AbstractMetaDataDefaults (OpenJPA Parent POM 3.2.0 API)

java.lang.Object
- org.apache.openjpa.meta.AbstractMetaDataDefaults

All Implemented Interfaces:

CallbackModes, MetaDataDefaults

Direct Known Subclasses:

PersistenceMetaDataDefaults
```
public abstract class AbstractMetaDataDefaults
extends Object
implements MetaDataDefaults
```
Abstract implementation provides a set of generic utilities for detecting persistence meta-data of Field/Member. Also provides bean-style properties such as access style or identity type to be used by default when such information is not derivable from available meta-data.

protected void populate(FieldMetaData fmd)
```
  - getFieldAccessNames
```
protected List<String> getFieldAccessNames(ClassMetaData meta)
```
    Return the list of fields in meta that use field access, or null if a list of fields is unobtainable. An empty list should be returned if the list of fields is obtainable, but there happens to be no field access in meta. This is used for error reporting purposes only, so need not be efficient. This implementation returns null.
  - getPropertyAccessNames
```
protected List<String> getPropertyAccessNames(ClassMetaData meta)
```
    Return the list of methods in meta that use property access, or null if a list of methods is unobtainable. An empty list should be returned if the list of methods is obtainable, but there happens to be no property access in meta. This is used for error reporting purposes only, so need not be efficient. This implementation returns null.
  - getFieldName
```
public static String getFieldName(Member member)
```
    Return the field name for the given member. This will only be invoked on members of the right type (field vs. method). Return null if the member cannot be managed. Default behavior: For fields, returns the field name. For getter methods, returns the minus "get" or "is" with the next letter lower-cased. For other methods, returns null.
  - isReservedFieldName
```
protected boolean isReservedFieldName(String name)
```
    Returns true if the given field name is reserved for unmanaged fields.
  - isDefaultPersistent
```

                                               boolean ignoreTransient)
```
    Return true if the given member is persistent by default. This will only be invoked on members of the right type (field vs. method). Returns false if member is static or final by default.
    
    Parameters:
    
    name - the field name from getFieldName(java.lang.reflect.Member)
  - getBackingMember
```
public Member getBackingMember(FieldMetaData fmd)
```
    Gets the backing member of the given field. If the field has not been assigned a backing member then get either the instance field or the getter method depending upon the access style of the defining class.
    Defining class is used instead of declaring class because this method may be invoked during parsing phase when declaring metadata may not be available.
    
    Specified by:
    
    getBackingMember in interface MetaDataDefaults
  - getUnimplementedExceptionType
```
public Class<?> getUnimplementedExceptionType()
```
    Description copied from interface: MetaDataDefaults
    
    Return a runtime exception class to throw for un-implemented managed interface methods.

protected static boolean isUserDefined(Class<?> cls)
```
    Helper method; returns true if the given class appears to be user-defined.
  - isNormalGetter
```
public static boolean isNormalGetter(Method method)
```
    Affirms if the given method matches the following signature public T getXXX() where T is any non-void type.
  - isBooleanGetter
```
public static boolean isBooleanGetter(Method method)
```
    Affirms if the given method matches the following signature public boolean isXXX() public Boolean isXXX()

    Affirms if the given method signature matches bean-style getter method signature.
    public T getXXX() where T is any non-void type.
