Method Detail

getAttributeValueFromObject

public Object getAttributeValueFromObject(Object anObject)
                                   throws DescriptorException

Gets the value of an instance variable in the object.

Specified by:

getAttributeValueFromObject in interface CoreAttributeAccessor

Overrides:

getAttributeValueFromObject in class MethodAttributeAccessor

Throws:

DescriptorException

getGetMethodReturnType

public Class<?> getGetMethodReturnType()

Return the method return type. In a name access usage the return type currently must be Object.class.

Overrides:

getGetMethodReturnType in class MethodAttributeAccessor

getSetMethodParameterType

public Class<?> getSetMethodParameterType()

Return the set method parameter type. In a name access usage there must be an extra String parameter along with the Object.class type so we must check and return a different index from the parameter types.

Overrides:

getSetMethodParameterType in class MethodAttributeAccessor

getSetMethodParameterTypes

protected Class<?>[] getSetMethodParameterTypes()

Return the set method parameter types.

Overrides:

getSetMethodParameterTypes in class MethodAttributeAccessor

initializeAttributes

public void initializeAttributes(Class<?> theJavaClass)
                          throws DescriptorException

Set get and set method after creating these methods by using get and set method names

Specified by:

initializeAttributes in interface CoreAttributeAccessor

Overrides:

initializeAttributes in class MethodAttributeAccessor

Throws:

DescriptorException

isVirtualAttributeAccessor

public boolean isVirtualAttributeAccessor()

Overrides:

isVirtualAttributeAccessor in class AttributeAccessor

setAttributeValueInObject

public void setAttributeValueInObject(Object domainObject,
                                      Object attributeValue)
                               throws DescriptorException

Sets the value of the instance variable in the object to the value.

Specified by:

setAttributeValueInObject in interface CoreAttributeAccessor

Overrides:

setAttributeValueInObject in class MethodAttributeAccessor

Throws:

DescriptorException

setValueType

public void setValueType(Class<?> value)

Override the class of the values being stored.
