Method Details

setSeed

public void setSeed(long seed)

Specified by:

setSeed in interface IEmgModule

Parameters:

seed - the seed to set

setUseSeed

public void setUseSeed(boolean useSeed)

Specified by:

setUseSeed in interface IEmgModule

Parameters:

useSeed - the useSeed to set

getNamedCreatedObjects

public Map<String,List<Object>> getNamedCreatedObjects()

Specified by:

getNamedCreatedObjects in interface IEmgModule

Returns:

the namedCreatedObjects

getImportConfiguration

public HashMap<String,Class<? extends IModule>> getImportConfiguration()

Overrides:

getImportConfiguration in class AbstractEplModule

prepareContext

protected void prepareContext()
                       throws EolRuntimeException

Overrides:

prepareContext in class EolModule

Throws:

EolRuntimeException

processRules

public Object processRules()
                    throws EolRuntimeException

Description copied from class: ErlModule

Main rule processing logic. Non-abstract for compatibility.

Overrides:

processRules in class AbstractEplModule

Returns:

The result of executing this module.

Throws:

EolRuntimeException

executeCreateOperations

protected void executeCreateOperations()
                                throws EolRuntimeException

Execute the create operations in the EMG script.

Throws:

EolModelElementTypeNotFoundException - the eol model element type not found exception

EolRuntimeException - If the type to be instantiated can't be found or any of the random functions fails.

match

public List<PatternMatch> match(Pattern pattern)
                         throws EolRuntimeException

Description copied from class: AbstractEplModule

This method provides the main high-level execution logic for EPL. The idea is that for each role in the pattern, appropriate bindings are made to the role and executed. Then the match block (and subsequently onMatch) is executed for the role and a PatternMatch is created where applicable.
In essence, this method can be thought of as the executor of all roles in the pattern, and therefore acts as a bridge between the high-level methods (e.g. AbstractEplModule.matchPatterns(int, PatternMatchModel)) and the low-level ones (e.g. AbstractEplModule.getRoleInstances(Role, String)).
Implementation-wise, this method delegates the main execution logic to AbstractEplModule.matchCombination(Collection, Pattern), and so the sole responsibility of this method is to loop through the combinations returned by AbstractEplModule.getCandidates(Pattern) and collect all the results. Subclasses may override this method to alter the type of collection returned and/or alter the looping mechanism.

Specified by:

match in interface IEplModule

Overrides:

match in class AbstractEplModule

Throws:

EolRuntimeException

getInt

protected int getInt(Object object)

Gets the int.

Parameters:

object - the object

Returns:

the int

getFloat

protected double getFloat(Object object)

Gets the float.

Parameters:

object - the object

Returns:

the float

containAny

protected boolean containAny(Collection<Object> first,
 Collection<Object> last)

Contain any.

Parameters:

first - the first

last - the last

Returns:

true, if successful
