Method Detail

getName

public String getName(Method method)

Description copied from interface: FieldNameConverter

Generates a field name to correspond with the specified method. The algorithm used must not only be aware of the defined conventions (such as getters and setters) but also the annotations sometimes used to override the field name explicitly. AO will not test for these annotations separately from the field name converter.

Specified by:

getName in interface FieldNameConverter

Parameters:

method - The method for which a corresponding field name must be generated.

Returns:

A database field name which corresponds to the given method.

getPolyTypeName

public String getPolyTypeName(Method method)

Description copied from interface: FieldNameConverter

Generates a secondary field name which corresponds with the polymorphic type flag for the field corresponding to the specified method. If the method in question does not represent a polymorphic field, this method may return any value, or null. For most use-cases, the return value of this method will be identical to that of the FieldNameConverter.getName(Method) method with a conventional suffix (usually "Type" or "_type") to indicate that it is a polymorphic flag. Polymorphic fields are the only scenario in which two fields will correspond to a single method.

An example of a table with a polymorphic flagging field could be taken as follows (MySQL DDL):

CREATE TABLE comments (
     id INTEGER NOT NULL AUTO_INCREMENT,
     title VARCHAR(45),
     text TEXT,
     commentableID INTEGER,
     commentableType VARCHAR(255),
     PRIMARY KEY(id)
 );

Notice the absence of foreign key constraint on the commentableID field. This is because this table has a one-to-many mapping with potentially numerous tables which can be described as "commentable". Thus, commentableID and commentableType describe a polymorphic one-to-many relationship within the database.

Specified by:

getPolyTypeName in interface FieldNameConverter

Parameters:

method - The method for which a corresponding field name must be generated.

Returns:

A database field name which corresponds to the given method.

convertName

public String convertName(String name)
