Class PersistentFieldIntrospectorImpl
java.lang.Object
org.apache.ojb.broker.metadata.fieldaccess.PersistentFieldBase
org.apache.ojb.broker.metadata.fieldaccess.PersistentFieldIntrospectorImpl
- All Implemented Interfaces:
- PersistentField, java.io.Serializable
- Direct Known Subclasses:
- PersistentFieldIntrospectorImplNew
- public class PersistentFieldIntrospectorImpl
- extends PersistentFieldBase
A PersistentField
implementation using
JavaBeans compliant calls only to access persistent attributes.
No Reflection is needed. But for each attribute xxx there must be
public getXxx() and setXxx() methods. In metadata the field name must be
the bean compliant 'xxx'.

throws MetadataException
- Description copied from interface:
PersistentField
- Sets the field represented by this PersistentField object on the specified object argument to the specified new value.
The new value is automatically unwrapped if the underlying field has a primitive type.
This implementation invokes set() on its underlying Field object if the argument is not null.
OBS IllegalArgumentExceptions are wrapped as PersistenceBrokerExceptions.
- Parameters:
target
- The target object (no proxy objects allowed).value
- The value to set.
- Throws:
MetadataException
- if there is an error setting this field value on obj- See Also:

get
public java.lang.Object get(java.lang.Object target)
throws MetadataException
- Description copied from interface:
PersistentField
- Returns the value of the field represented by this PersistentField, on the specified object.
This implementation invokes get() on its underlying Field object.
- Parameters:
target
- - The object instance (proxy objects are not allowed here) which we are
trying to get the field value from.
- Throws:
MetadataException
- if there is an error getting this field value from obj- See Also:
Field
makeAccessible
public boolean makeAccessible()
- This implementation returns always 'false'.
usesAccessorsAndMutators
public boolean usesAccessorsAndMutators()
- Always returns 'false'.
