Synopsis

This module is a bag of unrelated mini-modules, classes and global functions. The following functional groups can be recognized:

• Object utilities:
  • ObjCompare objects with each other. A signature for comparison functions is defined (required for comparison functions used in the Sort class), and one such function is provided.
  • objcopy/objmove/objset copies objects from one place to another.
  • Mark objects as valid or invalid.
  • Notices provide basic support for shared access of data by various objects.
  • Sort objects on one or more keys, in ascending or descending order. Fast sorting is provided for certain types of objects.
  • Binary Search templated functions for sorted containers (ascending or descending order) are available.
  • Linear Search templated functions for unsorted containers are available.
• Logical utilities:
  • Assertion lets you throw an error when a condition in not fullfilled.
  • Bit vectors are an efficient method to keep True/False information on a set of items or conditions.
• Pointer utilities
  • Counted pointers provide support for reference counting.
  • Pointer holders can be used to hold allocated pointers which should be deleted when an exception is thrown.
• Datatype utilities
  • DataType enumerates the possible data types in the table system.
  • ValType describes the data types and their undefined values.
  • Register provides runtime typing information.
• Other utilities
  • Dynamic buffers are used to store data in dynamically allocated buffers.
  • Regular expressions are supported by the class Regex and the associated function library cregex.
  • Sequences of any datatype can be derived from the base class Sequence. One example is uIntSequence, provided for general use. Another is RegSequence, exclusively used by the Register function.
  • Strings. for the C++ preprocessor

You may want to look at the individual header files to see whether you might not prefer to include only the header files you really need; it may be more efficient to do so.
