Module org.eclipse.persistence.core

Package org.eclipse.persistence.internal.descriptors

Class MethodAttributeAccessor

java.lang.Object

org.eclipse.persistence.mappings.AttributeAccessor

org.eclipse.persistence.internal.descriptors.MethodAttributeAccessor

All Implemented Interfaces:

Serializable, Cloneable, CoreAttributeAccessor

Direct Known Subclasses:

VirtualAttributeAccessor

public class MethodAttributeAccessor
extends AttributeAccessor

Purpose: A wrapper class for handling cases when the domain object attributes are to be accessed thru the accessor methods. This could happen if the variables are not defined public in the domain object.

Since:

TOPLink/Java 1.0

Method Detail

getAttributeClass

public Class<?> getAttributeClass()

Return the return type of the method accessor.

Specified by:

getAttributeClass in interface CoreAttributeAccessor

Overrides:

getAttributeClass in class AttributeAccessor

getAttributeValueFromObject

public Object getAttributeValueFromObject(Object anObject)
                                   throws DescriptorException

Gets the value of an instance variable in the object.

Specified by:

getAttributeValueFromObject in interface CoreAttributeAccessor

Specified by:

getAttributeValueFromObject in class AttributeAccessor

Throws:

DescriptorException

getAttributeValueFromObject

protected Object getAttributeValueFromObject(Object anObject,
                                             Object[] parameters)
                                      throws DescriptorException

getGetMethod

public Method getGetMethod()

Return the accessor method for the attribute accessor. 266912: For Metamodel API - change visibility from protected

getGetMethodName

public String getGetMethodName()

Return the name of the accessor method for the attribute accessor.

getGetMethodReturnType

public Class<?> getGetMethodReturnType()
                                throws DescriptorException

INTERNAL: Return the GetMethod return type for this MethodAttributeAccessor. A special check is made to determine if a missing method is a result of failed weaving.

Throws:

DescriptorException

getSetMethod

protected Method getSetMethod()

Return the set method for the attribute accessor.

getSetMethodName

public String getSetMethodName()

Return the name of the set method for the attribute accessor.

getSetMethodParameterType

public Class<?> getSetMethodParameterType()

getSetMethodParameterType

protected Class<?> getSetMethodParameterType(int index)

getSetMethodParameterTypes

protected Class<?>[] getSetMethodParameterTypes()

initializeAttributes

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