DatatypeDecl 

class DatatypeDecl 

A cvc5 datatype declaration. A datatype declaration is not itself a datatype (see Datatype ), but a specification for creating a datatype sort.

The interface for a datatype declaration coincides with the syntax for the SMT-LIB 2.6 command declare-datatype , or a single datatype within the declare-datatypes command.

Datatype sorts can be constructed from a DatatypeDecl using:

• Solver::mkDatatypeSort()

• Solver::mkDatatypeSorts()

Public Functions

DatatypeDecl ( ) 

Constructor.

~DatatypeDecl ( ) 

void addConstructor ( const DatatypeConstructorDecl & ctor ) 

Add datatype constructor declaration.

Parameters :

ctor – The datatype constructor declaration to add.

size_t getNumConstructors ( ) const 

Returns :

True if this datatype declaration is resolved.

bool isNull ( ) const 

Determine if this datatype declaration is nullary.

Returns :

True if this DatatypeDecl is a null object.

std :: string toString ( ) const 
