```
public interface KSType

                    
```
Represents a type in Kotlin's type system.
Generally, a type is comprised of a declaration (e.g., class), corresponding type arguments, and other details like nullability. KSType is useful when doing type checking, finding the declaration, and so on. Some of the information, such as type annotations and type arguments, are often available in the corresponding type reference without resolution.

Method Summary

Modifier and Type	Method	Description
`abstract Boolean`	`isAssignableFrom(KSType that)`	Check whether this type is assign-compatible from another type.
`abstract Boolean`	`isMutabilityFlexible()`	True if the type is a collection and can be both mutable and immutable, depending on the context.
`abstract Boolean`	`isCovarianceFlexible()`	True if the type can be both invariant and covariant, depending on the context.
`abstract KSType`	`replace(List<KSTypeArgument> arguments)`	Replace the type arguments
`abstract KSType`	`starProjection()`	Returns the star projection of the type.
`abstract KSType`	`makeNullable()`	Make the type nullable
`abstract KSType`	`makeNotNullable()`	Make the type not nullable
`abstract KSDeclaration`	`getDeclaration()`	The declaration that generates this type.
`abstract Nullability`	`getNullability()`	A type can be nullable, not nullable, or context-specific in the case of platform types.
`abstract List<KSTypeArgument>`	`getArguments()`	Type arguments to the type.
`abstract Sequence<KSAnnotation>`	`getAnnotations()`	Type annotations to the type.
`abstract Boolean`	`getIsMarkedNullable()`	True if the type is explicitly marked as nullable type, i.e.
`abstract Boolean`	`getIsError()`	True if the type is an error type, which means the type can't be resolved by compiler.
`abstract Boolean`	`getIsFunctionType()`	True if the type is a function type.
`abstract Boolean`	`getIsSuspendFunctionType()`	True if the type is a suspend function

- Method Detail
  - isAssignableFrom
```
 abstract Boolean isAssignableFrom(KSType that)
```
    Check whether this type is assign-compatible from another type.
  - isMutabilityFlexible
```
 abstract Boolean isMutabilityFlexible()
```
    True if the type is a collection and can be both mutable and immutable, depending on the context.
  - isCovarianceFlexible
```
 abstract Boolean isCovarianceFlexible()
```
    True if the type can be both invariant and covariant, depending on the context.
  - replace
```
 abstract KSType replace(List<KSTypeArgument> arguments)
```
    Replace the type arguments
  - starProjection
```
 abstract KSType starProjection()
```
    Returns the star projection of the type.
  - makeNullable
```
 abstract KSType makeNullable()
```
    Make the type nullable
  - makeNotNullable
```
 abstract KSType makeNotNullable()
```
    Make the type not nullable
  - getDeclaration
```
 abstract KSDeclaration getDeclaration()
```
    The declaration that generates this type.
  - getNullability
```
 abstract Nullability getNullability()
```
    A type can be nullable, not nullable, or context-specific in the case of platform types.
  - getArguments
```
 abstract List<KSTypeArgument> getArguments()
```
    Type arguments to the type.
  - getAnnotations
```
 abstract Sequence<KSAnnotation> getAnnotations()
```
    Type annotations to the type.
  - getIsMarkedNullable
```
 abstract Boolean getIsMarkedNullable()
```
    True if the type is explicitly marked as nullable type, i.e. has question mark in type declaration.
  - getIsError
```
 abstract Boolean getIsError()
```
    True if the type is an error type, which means the type can't be resolved by compiler.
  - getIsFunctionType
```
 abstract Boolean getIsFunctionType()
```
    True if the type is a function type. Note that a suspend function will return false here.
  - getIsSuspendFunctionType
```
 abstract Boolean getIsSuspendFunctionType()
```
    True if the type is a suspend function
