PREALLOCATE_OUTPUTS

class Future(*args, domain=None, out=None)

Base class for deferred operations on data.

Parameters

• *args (Operands) – Operands. Number must match class attribute arity, if present.

• out (data, optional) – Output data object. If not specified, a new object will be used.

Notes

Operators are stacked (i.e. provided as arguments to other operators) to construct trees that represent compound expressions. Nodes are evaluated by first recursively evaluating their subtrees, and then calling the operate method.

arity

store_last = False

reset()

Restore original arguments.

atoms(*types, include_out=False)

has(*atoms)

replace(old, new)

Replace an object in the expression tree.

evaluate(id=None, force=True)

Recursively evaluate operation.

attempt(id=None)

Recursively attempt to evaluate operation.

meta()

meta_dirichlet(axis)

abstract meta_constant(axis)

abstract meta_parity(axis)

abstract meta_envelope(axis)

abstract check_conditions()

Check that all argument fields are in proper layouts.

abstract operate(out)

Perform operation.

as_ncc_operator(frozen_arg_basis_meta, cutoff, max_terms, cacheid=None)

class FutureScalar(*args, domain=None, out=None)

Class for deferred operations producing a Scalar.

future_type

meta

class FutureArray(*args, domain=None, out=None)

Class for deferred operations producing an Array.

future_type

class FutureField(*args, domain=None, out=None)

Class for deferred operations producing a Field.

future_type

static parse(string, namespace, domain)

Build FutureField from a string expression.

static cast(input, domain)

Cast an object to a FutureField.

unique_domain(*args)

Return unique domain from a set of fields.
