package

pipda

</>

module

pipda.reference

</>

Provides Symbolic and Reference classes

Classes

• Reference(parent, ref) — The Reference class, used to define how it should be evaluatedaccording to the context for references, for example, f.A, f['A'] or the references of them (i.e. f.A.B, f.A['b'], etc) </>
• ReferenceAttr — Attribute references, for example: f.A, f.A.B etc.</>
• ReferenceItem — Subscript references, for example: f['A'], f.A['B'] etc</>

module

pipda.utils

</>

Provide utilities

Classes

• PipeableCallCheckWarning — Warns when checking verb is called normally or using piping</>
• MultiImplementationsWarning — Warns when multiple implementations are found</>
• PipeableCallCheckError — Raises when checking verb is called normally or using piping</>
• TypeHolder — A holder for a type that indicates the function passed toregister_verb or register_func is a placeholder (typically raising NotImplementedError), not a real implementation. </>

Functions

• evaluate_expr(expr, data, context) (any) — Evaluate a mixed expression</>
• has_expr(expr) (bool) — Check if expr has any Expression object in it</>
• is_piping(pipeable, fallback) (bool) — Check if the pipeable is called with piping.</>
• update_user_wrapper(x, name, qualname, doc, module) — Update the wrapper with user specified values</>

module

pipda.context

</>

Provides the context to evaluate f.A and f['A']

By default, 1. in the context of select, both f.A and f['A'] return 'A' 2. in the context of evaluation, f.A returns data.A and f['A'] returns data['A'] 3. when it is pending, you will need to evaluate args and kwargs yourself.

Classes

• ContextError — Any errors related to contexts</>
• ContextBase() — The context abstract class, defining howthe Reference objects are evaluated </>
• ContextSelect — Context used in a select context</>
• ContextEval — Context used in a data-evaluation context</>
• ContextPending — Pending context, don't evaluate the expression,awaiting next avaiable context </>
• Context — Context to solve f.A and f['A']</>

module

pipda.operator

</>

Provide operators

Classes

• OperatorCall — The operator call</>
• Operator — Defines the operators</>

Functions

• register_operator(opclass) — Register a operator class</>

module

pipda.expression

</>

Provides the abstract class Expression

Classes

• Expression() — The abstract Expression class</>

Functions

• register_array_ufunc(func) — Register a function to be used as array_ufunc on Expression</>
