Constructor Detail

AbstractMemberExpansionTransformer

                                             T expr)

Method Detail

createIterationExpr

protected abstract IRExpression createIterationExpr(IType rootComponentType,
                                                    String identifierName,
                                                    IType identifierType,
                                                    IType compType)

Subclassers need only implement this method for the iteration expression i.e., the singular form of the expansion expr.

getPropertyOrMethodType

protected abstract IType getPropertyOrMethodType(IType rootComponentType,
                                                 IType compType)

compile_impl

protected IRExpression compile_impl()

Specified by:

compile_impl in class AbstractExpressionTransformer<T extends IMemberAccessExpression>

compileExpansionWithNoReturnValue

protected IRExpression compileExpansionWithNoReturnValue(IType rootType,
                                                         IType rootComponentType,
                                                         IType resultType,
                                                         IType resultCompType)

compileExpansionDirectlyToArray

protected IRExpression compileExpansionDirectlyToArray(IType rootType,
                                                       IType rootComponentType,
                                                       IType resultType,
                                                       IType resultCompType)

If this method is being called, it means we're expanding a one-dimensional array or collection, with a right hand side that evaluates to a property that's not an array or collection. In that case, we build up an array and simply store values directly into it. We also null-short-circuit in the event that the root is null. The member expansion portion ends up as a composite that looks like: temp_array = new Foo[temp_root.length] for (a in temp_root index i) { temp_array[i] = a.Bar } temp_array And the overall expression looks like: temp_root = root ( temp_root == null ? (Bar[]) null : (Bar[]) member_expansion )

compileExpansionUsingArrayList

protected IRExpression compileExpansionUsingArrayList(IType rootType,
                                                      IType rootComponentType,
                                                      IType resultType,
                                                      IType resultCompType,
                                                      IType propertyType)

This method will compile the expansion using an ArrayList to collect temporary results. This is appropriate if the right-hand-side is a Collection or array, if the root is an Iterable or Iterator or other object whose size can't easily be determined up-front, or if the root is a nested Collection or array that will require additional unwrapping. The overall result of the expansion thus looks like the following composite: temp_arraylist = new ArrayList() for (a in temp_root) { temp_arraylist.addAll( AbstractMemberExpansionTransform.arrayToCollection( a.Bars ) ) } AbstractMemberExpansionTransformer.listToArray(temp_array)
