Constructor & Destructor Documentation

◆ init()

None CDPL.ForceField.MMFF94TorsionParameterTable.__init__ ( MMFF94TorsionParameterTable table )

Initializes a copy of the MMFF94TorsionParameterTable instance table.

Parameters

table The MMFF94TorsionParameterTable instance to copy.

Member Function Documentation

◆ getObjectID()

int CDPL.ForceField.MMFF94TorsionParameterTable.getObjectID ( )

Returns the numeric identifier (ID) of the wrapped C++ class instance.

Different Python MMFF94TorsionParameterTable instances may reference the same underlying C++ class instance. The commonly used Python expression a is not b thus cannot tell reliably whether the two MMFF94TorsionParameterTable instances a and b reference different C++ objects. The numeric identifier returned by this method allows to correctly implement such an identity test via the simple expression a.getObjectID() != b.getObjectID().

Returns: The numeric ID of the internally referenced C++ class instance.

◆ addEntry()

None CDPL.ForceField.MMFF94TorsionParameterTable.addEntry	(	int	tor_type_idx,
		int	term_atom1_type,
		int	ctr_atom1_type,
		int	ctr_atom2_type,
		int	term_atom2_type,
		float	tor_param1,
		float	tor_param2,
		float	tor_param3
	)

Adds a new (or overwrites an existing) entry for the given query and parameter values.

Parameters

tor_type_idx	The MMFF94 torsion type index.
term_atom1_type	The numeric MMFF94 atom type of the first terminal atom.
ctr_atom1_type	The numeric MMFF94 atom type of the first center atom.
ctr_atom2_type	The numeric MMFF94 atom type of the second center atom.
term_atom2_type	The numeric MMFF94 atom type of the second terminal atom.
tor_param1	The torsion-energy parameter `V1`.
tor_param2	The torsion-energy parameter `V2`.
tor_param3	The torsion-energy parameter `V3`.

◆ removeEntry()

bool CDPL.ForceField.MMFF94TorsionParameterTable.removeEntry	(	int	tor_type_idx,
		int	term_atom1_type,
		int	ctr_atom1_type,
		int	ctr_atom2_type,
		int	term_atom2_type
	)

Removes the entry matching the specified query values.

Parameters

tor_type_idx	The MMFF94 torsion type index.
term_atom1_type	The numeric MMFF94 atom type of the first terminal atom.
ctr_atom1_type	The numeric MMFF94 atom type of the first center atom.
ctr_atom2_type	The numeric MMFF94 atom type of the second center atom.
term_atom2_type	The numeric MMFF94 atom type of the second terminal atom.

Returns: True if a matching entry was removed, and False if no such entry existed.

◆ getEntry()

Entry CDPL.ForceField.MMFF94TorsionParameterTable.getEntry	(	int	tor_type_idx,
		int	term_atom1_type,
		int	ctr_atom1_type,
		int	ctr_atom2_type,
		int	term_atom2_type
	)

Returns a reference to the entry matching the specified query values.

Parameters

tor_type_idx	The MMFF94 torsion type index.
term_atom1_type	The numeric MMFF94 atom type of the first terminal atom.
ctr_atom1_type	The numeric MMFF94 atom type of the first center atom.
ctr_atom2_type	The numeric MMFF94 atom type of the second center atom.
term_atom2_type	The numeric MMFF94 atom type of the second terminal atom.

Returns: A reference to the matching entry or to an uninitialized entry if no matching entry exists.

◆ getNumEntries()

int CDPL.ForceField.MMFF94TorsionParameterTable.getNumEntries ( )

Returns the number of entries in the table.

Returns: The entry count.

◆ getEntries()

list CDPL.ForceField.MMFF94TorsionParameterTable.getEntries ( )

Returns

◆ load()

None CDPL.ForceField.MMFF94TorsionParameterTable.load ( Base.IStream is )

Loads table entries from the input stream is.

Parameters

is	The input stream to read from.

◆ loadDefaults()

None CDPL.ForceField.MMFF94TorsionParameterTable.loadDefaults ( int param_set )

Loads the built-in default torsion parameter entries for the specified MMFF94 parameter set.

Parameters

param_set The parameter set identifier (see namespace ForceField.MMFF94ParameterSet) selecting which built-in defaults to load.

◆ assign()

MMFF94TorsionParameterTable CDPL.ForceField.MMFF94TorsionParameterTable.assign ( MMFF94TorsionParameterTable table )

Replaces the current state of self with a copy of the state of the MMFF94TorsionParameterTable instance table.

Parameters

table The MMFF94TorsionParameterTable instance to copy.

Returns: self

◆ set()

None CDPL.ForceField.MMFF94TorsionParameterTable.set	(	MMFF94TorsionParameterTable	table,
		int	param_set
	)

static

Replaces the process-wide default table for param_set by table.

Parameters

table	The new default table (`None` resets to the built-in default).
param_set	The parameter set identifier (see namespace ForceField.MMFF94ParameterSet) selecting which default slot to replace.

◆ get()

MMFF94TorsionParameterTable CDPL.ForceField.MMFF94TorsionParameterTable.get ( int param_set )

static

Returns the process-wide default table for param_set (lazily initialized on first call).

Parameters

param_set The parameter set identifier (see namespace ForceField.MMFF94ParameterSet) selecting which default slot to return.

Returns: A shared reference to the selected default table.
