Constructor Detail

Cmp2Generator

public Cmp2Generator(String cmpImplClass,
             Class beanClass,
             String pkField,
             Class<?> primKeyClass,
             String[] cmpFields)

Constructor for a Cmp2Generator. This validates the initial EJB state information and prepares for the code generation process.

Parameters:

cmpImplClass - The name of the implementation class we're generating.

beanClass - The bean implementation class that is our starting point for code generation.

pkField - The name of the primary key field (optional if the primary key class is given).

primKeyClass - The optional primary key class for complex primary keys.

cmpFields - The list of fields that are managed using cmp.

Method Detail

addCmrField

public void addCmrField(CmrField cmrField)

Add a field to the list of fields defined as CMR fields. Note that if the field is also defined as a CMP field, it will be removed from the normal CMP list.

Parameters:

cmrField - The new CMR field definition pulled from the EJB metadata.

addSelectMethod

public void addSelectMethod(Method selectMethod)

Add a method to the list of ejbSelect methods that need to be processed.

Parameters:

selectMethod - The method that needs to be processed.

generate

public byte[] generate()

Perform the generation step for a CMP Entity Bean. This uses the accumulated meta data and the base bean class to generate a subclass with the automatically generated bits of OpenEJB infrastructure hooks.

Returns:

The class file byte array to be used for defining this class.
