public class AssemblyHiddenConstructStateGenerator
extends AssemblyConstructStateGenerator

The generator of AssemblyConstructState for a hidden sub-table operand

In short, this exhausts all possible constructors in the given sub-table. For well-designed languages, such exhaustion produces a very small set of possibilities. In general, hidden sub-table operands are a bad idea.

AssemblyHiddenConstructStateGenerator

public AssemblyHiddenConstructStateGenerator(AbstractAssemblyTreeResolver<?> resolver,
 SubtableSymbol subtableSym,
 AssemblyResolvedPatterns fromLeft)

Construct the hidden sub-table operand state generator

Parameters:

resolver - the resolver

subtableSym -

fromLeft - the accumulated patterns from the left sibling or the parent

Method Details

generate

public Stream<AssemblyGeneratedPrototype> generate(AbstractAssemblyStateGenerator.GeneratorContext gc)

Description copied from class: AbstractAssemblyStateGenerator

Generate states

Overrides:

generate in class AssemblyConstructStateGenerator

Parameters:

gc - the generator context for this node

Returns:

the stream of prototypes, each including accumulated patterns

getFiller

protected AssemblyParseTreeNode getFiller()

orderOpNodes

protected List<AssemblyParseTreeNode> orderOpNodes(AssemblyConstructorSemantic sem)

Description copied from class: AssemblyConstructStateGenerator

Arrange the branch's (mnemonic) children according to the machine-code production

This orders the parsed children so that each is readily paired to its operand as given by Constructor.getOperand(int).

Overrides:

orderOpNodes in class AssemblyConstructStateGenerator

Parameters:

sem - the SLEIGH constructor whose machine-code production to consider

Returns:

the children arranged in constructor operand order
