slang::analysis::ValueDriver class
#include <slang/analysis/ValueDriver.h>

Represents an expression that drives a value by assigning to some range of its type.

Constructors, destructors, conversion operators

ValueDriver(DriverKind kind, const ast::Expression& longestStaticPrefix, const ast::Symbol& containingSymbol, bitmask<DriverFlags> flags): Constructs a new ValueDriver instance.

bool isInputPort() const: Indicates whether the driver is for an input port.
bool isUnidirectionalPort() const: Indicates whether the driver is for a unidirectional port (i.e. not an inout or ref port).
bool isClockVar() const: Indicates whether the driver is for a clocking variable.
bool isInSingleDriverProcedure() const: Indicates whether the driver is inside a single-driver procedure (such as always_comb).
SourceRange getSourceRange() const: Gets the source range describing the driver as written in the source code.

not_null<const ast::Expression*> prefixExpression: The expression that drives the value.
not_null<const ast::Symbol*> containingSymbol: The symbol that contains the driver expression.
const ast::Expression* procCallExpression: If the driver is implied inside a procedure by a subroutine, this is the call expression for that subroutine.
bitmask<DriverFlags> flags: Flags that control how the driver operates.
DriverKind kind: The kind of driver (procedural or continuous).
DriverSource source: The source of the driver (procedural block, subroutine, etc).
bool isFromSideEffect: Indicates whether the driver is from a side effect of applying a cached instance body.
