Class BoundMethodObjectInternal

A bound-method. Note that built-in methods, such as [].append are also represented as bound-methods. Although built-in methods and bound-methods are distinct classes in CPython, their behavior is the same and we treat them identically.

Direct supertypes

Predicates

callResult

Holds if obj is the result of calling this and origin is the origin of obj.

callResult

Holds if obj is the result of calling this and origin is the origin of obj with callee context callee.

calleeAndOffset

Holds if the function scope is called when this object is called and paramOffset is the difference from the parameter position and the argument position. For a normal function paramOffset is 0. For classes and bound-methods it is 1. Used by points-to to help determine flow from arguments to parameters.

contextSensitiveCallee
descriptorGetClass

Holds if the result of attribute access on the class holding this descriptor is value, originating at origin For example, although T.__dict__['name'] = classmethod(f), T.name is a bound-method, binding f and T

descriptorGetInstance

Holds if the result of attribute access on an instance of a class holding this descriptor is value, originating at origin For example, with T.__dict__['name'] = classmethod(f), T().name is a bound-method, binding f and T

functionAndOffset

Holds if the object function is called when this object is called and paramOffset is the difference from the parameter position and the argument position. For a normal function paramOffset is 0. For classes and bound-methods it is 1. This is used to implement the CallableValue public API.

getACall

Gets a call to this callable from the given context

getBuiltin

Gets the Builtin for this object, if any. Objects (except unknown and undefined values) should attempt to return exactly one result for either this method or getOrigin().

getClass

Gets the class of this object.

getFunction
getName

Gets the name of this of this object if it has a meaningful name. Note that the name of an object is not necessarily the name by which it is called For example the function named posixpath.join will be called os.path.join.

getOrigin

Gets a control flow node that represents the source origin of this object, if it has a meaningful location in the source code. This method exists primarily for providing backwards compatibility and locations for source objects. Source code objects should attempt to return exactly one result for this method.

getParameter

Gets the nth parameter node of this callable.

getParameterByName

Gets the named parameter node of this callable. Will not return the parameter node for self, instead use getSelfParameter.

getScope

Gets the scope of this callable if it has one

getSelf
getSelfParameter

Gets the parameter node that will be used for self.

introducedAt

Holds if this object is introduced into the code base at node given the context This means that node, in context, points-to this object, but the object has not flowed there from anywhere else. Examples: * The object None is “introduced” by the keyword “None”. * A bound method would be “introduced” when relevant attribute on an instance is accessed. In x = X(); x.m x.m introduces the bound method.

isDescriptor

Holds if this object is a descriptor. Holds, for example, for functions and properties and not for integers.

isNotSubscriptedType
neverReturns
notTestableForEquality

True if this “object” can be meaningfully analyzed to determine the boolean value of equality tests on it. For example, None or int can be, but int() or an unknown string cannot.

toString

Gets a textual representation of this element.

useOriginAsLegacyObject

Holds if this ‘object’ represents an entity that should be exposed to the legacy points_to API This should hold for almost all objects that do not have an underlying DB object representing their source, for example super objects and bound-method. This should not hold for objects that are inferred to exists by an import statements or the like, but which aren’t in the database.

Inherited predicates

attribute

Holds if the result of getting the attribute name is value and that value comes from origin. Note this is not the same as class lookup. For example for an object x the attribute name (x.name) may refer to a bound-method, an attribute of the instance, or an attribute of the class.

from CallableObjectInternal
attributesUnknown

Holds if the attributes of this object are wholly or partly unknowable

from CallableObjectInternal
binds

Holds if attribute lookup on this object may “bind” instance to descriptor. Here “bind” means that instance is passed to the descriptor.__get__() method at runtime. The term “bind” is used as this most likely results in a bound-method.

from CallableObjectInternal
booleanValue

Gets the boolean value of this object. This may be both true and false if the “object” represents a set of possible objects.

from CallableObjectInternal
getACall

Gets a call to this callable

from CallableObjectInternal
getClassDeclaration

Gets the class declaration for this object, if it is a class with a declaration.

from CallableObjectInternal
getIterNext

Gets the ‘object’ resulting from iterating over this object. Used in the context for i in this:. The result is the ‘object’ assigned to i.

from CallableObjectInternal
getSource

For backwards compatibility shim – Not all objects have a “source”. Objects (except unknown and undefined values) should attempt to return exactly one result for this method.

from ObjectInternal
hasAttribute

Holds if this value has the attribute name

from ObjectInternal
intValue

Gets the integer value of things that have integer values and whose integer value is tracked. That is, some ints, mainly small numbers, and bools.

from CallableObjectInternal
isBuiltinfrom ObjectInternal
isClass

True if this “object” is a class. That is, its class inherits from type

from CallableObjectInternal
length

Gets the length of the sequence that this “object” represents. Always returns a value for a sequence, will be -1 if the object has no fixed length.

from CallableObjectInternal
strValue

Gets the string value of things that have string values. That is, strings.

from CallableObjectInternal
subscriptUnknown

Holds if the result of subscripting this object are wholly or partly unknowable
