Method Detail

eval

public VTLValue eval(TransformationScheme session)

Description copied from interface: Transformation

Evaluates this transformation in the context of the given TransformationScheme.

Parameters:

session - the transformation scheme

Returns:

the result of the computation of this Transformation.

isTerminal

public boolean isTerminal()

Returns:

True if this Transformation do not require previous computations before returning a result.

getTerminals

public Set<LeafTransformation> getTerminals()

Description copied from interface: Transformation

A set of all the LeafTransformations recursively referenced by this Transformation. The set is empty if Transformation.isTerminal() is true.

Returns:

the set
