Constructor & Destructor Documentation

◆ guard_exprt()

guard_exprt::guard_exprt ( const exprt e,
guard_expr_managert  
)
inlineexplicit

Construct a BDD from an expression The guard_managert parameter is not used, but we keep it for uniformity with other implementations of guards which may use it.

Definition at line 32 of file guard_expr.h.

Member Function Documentation

◆ add()

void guard_exprt::add ( const exprt expr)

Definition at line 40 of file guard_expr.cpp.

◆ append()

void guard_exprt::append ( const guard_exprt guard)
inline

Definition at line 44 of file guard_expr.h.

◆ as_expr()

exprt guard_exprt::as_expr ( ) const
inline

Definition at line 49 of file guard_expr.h.

◆ disjunction_may_simplify()

bool guard_exprt::disjunction_may_simplify ( const guard_exprt other_guard)

Returns true if operator|= with other_guard may result in a simpler expression.

For guard_exprt in practice this means they're both conjunctions, since for other things we just OR them together.

Definition at line 93 of file guard_expr.cpp.

◆ guard_expr()

exprt guard_exprt::guard_expr ( exprt  expr) const

Return guard => dest or a simplified variant thereof if either guard or dest are trivial.

bool guard_exprt::is_false ( ) const
inline

Definition at line 68 of file guard_expr.h.

Member Data Documentation

◆ expr

private

Definition at line 82 of file guard_expr.h.

◆ is_always_simplified

constexpr bool guard_exprt::is_always_simplified = false
staticconstexpr

The result of as_expr is not always in a simplified form and may requires some simplification.

This can vary according to the guard implementation.
