Method Detail

getIdentifiers

public String[] getIdentifiers()

Specified by:

getIdentifiers in class PrimitiveStackMapping

getParameters

public PrimitiveStackMapping.Parameter[] getParameters()

Specified by:

getParameters in class PrimitiveStackMapping

getComment

public String getComment()

Specified by:

getComment in class PrimitiveStackMapping

Returns:

a comment about the primitive. May be null.

apply

public void apply(RippleList arg,
         Sink<RippleList> solutions,
         ModelConnection mc)
           throws RippleException

Description copied from interface: Mapping

Applies the mapping to a single argument, producing zero or more solutions and passing them into a downstream Sink

Parameters:

arg - the argument data item

solutions - the solutions the argument is mapped to

mc - a helper object providing context (may be null)

Throws:

RippleException - if a data handling error occurs

getInverse

public StackMapping getInverse()
                        throws RippleException

Specified by:

getInverse in interface StackMapping

Overrides:

getInverse in class PrimitiveStackMapping

Returns:

the StackMapping exactly inverse to this mapping, or a NullMapping if no such mapping can be defined.

Throws:

RippleException - if the inverse cannot be determined
