public Encounter()

Method Detail

setLimitFlag

public void setLimitFlag(boolean limitFlag)

Sets the flag that indicates whether the encounter should stop after a fixed number of symbols.

limitFlag - The limit flag

setStreamAdapter

public void setStreamAdapter(StreamAdapter streamAdapter)

Sets the stream adapter that provides the symbols for this encounter.

Parameters:

streamAdapter - The stream adapter

setInteractionContextUri

public void setInteractionContextUri(String interactionContextUri)

Sets the URI to use for the interaction context. If there is already an interaction context with this URI in the data source, then is will be re-used and extended. If not, a new interaction context will be created.

Parameters:

interactionContextUri - The URI of the interaction context to use

setAutoExtendLimit

public void setAutoExtendLimit(int autoExtendLimit)

Sets the maximum depth of nodes that will be marked extensible. (see Node.getExtensible()) by the encounter (rather than relying on the optimizer to manage the extensibility of nodes).

Parameters:

autoExtendLimit - The maximum depth of nodes that will be marked extensible

getLastVersion

public Version getLastVersion()

Returns the last ModelType.COUNTED version that was created by this encounter.

Specified by:

getLastVersion in interface Encounter

Returns:

the last version that was created by this encounter

command

@Transactional(propagation=REQUIRED,
               readOnly=false)
public void command(String... args)

Feeds the given files to the LEIA system.

Specified by:

command in interface Command

Parameters:

args - The paths of the files to feed

stateToString

public String stateToString(Collection<DirectedSymbol> state)

Returns a string representation of the given state

Parameters:

state - The state to represent

Returns:

The representation of the given state
