public class LongLongDataType extends AbstractSignedIntegerDataType
Basic implementation for an Signed LongLong Integer dataType

  • Field Details

    • dataType

      public static final LongLongDataType dataType
      A statically defined LongLongDataType instance.

  • Constructor Details

    • LongLongDataType

      public LongLongDataType()

    • LongLongDataType

      public LongLongDataType(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.

      Returns:
      the length of this DataType

    • hasLanguageDependantLength

      public boolean hasLanguageDependantLength()
      Description copied from interface: DataType
      Indicates if the length of this data-type is determined based upon the DataOrganization obtained from the associated DataTypeManager.
      Specified by:
      hasLanguageDependantLength in interface DataType
      Overrides:
      hasLanguageDependantLength in class AbstractDataType
      Returns:
      true length is language/compiler-specification dependent, else false

    • getDescription

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

    • getCDeclaration

      public String getCDeclaration()
      Overrides:
      getCDeclaration in class AbstractIntegerDataType
      Returns:
      the C style data-type declaration for this data-type. Null is returned if no appropriate declaration exists.

    • getOppositeSignednessDataType

      public UnsignedLongLongDataType getOppositeSignednessDataType()
      Specified by:
      getOppositeSignednessDataType in class AbstractIntegerDataType
      Returns:
      the data-type with the opposite signedness from this data-type. For example, this method on IntegerDataType will return an instance of UnsignedIntegerDataType.

    • clone

      public LongLongDataType 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.

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

    • getCTypeDeclaration

      public String getCTypeDeclaration(DataOrganization dataOrganization)
      Description copied from class: BuiltIn
      Returns null for FactoryDataType (which should never be used) and Dynamic types which should generally be replaced by a primitive array (e.g., char[5]) or, a primitive pointer (e.g., char *). For other types an appropriately sized unsigned integer typedef is returned.
      Specified by:
      getCTypeDeclaration in interface BuiltInDataType
      Overrides:
      getCTypeDeclaration in class BuiltIn
      Parameters:
      dataOrganization - or null for default
      Returns:
      definition C-statement (e.g., #define or typedef) or null if type name is a standard C-primitive name or if type is FactoryDataType or Dynamic.
