Python Callable utilities.
For internal use only; no backwards-compatibility guarantees.
Represents a Python callable object with source codes before evaluated.
Proxy object to Store a callable object with its string form (source code). The string form is used when the object is encoded and transferred to foreign SDKs (non-Python SDKs).
Supported formats include fully-qualified names such as math.sin, expressions such as lambda x: x * x or str.upper, and multi-line function definitions such as def foo(x): … or class definitions like class Foo(…): …. If the source string contains multiple lines then lines prior to the last will be evaluated to provide the context in which to evaluate the expression, for example:
import math lambda x: x - math.sin(x)
is a valid chunk of source code.
