Class AttributeSetResultsDatabaseFactory

java.lang.Object

modelarium.attributes.results.databases.AttributeSetResultsDatabaseFactory

public final class AttributeSetResultsDatabaseFactory
extends Object

Factory class for creating instances of AttributeSetResultsDatabase.

Supports dynamic switching between in-memory and disk-based result storage via static configuration methods. This allows the simulation to use different result backends without changing core logic.

Method Summary

Modifier and Type	Method	Description
static void	clearCustomFactory()	Clears any custom factory that was previously set, reverting to default behaviour.
static AttributeSetResultsDatabase	createDatabase()	Creates a new instance of the configured results database.
static void	setCustomFactory(Supplier<AttributeSetResultsDatabase> factory)	Sets a custom factory to be used instead of the default class-based instantiation.
static <T extends AttributeSetResultsDatabase> void	setDatabaseClass(Class<T> databaseClass)	Manually sets the class used for creating result databases.
static void	setDatabaseToDiskBased()	Sets the results database to use a disk-based SQLite backend.
static void	setDatabaseToMemoryBased()	Sets the results database to use an in-memory backend.

Method Details

setDatabaseClass

public static <T extends AttributeSetResultsDatabase>
void setDatabaseClass(Class<T> databaseClass)

Manually sets the class used for creating result databases.

Type Parameters:

T - the database type

Parameters:

databaseClass - a class that extends AttributeSetResultsDatabase and has a no-argument constructor

setCustomFactory

public static void setCustomFactory(Supplier<AttributeSetResultsDatabase> factory)

Sets a custom factory to be used instead of the default class-based instantiation. This is useful for testing.

Parameters:

factory - the custom supplier of AttributeSetResultsDatabase instances

clearCustomFactory

public static void clearCustomFactory()

Clears any custom factory that was previously set, reverting to default behaviour.

setDatabaseToMemoryBased

public static void setDatabaseToMemoryBased()

Sets the results database to use an in-memory backend. Useful for lightweight or test simulations.

setDatabaseToDiskBased

public static void setDatabaseToDiskBased()

Sets the results database to use a disk-based SQLite backend. Useful for full-scale runs or persistent storage.

createDatabase

public static AttributeSetResultsDatabase createDatabase()

Creates a new instance of the configured results database.

If no database class has been configured, the default is a disk-based database. A unique database path is generated automatically.

Returns:

a new AttributeSetResultsDatabase instance, or null on error
