public class WideChar16DataType extends BuiltIn implements ArrayStringable, DataTypeWithCharset
  • Field Details

      public static final WideChar16DataType dataType
      A statically defined WideCharDataType instance.
  • Constructor Details

      public WideChar16DataType(DataTypeManager dtm)
  • Method Details

    • getLength

      public int getLength()
      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
      Returns:
      the length of this DataType
    • getDescription

      public String getDescription()
      Description copied from interface: DataType
      Get a String briefly describing this DataType.
      Specified by:
      getDescription in interface DataType
      Returns:
      a one-liner describing this DataType.
    • clone

      public DataType clone(DataTypeManager dtm)
      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.

      Specified by:
      clone in interface DataType
      Parameters:
      dtm - the data-type manager instance whose data-organization should apply.
      Returns:
      cloned instance which may be the same as this instance
    • getMnemonic

      public String getMnemonic(Settings settings)
      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.
    • getBuiltInSettingsDefinitions

      protected SettingsDefinition[] getBuiltInSettingsDefinitions()
      Description copied from class: BuiltIn
      Gets a list of all the settingsDefinitions used by this datatype.
      Overrides:
      getBuiltInSettingsDefinitions in class BuiltIn
      Returns:

    • getRepresentation

      public String getRepresentation(MemBuffer buf, Settings settings, int length)
      Description copied from interface: DataType
      Get bytes from memory in a printable format for this type.
      Specified by:
      getRepresentation in interface DataType
      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)
      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.

      Specified by:
      getValue in interface DataType
      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
    • isEncodable

      public boolean isEncodable()
      Description copied from interface: DataType
      Check if this type supports encoding (patching)

      If unsupported, DataType.encodeValue(Object, MemBuffer, Settings, int) and DataType.encodeRepresentation(String, MemBuffer, Settings, int) will always throw an exception. Actions which rely on either encode method should not be displayed if the applicable datatype is not encodable.

      Specified by:
      isEncodable in interface DataType
      Overrides:
      isEncodable in class AbstractDataType
      Returns:
      true if encoding is supported
    • encodeValue

      public byte[] encodeValue(Object value, MemBuffer buf, Settings settings, int length) throws DataTypeEncodeException
      Description copied from interface: DataType
      Encode bytes from an Object appropriate for this DataType.

      Converts the given object to the byte encoding and returns it. When appropriate, this should seek the nearest encoding to the specified value, since the object may come from a user script. For example, a floating-point value may be rounded. Invalid values should be rejected with a DataTypeEncodeException.

      Specified by:
      encodeValue in interface DataType
      Overrides:
      encodeValue in class AbstractDataType
      Parameters:
      value - the desired value.
      buf - a buffer representing the eventual destination of the bytes.
      settings - the settings to use.
      length - the expected length of the result, usually the length of the data unit, or -1 to let the type choose the length. It may be ignored, e.g., for fixed-length types.
      Returns:
      the encoded value.
      Throws:
      DataTypeEncodeException - if the value cannot be encoded for any reason, e.g., incorrect type, not enough space, buffer overflow, unsupported (see DataType.isEncodable()).
    • encodeRepresentation

      public byte[] encodeRepresentation(String repr, MemBuffer buf, Settings settings, int length) throws DataTypeEncodeException
      Description copied from interface: DataType
      Encode bytes according to the display format for this type.

      Converts the given representation to the byte encoding and returns it. When appropriate, this should seek the nearest encoding to the specified value, since the representation is likely coming from user input. For example, a floating-point value may be rounded. Invalid representations should be rejected with a DataTypeEncodeException.

      Specified by:
      encodeRepresentation in interface DataType
      Overrides:
      encodeRepresentation in class AbstractDataType
      Parameters:
      repr - the representation of the desired value, as in DataType.getRepresentation(MemBuffer, Settings, int). The supported formats depend on the specific datatype and its settings.
      buf - a buffer representing the eventual destination of the bytes.
      settings - the settings to use for the representation.
      length - the expected length of the result, usually the length of the data unit, or -1 to let the type choose the length. It may be ignored, e.g., for fixed-length types.
      Returns:
      the encoded value.
      Throws:
      DataTypeEncodeException - if the value cannot be encoded for any reason, e.g., incorrect format, not enough space, buffer overflow, unsupported (see DataType.isEncodable()).
    • getValueClass

      public Class<?> getValueClass(Settings settings)
      Description copied from interface: DataType

      Overrides:
      getValueClass in class DataTypeImpl
      Parameters:
      settings - the relevant settings to use or null for default.
      Returns:
      Class of the value to be returned by this datatype or null if it can vary or is unspecified. Types which correspond to a string or char array will return the String class.
