    Modifier and Type
    Method
    Description
    int
    getCode()

    boolean
    isRefType()
    If the type is a reference type.
    boolean
    isSubTypeOf(AnyType other)
    Check if this is a sub type of given type.

  • Method Details

    • getCode

      int getCode()
      The type code(typeidx) in WebAssembly. Predefined types have an negative typeidx. Custom types have the positive index in the type section.
      Returns:
      the code

    • isRefType

      boolean isRefType()
      If the type is a reference type. A GC reference to the heap.
      Returns:
      true, is GC type

    • isSubTypeOf

      boolean isSubTypeOf(@Nonnull AnyType other)
      Check if this is a sub type of given type.
      Parameters:
      other - type to check
      Returns:
      true, if both are identical or this is a sub type of other. Or if other is a parent type of this.
