Overrides:

getTerminals in class DatasetClauseTransformation

Returns:

the set

eval

public VTLValue eval(TransformationScheme scheme)

Description copied from interface: Transformation

Evaluates this transformation in the context of the given TransformationScheme.

Parameters:

scheme - the transformation scheme

Returns:

the result of the computation of this Transformation.

getMetadata

public DataSetMetadata getMetadata(TransformationScheme scheme)

Description copied from interface: Transformation

Checks and returns the metadata of this Transformation within the given TransformationScheme.

Parameters:

scheme - the transformation scheme

Returns:

the metadata of this Transformation.

computeMetadata

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Specified by:

hashCode in interface Transformation

Specified by:

hashCode in class DatasetClauseTransformation

equals

public boolean equals(Object obj)

Specified by:

equals in interface Transformation

Specified by:

equals in class DatasetClauseTransformation

computeLineage
