  • Constructor Details

    • AbstractPointerTypedefBuiltIn

      protected AbstractPointerTypedefBuiltIn(String name, DataType referencedDataType, int pointerSize, DataTypeManager dtm)
      Constructs a pointer-typedef. The category path will match that of the referencedDataType. Subclass may set various default settings which correspond to PointerTypeSettingsDefinition.
      Parameters:
      name - name of this pointer-typedef or null to force auto-name generation.
      referencedDataType - data type this pointer points to
      pointerSize - pointer size in bytes or -1 for default pointer size
      dtm - data-type manager whose data organization should be used
    • AbstractPointerTypedefBuiltIn

      protected AbstractPointerTypedefBuiltIn(String name, Pointer pointerDataType, DataTypeManager dtm)
      Constructs a pointer-typedef. The category path will match that of the pointerDataType. Subclass may set various default settings which correspond to PointerTypeSettingsDefinition.
      Parameters:
      name - name of this pointer-typedef or null to force auto-name generation.
      pointerDataType - associated pointer datatype (required)
      dtm - data-type manager whose data organization should be used
  • Method Details

    • enableAutoNaming

      public void enableAutoNaming()
      Description copied from interface: TypeDef
      Enable auto-naming for this typedef. This will force naming to reflect the name of associated datatype plus an attribute list which corresponds to any TypeDefSettingsDefinition settings which may be set.
      Specified by:
      enableAutoNaming in interface TypeDef
    • isAutoNamed

      public boolean isAutoNamed()
      Description copied from interface: TypeDef
      Determine if this datatype use auto-naming (e.g., see PointerTypedef). If true, any change to associated TypeDefSettingsDefinition settings or naming of the pointer-referenced datatype will cause a automatic renaming of this datatype.
      Specified by:
      isAutoNamed in interface TypeDef
      Returns:
      true if auto-named, else false.
    • getReferencedDataType

      protected DataType getReferencedDataType()
      Get the referenced datatype used to construct this datatype (datatype which pointer references).
      Returns:
      referenced datatype
    • getUniversalID

      public UniversalID getUniversalID()
      Description copied from interface: DataType
      Get the universal ID for this datatype.

      This value is intended to be a unique identifier across all programs and archives. The same ID indicates that two datatypes were originally the same one. Keep in mind names, categories, and component makeup may differ and have changed since there origin.

      Specified by:
      getUniversalID in interface DataType
      Overrides:
      getUniversalID in class BuiltIn
      Returns:
      datatype UniversalID
    • hasGeneratedNamed

      protected boolean hasGeneratedNamed()
    • isEquivalent

      public boolean isEquivalent(DataType obj)
      Description copied from interface: DataType
      Check if the given datatype is equivalent to this datatype.

      The precise meaning of "equivalent" is datatype dependent.
      NOTE: if invoked by a DB object or manager it should be invoked on the DataTypeDB object passing the other datatype as the argument.

      Specified by:
      isEquivalent in interface DataType
      Overrides:
      isEquivalent in class BuiltIn
      Parameters:
      obj - the datatype being tested for equivalence.
      Returns:
      true if the if the given datatype is equivalent to this datatype.
    • getName

      public String getName()
      Description copied from interface: DataType
      Get the name of this datatype.
      Specified by:
      getName in interface DataType
      Overrides:
      getName in class AbstractDataType
      Returns:
      the name
    • 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
    • getLength

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

      public DataType getDataType()

      Returns:
      the datatype which this typedef is based on (may be another TypeDef).
    • getBaseDataType

      public DataType getBaseDataType()
      Description copied from interface: TypeDef
      Returns the non-typedef dataType that this typedef is based on, following chains of typedefs as necessary.
      Specified by:
      getBaseDataType in interface TypeDef
      Returns:
      the datatype which this typedef is based on (will not be another TypeDef).

    • dependsOn

      public boolean dependsOn(DataType dt)
      Description copied from interface: DataType
      Check if this datatype depends on the existence of the given datatype.

      For example byte[] depends on byte. If byte were deleted, then byte[] would also be deleted.

      Specified by:
      dependsOn in interface DataType
      Overrides:
      dependsOn in class BuiltIn
      Parameters:
      dt - the datatype to test that this datatype depends on.

      true if the existence of this datatype relies on the existence of the specified datatype dt.

      Specified by:
      getValueClass in 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.
    • getValue

      public Object getValue(MemBuffer buf, Settings settings, int length)
      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.

      Specified by:
      getValue in interface DataType
      Parameters:
      buf - the data buffer.
      settings - the settings to use.
