public abstract class AbstractMultiBeanRowProcessor<C extends Context> extends AbstractMultiBeanProcessor<C>
Processor
implementation for converting rows extracted from any implementation of AbstractParser
into java objects.
The class types passed to the constructor of this class must contain the annotations provided in com.univocity.parsers.annotations
.
For each row processed, one or more java bean instances of any given class will be created with their fields populated.
Once all beans are populated from an individual input record, they will be sent to through the rowProcessed(Map, Context)
method,
where the user can access all beans parsed for that row.

Creates a processor for java beans of multiple types

Modifier and Type | Method and Description |

void |
beanProcessed(java.lang.Class<?> beanType,
java.lang.Object beanInstance,
C context)
Invoked by the processor after all values of a valid record have been processed and converted into a java object.
|
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.

protected abstract void |
rowProcessed(java.util.Map<java.lang.Class<?>,java.lang.Object> row,
C context)
Invoked by the processor after all beans of a valid record have been processed.

It will always be called by the parser: in case of errors, if the end of the input us reached, or if the user stopped the process manually using Context.stop()
