All Implemented Interfaces:
  `BuiltInDataType`, `DataType`, `Dynamic`, `ExtensionPoint`

@Deprecated public class RTTI1DataType extends RTTIDataType
Deprecated.
Use of this dynamic data type class is no longer recommended. Instead a BaseClassDescriptor structure data type can be obtained using the Rtti1Model.
The RTTI1 data type represents a BaseClassDescriptor structure.

Fields for this RunTimeTypeInformation structure can be found on http://www.openrce.org

     struct BaseClassDescriptor {
         4byte_ptr_or_disp pTypeDescriptor; // ref to TypeDescriptor (RTTI 0) for class
         dword numContainedBases;           // count of extended classes in BaseClassArray (RTTI 2)
         struct pmd where;                  // member displacement structure
         dword attributes;                  // bit flags
     }

     struct pmd {
         int mdisp; // member displacement
         int pdisp; // vbtable displacement
         int vdisp; // displacement within vbtable
     }

RTTI_Base_Class_Descriptor is the label for the RTTI1 data structure.

- ## Constructor Details

  - ### RTTI1DataType

    public RTTI1DataType()
    Deprecated.
    Creates a dynamic Base Class Descriptor data type.

  - ### RTTI1DataType

    public RTTI1DataType(DataTypeManager dtm)
    Deprecated.
    Creates a dynamic Base Class Descriptor data type.
    Parameters:
      `dtm` - the data type manager for this data type.

- ## Method Details

  - ### clone

    public DataType clone(DataTypeManager dtm)
    Deprecated.
    Description copied from interface: `DataType`
    Returns an instance of this DataType using the specified `DataTypeManager` to allow its use of the corresponding `DataOrganization` while retaining its unique identity (see `DataType.getUniversalID()` and archive association (see `DataType.getSourceArchive()`) if applicable.

    This instance will be returned if this datatype's DataTypeManager matches the specified dtm. The recursion depth of a clone will stop on any datatype whose `DataTypeManager` matches the specified dtm and simply use the existing datatype instance.

    NOTE: In general, this method should not be used to obtain an instance to be modified. In most cases changes may be made directly to this instance if supported or to a `DataType.copy(DataTypeManager)` of this type.

    Parameters:
      `dtm` - the data-type manager instance whose data-organization should apply.
    Returns:
      cloned instance which may be the same as this instance

  - ### getDescription

    public String getDescription()
    Deprecated.
    Description copied from interface: `DataType`
    Get a String briefly describing this DataType.
    Returns:
      a one-liner describing this DataType.

  - ### getMnemonic

    public String getMnemonic(Settings settings)
    Deprecated.
    Description copied from interface: `DataType`
    Get the mnemonic for this DataType.
    Specified by:
      `getMnemonic` in interface `DataType`
    Overrides:
      `getMnemonic` in class `AbstractDataType`
    Parameters:
      `settings` - settings which may influence the result or null
    Returns:
      the mnemonic for this DataType.

  - ### getLength

    public int getLength()
    Deprecated.
    Description copied from interface: `DataType`
    Get the length of this DataType as a number of 8-bit bytes.

    For primitive datatypes this reflects the smallest varnode which can be used to contain its value (i.e., raw data length).

    Example: For x86 32-bit gcc an 80-bit `long double` `raw data length` of 10-bytes will fit within a floating point register while its `aligned-length` of 12-bytes is used by the gcc compiler for data/array/component allocations to maintain alignment (i.e., `sizeof(long double)` ).

    NOTE: Other than the `VoidDataType`, no datatype should ever return 0, even if `DataType.isZeroLength()`, and only `Dynamic`/`FactoryDataType` datatypes should return -1. If `DataType.isZeroLength()` is true a length of 1 should be returned. Where a zero-length datatype can be handled (e.g., `Composite`) the `DataType.isZeroLength()` method should be used.

    Specified by:
      `getLength` in interface `DataType`
    Overrides:
      `getLength` in class `DynamicDataType`
    Returns:
      the length of this DataType

  - ### getRepresentation

    public String getRepresentation(MemBuffer buf, Settings settings, int length)
    Deprecated.
    Description copied from interface: `DataType`
    Get bytes from memory in a printable format for this type.
    Parameters:
      `buf` - the data.
      `settings` - the settings to use for the representation.
      `length` - the number of bytes to represent.
    Returns:
      the representation of the data in this format, never null.

  - ### getValue

    public Object getValue(MemBuffer buf, Settings settings, int length)
    Deprecated.
    Description copied from interface: `DataType`
    Returns the interpreted data value as an instance of the `advertised value class`.

    For instance, `Pointer` data types should return an Address object (or null), or integer data types should return a `Scalar` object.

    Parameters:
      `buf` - the data buffer
      `settings` - the settings to use.
      `length` - indicates the maximum number of bytes that may be consumed by a `Dynamic` datatype, otherwise this value is ignored. A value of -1 may be specified to allow a Dynamic datatype to determine the length based upon the actual data bytes
    Returns:
      the data object, or null if data is invalid

  - ### getAllComponents

    protected DataTypeComponent[] getAllComponents(MemBuffer buf)
    Deprecated.
    Description copied from class: `DynamicDataType`
    Get all dynamic components associated with the specified MemBuffer
    Specified by:
      `getAllComponents` in class `DynamicDataType`
    Parameters:
      `buf` - memory buffer positioned at start of data type instance
    Returns:
      all components or null if memory data is not valid for this data type.

  - ### getLength

    public int getLength(Memory memory, Address address, byte[] bytes)
    Deprecated.
    Gets the total length of the data created when this data type is placed at the indicated address in memory.
    Parameters:
      `memory` - the program memory for this data.
      `address` - the start address of the data.
      `bytes` - the bytes for this data.
    Returns:
      the length of the data. zero is returned if valid data can't be created at the indicated address using this data type.

  - ### getRtti0Address

    public Address getRtti0Address(Memory memory, Address rtti1Address)
    Deprecated.
    Gets the address of the RTTI 0 or null if one isn't indicated.
    Parameters:
      `memory` - the program memory containing the address
      `rtti1Address` - the address for the RTTI 1 that refers to the RTTI 0
    Returns:
      the address of the RTTI 0 or null.

  - ### getRtti0Address

    public Address getRtti0Address(Program program, Address rtti1Address)
    Deprecated.
    Gets the address of the RTTI 0 or null if one isn't indicated.
    Parameters:
      `program` - the program containing the address
      `rtti1Address` - the address for the RTTI 1 that refers to the RTTI 0
    Returns:
      the address of the RTTI 0 or null.

  - ### isValid

    public boolean isValid(Program program, Address startAddress, DataValidationOptions validationOptions)
    Deprecated.
    Description copied from class: `RTTIDataType`
    Determines if the data type is valid for placing at the indicated address in the program.
    Specified by:
      `isValid` in class `RTTIDataType`
    Parameters:
      `program` - the program
      `startAddress` - the address where the validated data type will be used to create data
      `validationOptions` - options indicating how to perform the validation
    Returns:
      true if this data type can be laid down at the specified address

  - ### getDefaultLabelPrefix

    public String getDefaultLabelPrefix()
    Deprecated.
    Description copied from interface: `DataType`
    Returns the appropriate string to use as the default label prefix in the absence of any data.
    Specified by:
      `getDefaultLabelPrefix` in interface `DataType`
    Overrides:
      `getDefaultLabelPrefix` in class `AbstractDataType`
    Returns:
      the default label prefix or null if none specified.
