Interface OutputFactory

All Known Implementing Classes:

AggregateTableOutputFactory, RuleBasedAggregateTableOutputFactory

public interface OutputFactory

Factory that allows the creation of outputs, such as AggregateTableOutput, MaterialzedViewOutput, and/or AJIOutput objects.

It should register with the OutputService.

Method Summary

Methods

Modifier and Type	Method and Description
boolean	canCreateOutput(Schema schema) returns true if the factory can create an output.
Output	createOutput(Schema schema, Aggregate aggregate) create an output object, populating it with default values.
List<Output>	createOutputs(Schema schema, List<Aggregate> aggregates) create a list of output objects, populating them with default values.
Class<? extends Output>	getOutputClass() this is the output implementation class this factory generates.

Method Detail

canCreateOutput

boolean canCreateOutput(Schema schema)

returns true if the factory can create an output. in the future, this call may include parameters for overriding default behaviors.

Parameters:

schema - the current schema object

Returns:

true if this factory applies

getOutputClass

Class<? extends Output> getOutputClass()

this is the output implementation class this factory generates. this call is used by the Output Service to resolve the correct list of supported generators

Returns:

output class type

createOutput

Output createOutput(Schema schema,
                  Aggregate aggregate)

create an output object, populating it with default values.

Parameters:

schema - schema object

aggregate - aggregate object

Returns:

new output object

createOutputs

List<Output> createOutputs(Schema schema,
                         List<Aggregate> aggregates)

create a list of output objects, populating them with default values.

Parameters:

schema - schema object

aggregates - aggregate list

Returns:

new output object list
