Detailed Description

FragmentDB - fragment database class. The fragment database is used to store commonly used subunits as amino acids, sugars and the like. They are entered in a special format described below. The main resource file resides under data/fragments/Fragments.db.

Member Typedef Documentation

typedef StringHashMap<String> BALL::FragmentDB::NameMap

A hash map used to convert one atom naming convention to another

Definition at line 76 of file fragmentDB.h.

typedef short BALL::FragmentDB::Type

Type definition for the fragment type

Definition at line 74 of file fragmentDB.h.

Member Enumeration Documentation

enum BALL::FragmentDB::FragmentTypes

Fragment types

Enumerator:

TYPE__UNKNOWN
TYPE__FRAGMENT
TYPE__RESIDUE
TYPE__MOLECULE

Definition at line 59 of file fragmentDB.h.

Constructor & Destructor Documentation

BALL::FragmentDB::FragmentDB ( )

Creates a default but invalid FragmentDB instance.

BALL::FragmentDB::FragmentDB ( const String & filename )

Creates a FragmentDB object and reads the contents of filename. If filename is an empty string, the default value "fragments/Fragments.db" is used.

Exceptions:

Exception::FileNotFound

if the file is not found in the BALL_DATA_PATH

BALL::FragmentDB::FragmentDB	(	const FragmentDB &	db,
		bool	deep = `true`
	)

Copy constructor.

virtual BALL::FragmentDB::~FragmentDB ( ) [virtual]

Destructor.

Member Function Documentation

Position BALL::FragmentDB::addNewFragment_ ( Residue * fragment ) [private]

Add a new fragment pointer to the database (while parsing)

void BALL::FragmentDB::destroy ( )

bool BALL::FragmentDB::expandFirst_ ( ResourceEntry & root_entry ) [private]

void BALL::FragmentDB::expandTree_ ( ResourceEntry & root_entry ) [private]

std::vector<String> BALL::FragmentDB::getAvailableNamingStandards ( ) const

Return a vector of available naming standards

const String& BALL::FragmentDB::getDefaultNamingStandard ( ) const

Return the default naming standard

const String& BALL::FragmentDB::getFilename ( ) const

Get the filename.

const Fragment* BALL::FragmentDB::getFragment ( const String & fragment_name ) const

Return a fragment.

Fragment* BALL::FragmentDB::getFragmentCopy ( const String & fragment_name ) const

Return a copy of a fragment. If a fragment with name fragment_name exists in the fragment database, a copy is created and returned. Otherwise, a null pointer is returned. Take care to destruct the copy again to avoid memory leaks.

Returns:: a pointer to the copied fragment or 0

Parameters:

fragent_name

the name of the fragment in the database

const std::vector<Residue*>& BALL::FragmentDB::getFragments ( ) const [inline]

Definition at line 158 of file fragmentDB.h.

FragmentDB::Type BALL::FragmentDB::getFragmentType ( const String & fragment_name ) const

Return a fragment.

Molecule* BALL::FragmentDB::getMoleculeCopy ( const String & fragment_name ) const

Return a copy of a fragment as a molecule. If a fragment with name fragment_name exists in the fragment database, a copy is created, inserted into a new molecule, and returned. Otherwise, a null pointer is returned. Take care to destruct the copy again to avoid memory leaks.

Returns:: a pointer to the copied fragment or 0

Parameters:

fragent_name

the name of the fragment in the database

const StringHashMap<String>& BALL::FragmentDB::getNamingStandard ( const String & std ) const

Return the naming standard given by std

Returns:: A StringHashMap that maps atom names to atom names

Exceptions:

StringHashMap<String>::IllegalKey

if std is not a valid naming standard

StringHashMap<NameMap>& BALL::FragmentDB::getNamingStandards ( )

Return a hash map containing all naming maps.

const Fragment* BALL::FragmentDB::getReferenceFragment ( const Fragment & fragment ) const

Return a reference fragment. This method returns a standard template of a given fragment or a NULL pointer if the fragment is not known. The first criterion is the fragment name. If there exist multiple variants of the fragment, the correct variant is chosen according to the properties set in fragment.

const Residue* BALL::FragmentDB::getResidue ( const String & fragment_name ) const

Return a residue.

Residue* BALL::FragmentDB::getResidueCopy ( const String & fragment_name ) const

Return a copy of a residue. If a fragment with name fragment_name exists in the fragment database, a copy is created and returned as a residue. Otherwise, a null pointer is returned. Take care to destruct the copy again to avoid memory leaks.

Returns:: a pointer to the copied fragment or 0

Parameters:

fragent_name

the name of the fragment in the database

list<String> BALL::FragmentDB::getVariantNames ( const String & name ) const

Return a list containing all variant names.

bool BALL::FragmentDB::has ( const String & fragment_name ) const

Checks whether a specified fragment is known to the fragment database.

void BALL::FragmentDB::init ( )

Initialization of the database.

Exceptions:

	Exception::FileNotFound	if the file is not found in the BALL_DATA_PATH
	Exception::NoFragmentNode	if the FragmentDB file did not contain any node entries
