Deeploy.DeeployTypes.NodeMapper

class Deeploy.DeeployTypes.NodeMapper(parser: NodeParser, bindings: List[NodeBinding])

Bases: object

Deeploy class to link a NodeParser and several NodeBindings

Methods

__init__(parser: NodeParser, bindings: List[NodeBinding])

__init__(parser, bindings)
bind(ctxt, node)	Invokes the binder's bind method to setup the executionBlock and buffer hoisting
bindingsExhausted()	Returns whether all bindings have been tried
discardCurrentBinder()	Discards the binder object
generate(ctxt)	Generates the C Code of the binder elected by this mapper
resetDiscardedBindings()	Reset the discardedBindings set
typeCheck(ctxt, node)	Tries to elect a binder object whose typeChecker allows the node configuration

Attributes

parser	The NodeParser object which is used to determine whether an operator may be bound to one of the associated bindings
bindings	All possible bindings that correspond to the linked parser
binder	The currently chosen NodeBinding
bound	Indicates whether a binder has been chosen or not
discardedBindings	Set of all bindings which have been tried unsuccessfully.

parser

The NodeParser object which is used to determine whether an operator may be bound to one of the associated bindings

Type:

NodeParser

bindings

All possible bindings that correspond to the linked parser

Type:

List[NodeBinding]

binder: NodeBinding

The currently chosen NodeBinding

Type:

NodeBinding

bound

Indicates whether a binder has been chosen or not

Type:

bool

discardedBindings

Set of all bindings which have been tried unsuccessfully.

Type:

Set[NodeBinding]

bindingsExhausted() → bool

Returns whether all bindings have been tried

Returns:

True is no more bindings are possible

Return type:

bool

discardCurrentBinder()

Discards the binder object

resetDiscardedBindings()

Reset the discardedBindings set

typeCheck(ctxt: NetworkContext, node: Graph) → Tuple[NetworkContext, bool]

Tries to elect a binder object whose typeChecker allows the node configuration

Parameters:

• ctxt (NetworkContext) – Current NetworkContext

• node (gs.Graph) – The node that is being evaluated

Returns:

Updated NetworkContext and bool to indicate success or failure

Return type:

Tuple[NetworkContext, bool]

bind(ctxt: NetworkContext, node: Node) → Tuple[NetworkContext, List[str], bool]

Invokes the binder’s bind method to setup the executionBlock and buffer hoisting

Parameters:

• ctxt (NetworkContext) – Current NetworkContext

• node (gs.Node) – Node that should be bound

Returns:

Updated NetworkContext, list of hoisted TransientBuffers’ names, boolean to indicate success or failure

Return type:

Tuple[NetworkContext, List[str], bool]

generate(ctxt: NetworkContext) → List[str]

Generates the C Code of the binder elected by this mapper

Parameters:

ctxt (NetworkContext) – Current NetworkContext

Returns:

Returns a list of code snippets that correspond to the operator’s invocation

Return type:

List[str]

Raises:

RuntimeError – Raises a RuntimeError if no binder has been elected or the binder has not been bound yet.
