A representation of a function invocation in TFF's internal language.
Inherits From: ComputationBuildingBlock
, TypedObject
tff.framework.Call(
fn: tff.framework.ComputationBuildingBlock
,
arg: Optional[tff.framework.ComputationBuildingBlock
] = None
)
The call construct takes an argument struct with two elements, the first being
the function to invoke (represented as a computation with a functional result
type), and the second being the argument to feed to that function. Typically,
the function is either a TFF instrinsic, or a lambda expression.
The concise notation for calls is foo(bar)
, where foo
is the function,
and bar
is the argument.
Args |
fn
|
A value of a functional type that represents the function to invoke.
|
arg
|
The optional argument, present iff 'fn' expects one, of a type that
matches the type of 'fn'.
|
Raises |
TypeError
|
if the arguments are of the wrong types.
|
Attributes |
argument
|
|
function
|
|
proto
|
Returns a serialized form of this object as a pb.Computation instance.
|
type_signature
|
Returns the TFF type of this object (an instance of tff.Type ).

Methods
children
View source
children() -> Iterator[tff.framework.ComputationBuildingBlock
]
Returns an iterator yielding immediate child building blocks.
compact_representation
View source
compact_representation()
Returns the compact string representation of this building block.
View source
formatted_representation()
Returns the formatted string representation of this building block.
from_proto
View source
@classmethod
from_proto(
computation_proto: pb.Computation
) -> 'Call'
Returns an instance of a derived class based on 'computation_proto'.
Args |
computation_proto
|
An instance of pb.Computation.
|
Returns |
An instance of a class that implements 'ComputationBuildingBlock' and
that contains the deserialized logic from in 'computation_proto'.
|
Raises |
NotImplementedError
|
if computation_proto contains a kind of computation
for which deserialization has not been implemented yet.
|
ValueError
|
if deserialization failed due to the argument being invalid.
|
structural_representation
View source
structural_representation()
Returns the structural string representation of this building block.
__eq__
View source
__eq__(
other: object
) -> bool
Return self==value.
