## Detailed Description

Base data table class, handles reading data files.

Base data table class--reads ASCII data files in various formats

1. Checks for the environment variable _envvar (defaults to "BABEL_DATADIR")

- Tries the _subdir directory if defined (def. "data") and then the main directory

1. Checks for the directory _dir (def. determined by the build environment)

- Tries the subdirectory corresponding to this version, then the main directory

1. Reverts to the compiled-in default data

## Constructor & Destructor Documentation

OBGlobalDataBase | ( |  | ) | `[inline]`

Constructor.

virtual ~OBGlobalDataBase | ( |  | ) | `[inline, virtual]`

Destructor.

## Member Function Documentation

void Init | ( |  | ) |

Read in the data file, falling back as needed.

virtual size_t GetSize | ( |  | ) | `[inline, virtual]`

Returns:
  the size of the database (for error checking)

Reimplemented in OBResidueData, OBTypeTable, OBIsotopeTable, OBElementTable, OBPhModel, OBRingTyper, OBRotorRules, OBAromaticTyper, OBAtomTyper, and OBBondTyper.

void SetReadDirectory | ( | char * | dir | ) | `[inline]`

Set the directory before calling Init()

void SetEnvironmentVariable | ( | char * | var | ) | `[inline]`

Set the environment variable to use before calling Init()

virtual void ParseLine | ( | const char * |  | ) | `[inline, virtual]`

Specified by particular table classes (parses an individual data line)

Reimplemented in OBResidueData, OBTypeTable, OBIsotopeTable, OBElementTable, OBPhModel, OBRingTyper, OBRotorRules, OBAromaticTyper, OBAtomTyper, and OBBondTyper.

## Member Data Documentation

bool _init`[protected]`

Whether the data been read already.

const char* _dataptr`[protected]`
