value

public abstract Class value

Returns:

the context class to which the field is connected.

Default:

void.class

dynaSign

public abstract boolean dynaSign

Meaningful at methods only. It declares that the signature of the context method is dynamically derived from the types of the actual arguments.

Returns:

Default:

false

minOccurs

public abstract long minOccurs

Returns:

the minimal number of elements in the context that matches this reference. In the case of context methods it indicates the minimal number of calls invoked. In the case of context fields it indicates the minimum number of matching values in the context.

Default:

1L

maxOccurs

public abstract long maxOccurs

Returns:

the maximal number of elements in the context that matches this reference. In the case of context methods it indicates the maximal number of calls invoked. In the case of context fields it indicates the maximum number of matching values in the context.

Default:

1L

name

public abstract String name

Returns:

the name of the message which is emitted as soon as the annotated member is accessed. It corresponds to the name property of the ToContext annotation.

scope

public abstract MessageScope scope

Returns:

the scope of the emitted message. It determines which receivers will process the message. If a receiver is out of the scope it will not process the message.

Default:

local

aggregation

public abstract AggregationType aggregation

Returns:

Determines how multiple results of the context methods are aggregated

Default:

auto

async

public abstract boolean async

TODO - causes the message is processed asynchronously

Default:

false

transformer

public abstract Class<? extends ReplyTransformer> transformer

Returns:

the selector for selecting values from replies collected within a composite

org.iqual.chaplin.DefaultReplyTransformer.class

storage

public abstract Storage storage

Returns:

the storage where the field or method is looked for.

Default:

context

cache

public abstract CachingMode cache

Indicates the caching mode of the value after it has been obtained.

Returns:
