T
- the annotated class type.public abstract class AbstractBeanListProcessor<T,C extends Context> extends AbstractBeanProcessor<T,C>
Processor
implementation for storing all java objects generated form the parsed input into a list.
A typical use case of this class will be:
parserSettings.setRowProcessor(new BeanListProcessor(MyObject.class)); parser.parse(reader); // will invoke the {@link AbstractBeanListProcessor#beanProcessed(Object, C)} method for each generated object. List<T> beans = rowProcessor.getBeans();

AbstractBeanListProcessor(java.lang.Class<T> beanType)
Creates a processor that stores java beans of a given type into a list
|
Modifier and Type | Method and Description |
---|---|
void |
beanProcessed(T bean,
C context)
Stores the generated java bean produced with a parsed record into a list.
|
java.util.List<T> |
getBeans()
Returns the list of generated java beans at the end of the parsing process.
|
java.lang.String[] |
getHeaders()
Returns the record headers.
|
void |
processEnded(C context)
This method will by invoked by the parser once, after the parsing process stopped and all resources were closed.
|
void |
processStarted(C context)
This method will by invoked by the parser once, when it is ready to start processing the input.
