forEachFact

void forEachFact(BiConsumer<FactHandle,Object> consumer)

forEachFact

default <T> void forEachFact(Class<T> type,
Consumer<T> consumer)

A memory inspection method that accepts fact type as an argument.

Type Parameters:

T - expected java type for the provided type name

Parameters:

type - expected fact type

consumer - consumer for the facts

Throws:

ClassCastException - if a working memory object can not be cast to the specified type

IllegalArgumentException - if no such type exists

See Also:

TypeResolver

forEachFact

<T> void forEachFact(String type,
Consumer<T> consumer)

A memory inspection method that accepts fact type as an argument. Type name can be either a class name or a name of explicitly declared type. In the latter case, the generic type parameter T must match the declared type's Java type (see Type.getJavaType())

Type Parameters:

T - expected java type for the provided type name

Parameters:

type - type name

consumer - consumer for the facts

Throws:

ClassCastException - if a working memory object can not be cast to the specified type

IllegalArgumentException - if no such type exists

See Also:

TypeResolver

forEachFact

default <T> void forEachFact(Class<T> type,
Predicate<T> filter,
Consumer<T> consumer)

A filtering version of the forEachFact(Class, Consumer) method.

Type Parameters:

T - expected java type for the provided type name

Parameters:

type - expected fact type

consumer - consumer for the facts

filter - filtering predicate

See Also:

forEachFact(Class, Consumer)

forEachFact

default <T> void forEachFact(String type,
Predicate<T> filter,
Consumer<T> consumer)

A filtering version of the forEachFact(String, Consumer) method.

Type Parameters:

T - expected java type for the provided type name

Parameters:

type - expected fact type

consumer - consumer for the facts

filter - filtering predicate

See Also:

forEachFact(String, Consumer)

getParentContext

RuntimeContext<?> getParentContext()

fire

void fire()

fireAsync

<T> Future<T> fireAsync(T result)

Fires session asynchronously and returns a Future representing the session execution status.

Type Parameters:

T - result type parameter

Parameters:

result - the result to return by the Future

Returns:

a Future representing pending completion of the fire() command

Throws:

RejectedExecutionException - if the task cannot be scheduled for execution

fireAsync

default Future<S> fireAsync()

Same as fireAsync(Object), with the Future's get method will returning the session itself.

Returns:

a Future representing pending completion of the fire() command.

Throws:

RejectedExecutionException - if the task cannot be scheduled for execution

See Also:

fireAsync(Object)

close

void close()

Specified by:

close in interface AutoCloseable

clear

void clear()
