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

The current active value of this signal if it has width 1, as
a LogicValue.
no setteroverride

changed
→ Stream<
LogicValueChanged>

LogicValueChanged
events which triggers at most once per Simulator tick, iff the value of the Logic has changed.latefinal 
dstConnections
→ Iterable<
Logic>

Logic
s that are being directly driven bythis
.latefinal 
elements
→ List<
Logic>

latefinal

glitch
→ SynchronousEmitter<
LogicValueChanged> 
A stream of
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.

 isPort → bool

Returns true iff this signal is an input or output of its parent Module.
no setteroverride

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
LogicValueChanged
events which triggers at most once per Simulator tick, iff the value of the Logic has changed from1
to0
.no setteroverride 
nextChanged
→ Future<
LogicValueChanged> 
Triggers at most once, the next time that this Logic changes
value at the end of a Simulator tick.
no setteroverride

nextNegedge
→ Future<
LogicValueChanged>

value at the end of a Simulator tick from
1
to0
.no setteroverride

→ Future<
LogicValueChanged> 
Triggers at most once, the next time that this Logic changes
value at the end of a Simulator tick from
0
to1
.no setteroverride  packed → Logic

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

The Module that this Logic exists within.
getter/setter pairoverride
 parentStructure → LogicStructure?

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.

or(
) → Logic 
Unary OR.
override

override

put(

width = this.width *
multiplier
The inputmultiplier
cannot be negative or 0; an exception will be thrown, otherwise.override 
selectFrom(
List< Logic> busList, {Logic? defaultValue}) → Logic 
Performs a Logic
index
based selection on an List of Logic namedbusList
.override 
signExtend(
int newWidth) → Logic 
Returns a new Logic with width
newWidth
where new bits added are sign bits as the most significant bits. The sign is determined using two's complement, so it takes the most significant bit of the original signal and extends with that.override

startIndex
toendIndex
, both inclusive.override 
toString(
) → String

inherited

withSet(
int startIndex, Logic update) → Logic 
Returns a copy of this Logic with the bits starting from
startIndex
up untilstartIndex
+update
.width
set toupdate
instead of their original value.override 
xor(
) → Logic

override

zeroExtend(
int newWidth) → Logic 
Returns a new Logic with width
newWidth
where new bits added are zeros as the most significant bits.override
