Detailed Description

class for auxiliary parameters associated with func_decl The class is initialized with a func_decl or application expression and an index The accessor get_expr, get_sort, ... is available depending on the value of kind(). The caller is responsible to check that the kind of the parameter aligns with the call (get_expr etc).

Parameters are available on some declarations to contain additional information that is not passed as arguments when a function is applied to arguments. For example, bit-vector extraction has two integer parameters. Array map has a function parameter.
