Method Details

getSignatureInPredicateForm

public Predicate getSignatureInPredicateForm()

Create predicate from the context signature.

Overrides:

getSignatureInPredicateForm in class ArgumentBasedContext

Returns:

getDBE

public T getDBE()

Returns:

the DB Entry used in this context.

setDBE

public boolean setDBE(T dbe)

Parameters:

dbe - DB Entry to be used in this context.

Returns:

true if successfully set dbe otherwise false

addArgument

protected boolean addArgument(int roleIndex,
 Object value)

Add an argument to the list of arguments that were passed when the script was invoked.

Parameters:

roleIndex - the position at which to add the argument

value - the value to be assigned to the argument

Returns:

true if successful, false otherwise

addVarArgArgument

protected boolean addVarArgArgument(int roleIndex,
 Object value,
 int varArgCount)

Add a varArg argument to the Context, using the DBEntry role as a guide to populate the argument details.

Parameters:

roleIndex -

value -

varArgCount -

Returns:

setArgument

protected void setArgument(int pos,
 Object val)

Specify the (deep) value of an argument

Parameters:

pos - the position at which to add the argument

val - the value to which the argument should be bound

setupArguments

protected void setupArguments(Map<String,Object> bindings)

Goes through and binds the values in an event spec to arguments.

setupArguments

protected void setupArguments(List<? extends Object> inputArgs,
 List<? extends Object> returnArgs)

Goes through and binds the values in an event spec to arguments. Interprets each element according to its role.

Specified by:

setupArguments in class ArgumentBasedContext

collectArguments

public Collection<ActionBinding> collectArguments()

Collect arguments (not local vars) in the correct order to be passed into the primitive action method. This should only return the required args of primitive and return arg

Returns:

ordered primitive action arguments
