LogicStructure(Iterable<
Logic> elements, {String? name}) 
Creates a new LogicStructure with
elements
as elements.
Properties
 arrayIndex → int?

If this is a part of a LogicArray, the index within that array.
Othwerise, returns
null
.no setteroverride  bit → LogicValue

a LogicValue.
no setteroverride

changed
→ Stream<
LogicValueChanged>

elements
→ List<
Logic>

glitch
→ SynchronousEmitter<

LogicValueChanged
events for every time the signal transitions at any time during a Simulator tick.latefinal  hashCode → int

The hash code for this object.
no setterinherited
 isArrayMember → bool

True if this is a member of a LogicArray.
no setteroverride
 isInput → bool

Returns true iff this signal is an input of its parent Module.
no setteroverride
 isOutput → bool

Returns true iff this signal is an output of its parent Module.

leafElements
→ List<
Logic> 
A list of all leaflevel elements at the deepest hierarchy of this
structure provided in index order.
latefinal
 name → String

The name of this signal.
final
 naming → Naming

Controls the naming (and renaming) preferences of this signal in generated
outputs.
no setteroverride

negedge
→ Stream<
LogicValueChanged> 
A Stream of

events which triggers at most once per Simulator tick, iff the value of the Logic has changed from1
to0
.no setteroverride 
nextChanged

value at the end of a Simulator tick.
no setteroverride

.no setteroverride  packed → Logic

Packs all elements into one flattened bus.
latefinal
 parentModule ↔ Module?

The Module that this Logic exists within.
getter/setter pairoverride

If this is a part of a LogicStructure, the structure which this is
a part of. Otherwise,
null
.no setteroverride 
posedge
→ Stream<
LogicValueChanged> 
A Stream of
LogicValueChanged
events which triggers at most once per Simulator tick, iff the value of the Logic has changed from0
to1
.no setteroverride  previousValue → LogicValue?

The value of this signal before the most recent Simulator.tick had
completed. It will be
null
before the first tick after this signal is created.no setteroverride  reversed → Logic

Returns a version of this Logic with the bit order reversed.
no setteroverride
 runtimeType → Type

A representation of the runtime type of the object.
no setterinherited
 srcConnection → Logic?

A LogicStructure never has a direct source driving it, only its
elements do, so always returns
null
.no setteroverride  structureName → String

Returns the name relative to the parentStructuredefined hierarchy, if
one exists. Otherwise, this is the same as name.
no setteroverride
 value → LogicValue

The current active value of this signal.
no setteroverride
 valueBigInt → BigInt

The current valid active value of this signal as a BigInt.
no setteroverride
 valueInt → int

The current valid active value of this signal as an int.
no setteroverride
 width → int

The number of bits in this signal.
