Class MacintoshTimeStampDataType

  • All Implemented Interfaces:
    BuiltInDataType, DataType, ExtensionPoint

    public class MacintoshTimeStampDataType
    extends BuiltIn
    A datatype to interpret the Mac OS timestamp convention, which is based on the number of seconds measured from January 1, 1904.

    • Method Detail

      • 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.
      • 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
      • 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.
      • 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.
      • 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
