how to generate string const in z3 through java-api

问题

In z3's Java API, you can generate a string constant using ctx.mkString("a"). However, there is no direct equivalent to ctx.mkStringConst("a") as in Python.

英文:

How can I generate string const in z3 through java-api? For integer, there are ctx.mkInt(int a) generate an IntExpr with value a and ctx.mkIntConst("a") generate an IntExpr with name "a". However, for string, I can only find ctx.mkString("a"), which is just a SeqExpr with value "a" similar as ctx.mkInt. So what I want is something like ctx.mkStringConst("a") but there is no such function.

I find in python api, what I want is is simply str = String("a")

尝试以下。

String variable_name = "foo";
Expr variable = context.mkConst(context.mkSymbol(variable_name), context.mkStringSort());

Try the following.

String variable_name="foo";
Expr variable = context.mkConst(context.mkSymbol(variable_name), context.mkStringSort());
