Method Detail

• findMatch

  OpCandidate findMatch(OpEnvironment ops,
                        OpRef ref)

  Finds and initializes the best module matching the given op name and/or type + arguments. An OpCandidate containing the matching module will be returned.

  Parameters:

  ops - The pool from which candidate ops should be drawn.

  ref - The op reference describing the op to match.

  Returns:

  An OpCandidate containing the module which wraps the best Op, with populated inputs, ready to run.

  Throws:

  IllegalArgumentException - if there is no match, or if there is more than one match at the same priority.

• findMatch

  OpCandidate findMatch(OpEnvironment ops,
                        List<OpRef> refs)

  Finds and initializes the best module matching any of the given op name and/or type + arguments. An OpCandidate containing the matching module will be returned.

  Parameters:

  ops - The pool from which candidate ops should be drawn.

  refs - The op references describing the op to match.

  Returns:

  An OpCandidate containing the module which wraps the best Op, with populated inputs, ready to run.

  Throws:

  IllegalArgumentException - if there is no match, or if there is more than one match at the same priority.

• findCandidates

  List<OpCandidate> findCandidates(OpEnvironment ops,
                                   OpRef ref)

  Builds a list of candidate ops which might match the given op reference.

  Parameters:

  ops - The pool from which candidate ops should be drawn.

  ref - The op reference describing the op to match.

  Returns:

  The list of candidate operations.

• findCandidates

  List<OpCandidate> findCandidates(OpEnvironment ops,
                                   List<OpRef> refs)

  Builds a list of candidate ops which might match one of the given op references.

  Parameters:

  ops - The pool from which candidate ops should be drawn.

  refs - The op references describing the op to match.

  Returns:

  The list of candidate operations.

• filterMatches

  List<OpCandidate> filterMatches(List<OpCandidate> candidates)

  Filters a list of ops to those matching the given arguments.

  Parameters:

  candidates - The list of op candidates to scan for matches.

  Returns:

  The list of matching op candidates, with associated Module instances attached.

• match

  Module match(OpCandidate candidate)

  Attempts to match the given arguments to the Op described by the specified ModuleInfo.

  Returns:

  A populated Module instance for the matching Op, or null if the arguments do not match the Op.

• typesMatch

  boolean typesMatch(OpCandidate candidate)

  Checks that each parameter is type-compatible with its corresponding argument.

• padArgs

  Object[] padArgs(OpCandidate candidate)

  Checks the number of args, padding optional args with null as needed.

• assignInputs

  Module assignInputs(Module module,
                      Object... args)

  Assigns arguments into the given module's inputs.
