Class RTTI4DataType

All Implemented Interfaces:
BuiltInDataType, DataType, Dynamic, ExtensionPoint

@Deprecated public class RTTI4DataType extends RTTIDataType
Deprecated.
Use of this dynamic data type class is no longer recommended. Instead a CompleteObjectLocator structure data type can be obtained using the Rtti4Model.
The RTTI4 data type represents a CompleteObjectLocator structure.

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

 struct CompleteObjectLocator {
     dword signature;
     dword offset;             // offset of vbtable within class
     dword cdOffset;           // constructor displacement offset
     4byte_ptr_or_disp pRtti0; // ref to TypeDescriptor (RTTI 0) for class
     4byte_ptr_or_disp pRtti3; // ref to ClassHierarchyDescriptor (RTTI 3)
 }
 

RTTI_Complete_Object_Locator is the label for the RTTI4 data structure.

    • RTTI4DataType

      public RTTI4DataType()
      Deprecated.
      Creates a dynamic Complete Object Locator data type.
    • RTTI4DataType

      public RTTI4DataType(DataTypeManager dtm)
      Deprecated.
      Creates a dynamic Complete Object Locator 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 shuold be made directly to this instance if supported or to a DataType.copy(DataTypeManager).

      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 (number of 8-bit bytes) of this DataType.

      NOTE: No datatype should ever return 0, even if DataType.isZeroLength(), and only Dynamic 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
      Get the interpretted data value in the form of the appropriate Object for this DataType. This method must return a value consistent with DataType.getValueClass(Settings).

      For instance, if this datatype is a Pointer an Address object or null should be returned. A Byte, returns a Scalar object.

      Parameters:
      buf - the data buffer.
      settings - the settings to use.
      length - the number of bytes to get the value from.
      Returns:
      the data Object.

      Returns:
      all components or null if memory data is not valid for this data type.
    • getLength

      rtti4Address - address of an RTTI4 structure
      Returns:
      the address of the RTTI0 structure or null.
    • getRtti3Address

      public Address getRtti3Address(Memory memory, Address rtti4Address)
      Deprecated.
      Gets the address of the RTTI3 that is referred to from an RTTI4 structure that is placed at the indicated address.
