Method Detail

load

public Object load(String batchId)

Specified by:

load in interface IBatchArtifactFactory

Parameters:

batchId - The value of a @ref attribute in a JSL element, e.g. 'batchlet'

Returns:

An object instance of the artifact.

obtainBeanManager

protected jakarta.enterprise.inject.spi.BeanManager obtainBeanManager()
                                                               throws NamingException

Throws:

NamingException

getBeanById

protected jakarta.enterprise.inject.spi.Bean<?> getBeanById(jakarta.enterprise.inject.spi.BeanManager bm,
                                                            String id)

Parameters:

id - Either the EL name of the bean, its id in batch.xml, or its fully qualified class name.

Returns:

the bean for the given artifact id.

getUniqueBeanByBeanName

protected jakarta.enterprise.inject.spi.Bean<?> getUniqueBeanByBeanName(jakarta.enterprise.inject.spi.BeanManager bm,
                                                                        String batchId)

Use the given BeanManager to lookup a unique CDI-registered bean with bean name equal to 'batchId', using EL matching rules.

Returns:

the bean with the given bean name, or 'null' if there is an ambiguous resolution

getUniqueBeanForBatchXMLEntry

protected jakarta.enterprise.inject.spi.Bean<?> getUniqueBeanForBatchXMLEntry(jakarta.enterprise.inject.spi.BeanManager bm,
                                                                              String batchId)

Use the given BeanManager to lookup a unique CDI-registered bean with bean class equal to the batch.xml entry mapped to be the batchId parameter

Returns:

the bean with the given className. It returns null if there are zero matches or if there is no umabiguous resolution (i.e. more than 1 match)
