Defaults to MAX_CONCRETE_STRING_SIZE - 1 such that even with a null terminator all strings can be rendered concretely by string-refinement's get_array function, which is used by --trace among other C/JBMC options.

◆ max_nondet_tree_depth

size_t object_factory_parameterst::max_nondet_tree_depth = 5

Maximum depth of pointer chains (that contain recursion) in the nondet generated input objects.

Used to prevent the object factory from looping infinitely during the generation of code that allocates/initializes recursive data structures (such as a linked list). The object factory tracks the number of times a pointer has been dereferenced in a 'depth' counter variable. If a pointer to be initialized points to an object of a type that already occured on the current pointer chain, and if 'depth' is larger than 'max_nondet_tree_depth`, then the pointer is set to null. The parameter does not affect non-recursive data structures, which are always initialized to their full depth.

◆ min_nondet_string_length

size_t object_factory_parameterst::min_nondet_string_length = 0

Minimum value for the non-deterministically-chosen length of a string.

◆ min_null_tree_depth

size_t object_factory_parameterst::min_null_tree_depth = 0

To force a certain depth of non-null objects.

The default is that objects are 'maybe null' up to the nondet tree depth. Examples:

max_nondet_tree_depth=0, min_null_tree_depth irrelevant pointer initialized to null
max_nondet_tree_depth=n, min_null_tree_depth=0 pointer and children up to depth n maybe-null, beyond n null
max_nondet_tree_depth=n >=m, min_null_tree_depth=m pointer and children up to depth m initialized to non-null, children up to n maybe-null, beyond n null

◆ string_input_values

std::list<std::string> object_factory_parameterst::string_input_values

Force one of finitely many explicitly given input strings.

Definition at line 76 of file object_factory_parameters.h.

◆ string_printable

bool object_factory_parameterst::string_printable = false

Force string content to be ASCII printable characters when set to true.
