

getMethod in interface ReflectClass

getName

public java.lang.String getName()

Specified by:

getName in interface ReflectClass

getSuperclass

public ReflectClass getSuperclass()

Specified by:

getSuperclass in interface ReflectClass

isAbstract

public boolean isAbstract()

Specified by:

isAbstract in interface ReflectClass

isArray

public boolean isArray()

Specified by:

isArray in interface ReflectClass

isAssignableFrom

public boolean isAssignableFrom(ReflectClass type)

Specified by:

isAssignableFrom in interface ReflectClass

isCollection

public boolean isCollection()

Specified by:

isCollection in interface ReflectClass

isInstance

public boolean isInstance(java.lang.Object obj)

Specified by:

isInstance in interface ReflectClass

isInterface

public boolean isInterface()

Specified by:

isInterface in interface ReflectClass

isPrimitive

public boolean isPrimitive()

Specified by:

isPrimitive in interface ReflectClass

newInstance

public java.lang.Object newInstance()

Specified by:

newInstance in interface ReflectClass

getJavaClass

public java.lang.Class<?> getJavaClass()

Specified by:

getJavaClass in interface JavaReflectClass

reflector

public Reflector reflector()

Specified by:

reflector in interface ReflectClass

getSerializableConstructor

public ReflectConstructor getSerializableConstructor()

Specified by:

getSerializableConstructor in interface ConstructorAwareReflectClass

nullValue

public java.lang.Object nullValue()

Specified by:

nullValue in interface ReflectClass

ensureCanBeInstantiated

public boolean ensureCanBeInstantiated()

Description copied from interface: ReflectClass

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

Specified by:

ensureCanBeInstantiated in interface ReflectClass

Returns:

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

isImmutable

public boolean isImmutable()

Description copied from interface: ReflectClass

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 ReflectClass.isPrimitive() and Platform4.isSimple(Class) We can think about letting users add an Immutable annotation.

Specified by:

isImmutable in interface ReflectClass
