Case class
A block of CaseItems where only the one with a matching CaseItem.value is executed.
Searches for which of items appropriately matches expression, then executes the matching CaseItem. If defaultItem is specified, and no other item matches, then that one is executed. Use conditionalType to modify behavior in ways similar to what is available in SystemVerilog.

Case(Logic expression, List<
CaseItem> items, {List<Conditional> ? defaultItem, ConditionalType conditionalType = ConditionalType.none}) - Whenever an item in items matches expression, it will be executed.
Properties
- caseType → String
-
Returns the SystemVerilog keyword to represent this case block.

conditionals
→ List<
Conditional> -
Lists of all
Conditionals directly contained within thisConditional(not including itself).latefinal - conditionalType → ConditionalType
-
The type of case block this is, for special attributes
(e.g. ConditionalType.unique, ConditionalType.priority).
final
-
defaultItem
→ List<
Conditional> ? -
The default to execute when there was no match with any other CaseItems.

drivers
→ List<
Logic> -
Lists all drivers, recursively including all sub-Conditionals drivers.
latefinal
- expression → Logic
-
A logical signal to match against.
final
- hashCode → int
-
The hash code for this object.

An ordered collection of
CaseItems to search through for a match to expression.final -
receivers
→ List<
Logic> -
Lists all receivers, recursively including all sub-Conditionals
receivers.

Methods
-
driverInput(
Logic driver) → Logic -
Gets the input port associated with
driver.inherited -
driverValue(
Logic driver) → LogicValue -

associated with
driver.inherited -
execute(
Set< Logic> drivenSignals, [void guard(Logic)?]) → void -
Executes the functionality of this Conditional and
populates
drivenSignalswith all Logics that were driven during execution.override -
getConditionals(
) → List< Conditional> -
Lists of all
Conditionals directly contained within thisConditional(not including itself).inherited -
getDrivers(
) → List< Logic> -
Lists all drivers, recursively including all sub-Conditionals drivers.
inherited
-
getReceivers(
) → List< Logic> -

-
isMatch(
LogicValue value, LogicValue expressionValue) → bool -
Returns true iff
valuematches the expressions current value. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
receiverOutput(
Logic receiver) → Logic -
Gets the output port associated with
receiver.inherited -
toString(
) → String -
