    • Method Detail

      • clone

        public DataType clone​(DataTypeManager dtm)
        Description copied from interface: DataType
        Returns an instance of this DataType with its universalID and SourceArchive identity retained.

        The current instanceof 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.

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

      • getMnemonic

        public java.lang.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.

      • 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.

        Returns:
        the length of this DataType

      • getRepresentation

        public java.lang.String getRepresentation​(MemBuffer buf,
                                          Settings settings,
                                          int length)
        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 java.lang.Object getValue​(MemBuffer buf,
                                 Settings settings,
                                 int length)
        Description copied from interface: DataType
        Get the data in the form of the appropriate Object for this DataType.

        For instance if the datatype is an AddressDT, return an Address object. a Byte, return a Scalar* (maybe this should be a Byte) a Float, return a Float

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

      • encodeValue

        public byte[] encodeValue​(java.lang.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​(java.lang.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 java.lang.Class<?> getValueClass​(Settings settings)
        Description copied from interface: DataType
        Get the Class of the value to be returned by this datatype.
        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.
