Interface PHPStan\Type\ConstantScalarType

`extends`	`Type`

A type whose value is known at analysis time — a compile-time constant scalar. Implemented by ConstantIntegerType, ConstantFloatType, ConstantStringType, ConstantBooleanType, and NullType. Use Type::isConstantValue() to check if a type is constant without instanceof, and Type::getConstantScalarTypes() to extract constant types from unions.
