All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class WeavedObjectBasicIndirectionPolicy
extends BasicIndirectionPolicy

A WeavedObjectBasicIndirectionPolicy is used by OneToOne mappings that are LAZY through weaving and which use Property(method) access. It extends BasicIndirection by providing the capability of calling the set method that was initially mapped in addition to the set method for the weaved valueholder in order to coordinate the value of the underlying property with the value stored in the valueholder

Constructor Detail

WeavedObjectBasicIndirectionPolicy

public WeavedObjectBasicIndirectionPolicy(java.lang.String getMethodName,
                                          java.lang.String setMethodName,
                                          java.lang.String actualTypeClassName,
                                          boolean hasUsedMethodAccess)

Method Detail

getActualTypeClassName

public java.lang.String getActualTypeClassName()

getRealAttributeValueFromObject

public java.lang.Object getRealAttributeValueFromObject(java.lang.Object object,
                                                        java.lang.Object attribute)

Return the "real" attribute value, as opposed to any wrapper. This will trigger the wrapper to instantiate the value. In a weaved policy, this will also call the initial setter method to coordinate the values of the valueholder with the underlying data.

Overrides:

getRealAttributeValueFromObject in class BasicIndirectionPolicy

updateValueInObject

public void updateValueInObject(java.lang.Object object,
                                java.lang.Object value,
                                java.lang.Object attributeValue)

Coordinate the valueholder for this mapping with the underlying property by calling the initial setter method.

setRealAttributeValueInObject

public void setRealAttributeValueInObject(java.lang.Object target,
                                          java.lang.Object attributeValue)

Set the value of the appropriate attribute of target to attributeValue. In this case, place the value inside the target's ValueHolder. Change tracking will be turned off when this method is called

Overrides:

setRealAttributeValueInObject in class BasicIndirectionPolicy

setRealAttributeValueInObject

public void setRealAttributeValueInObject(java.lang.Object target,
                                          java.lang.Object attributeValue,
                                          boolean trackChanges)

Set the value of the appropriate attribute of target to attributeValue. In this case, place the value inside the target's ValueHolder. if trackChanges is true, set the value in the object as if the user was setting it. Allow change tracking to pick up the change.

Overrides:

setRealAttributeValueInObject in class IndirectionPolicy

getGetMethodName

public java.lang.String getGetMethodName()

getSetMethodName

public java.lang.String getSetMethodName()

hasUsedMethodAccess

public boolean hasUsedMethodAccess()

isWeavedObjectBasicIndirectionPolicy

public boolean isWeavedObjectBasicIndirectionPolicy()
