Reduce casting clutter....
return (CollectionMapping)this.getMapping();
|
| protected oracle.toplink.essentials.mappings.ForeignReferenceMapping | getForeignReferenceMapping()INTERNAL:
Reduce casting clutter....

return mapping;
|
| protected oracle.toplink.essentials.mappings.ObjectReferenceMapping | getOneToOneMapping()INTERNAL:

|
| public abstract java.lang.Object | getOriginalIndirectionObject(java.lang.Object unitOfWorkIndirectionObject, oracle.toplink.essentials.internal.sessions.AbstractSession session)INTERNAL:
Return the original indirection object for a unit of work indirection object.
|
| public abstract java.lang.Object | getRealAttributeValueFromObject(java.lang.Object object, java.lang.Object attribute)INTERNAL:
Return the "real" attribute value, as opposed to any wrapper.
This will trigger the wrapper to instantiate the value.
|
| public static java.lang.Object | getValueFromProxy(java.lang.Object value)INTERNAL:
Given a proxy object, trigger the indirection and return the actual object represented by the proxy.
For non-proxy indirection, this method will simply return the object.
return value;
|
| public void | initialize()INTERNAL:
Initialize the indirection policy (Do nothing by default)
|
| public void | iterateOnAttributeValue(oracle.toplink.essentials.internal.descriptors.DescriptorIterator iterator, java.lang.Object attributeValue)INTERNAL:
Iterate over the specified attribute value,
heeding the settings in the iterator.
if (attributeValue != null) {
this.getMapping().iterateOnRealAttributeValue(iterator, attributeValue);
}
|
| public abstract java.lang.Object | nullValueFromRow()INTERNAL:
Return the null value of the appropriate attribute. That is, the
field from the database is NULL, return what should be
placed in the object's attribute as a result.
|
| public abstract boolean | objectIsInstantiated(java.lang.Object object)INTERNAL:
Return whether the specified object is instantiated.
|
| public void | setMapping(oracle.toplink.essentials.mappings.DatabaseMapping mapping)INTERNAL:
set the database mapping that uses the indirection policy.
this.mapping = mapping;
|
| public void | setRealAttributeValueInObject(java.lang.Object target, java.lang.Object attributeValue)INTERNAL:
Set the value of the appropriate attribute of target to attributeValue.
In this case, simply place the value inside the target.
this.getMapping().setAttributeValueInObject(target, attributeValue);
|
| public boolean | usesIndirection()INTERNAL:
Return whether the indirection policy actually uses indirection.
The default is true.
return true;
|
| public boolean | usesTransparentIndirection()INTERNAL:
Return whether the indirection policy uses transparent indirection.
The default is false.
return false;
|
| public java.lang.Object | validateAttributeOfInstantiatedObject(java.lang.Object attributeValue)INTERNAL:
Verify that the value of the attribute within an instantiated object
is of the appropriate type for the indirection policy.
If it is incorrect, throw an exception.
If the value is null return a new indirection object to be used for the attribute.
return attributeValue;
|
| public void | validateContainerPolicy(oracle.toplink.essentials.exceptions.IntegrityChecker checker)INTERNAL:
Verify that the container policy is compatible with the
indirection policy. If it is incorrect, add an exception to the
integrity checker.
// by default, do nothing
|
| public void | validateDeclaredAttributeType(java.lang.Class attributeType, oracle.toplink.essentials.exceptions.IntegrityChecker checker)INTERNAL:
Verify that attributeType is correct for the
indirection policy. If it is incorrect, add an exception to the
integrity checker.
// by default, do nothing
|
| public void | validateDeclaredAttributeTypeForCollection(java.lang.Class attributeType, oracle.toplink.essentials.exceptions.IntegrityChecker checker)INTERNAL:
Verify that attributeType is an appropriate collection type for the
indirection policy. If it is incorrect, add an exception to the integrity checker.
// by default, do nothing
|
| public void | validateGetMethodReturnType(java.lang.Class returnType, oracle.toplink.essentials.exceptions.IntegrityChecker checker)INTERNAL:
Verify that getter returnType is correct for the
indirection policy. If it is incorrect, add an exception
to the integrity checker.
// by default, do nothing
|
| public void | validateGetMethodReturnTypeForCollection(java.lang.Class returnType, oracle.toplink.essentials.exceptions.IntegrityChecker checker)INTERNAL:
Verify that getter returnType is an appropriate collection type for the
indirection policy. If it is incorrect, add an exception to the integrity checker.
// by default, do nothing
|
| public void | validateSetMethodParameterType(java.lang.Class parameterType, oracle.toplink.essentials.exceptions.IntegrityChecker checker)INTERNAL:
Verify that setter parameterType is correct for the
indirection policy. If it is incorrect, add an exception
to the integrity checker.
// by default, do nothing
|
| public void | validateSetMethodParameterTypeForCollection(java.lang.Class parameterType, oracle.toplink.essentials.exceptions.IntegrityChecker checker)INTERNAL:
Verify that setter parameterType is an appropriate collection type for the
indirection policy. If it is incorrect, add an exception to the integrity checker.
// by default, do nothing
|
| public abstract java.lang.Object | valueFromQuery(oracle.toplink.essentials.queryframework.ReadQuery query, oracle.toplink.essentials.internal.sessions.AbstractRecord row, oracle.toplink.essentials.internal.sessions.AbstractSession session)INTERNAL:
Return the value to be stored in the object's attribute.
This value is determined by the query.
|
| public abstract java.lang.Object | valueFromRow(java.lang.Object object)INTERNAL:
Return the value to be stored in the object's attribute.
This value is determined by the row.
