Detailed Description

Data structure for the storage and lookup of MMFF94 angle-bending interaction parameters.

Constructor & Destructor Documentation

__init__()

None CDPL.ForceField.MMFF94AngleBendingParameterTable.__init__

(

MMFF94AngleBendingParameterTable

table

)

Initializes a copy of the MMFF94AngleBendingParameterTable instance table.

Parameters

table

The MMFF94AngleBendingParameterTable instance to copy.

Member Function Documentation

getObjectID()

int CDPL.ForceField.MMFF94AngleBendingParameterTable.getObjectID

(

)

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

Different Python MMFF94AngleBendingParameterTable 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 MMFF94AngleBendingParameterTable 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.MMFF94AngleBendingParameterTable.addEntry	(	int	angle_type_idx,
		int	term_atom1_type,
		int	ctr_atom_type,
		int	term_atom2_type,
		float	force_const,
		float	ref_angle
	)

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

Parameters

angle_type_idx	The MMFF94 angle type index.
term_atom1_type	The numeric MMFF94 atom type of the first terminal atom.
ctr_atom_type	The numeric MMFF94 atom type of the center atom.
term_atom2_type	The numeric MMFF94 atom type of the second terminal atom.
force_const	The angle-bending force constant.
ref_angle	The reference bond angle.

removeEntry()

bool CDPL.ForceField.MMFF94AngleBendingParameterTable.removeEntry	(	int	angle_type_idx,
		int	term_atom1_type,
		int	ctr_atom_type,
		int	term_atom2_type
	)

Removes the entry matching the specified query values.

Parameters

angle_type_idx	The MMFF94 angle type index.
term_atom1_type	The numeric MMFF94 atom type of the first terminal atom.
ctr_atom_type	The numeric MMFF94 atom type of the 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.MMFF94AngleBendingParameterTable.getEntry	(	int	angle_type_idx,
		int	term_atom1_type,
		int	ctr_atom_type,
		int	term_atom2_type
	)

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

Parameters

angle_type_idx	The MMFF94 angle type index.
term_atom1_type	The numeric MMFF94 atom type of the first terminal atom.
ctr_atom_type	The numeric MMFF94 atom type of the 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.MMFF94AngleBendingParameterTable.getNumEntries

(

)

Returns the number of entries in the table.

Returns

The entry count.

getEntries()

list CDPL.ForceField.MMFF94AngleBendingParameterTable.getEntries

(

)

Returns

load()

None CDPL.ForceField.MMFF94AngleBendingParameterTable.load

(

Base.IStream

is

)

Loads table entries from the input stream is.

Parameters

is	The input stream to read from.

assign()

MMFF94AngleBendingParameterTable CDPL.ForceField.MMFF94AngleBendingParameterTable.assign

(

MMFF94AngleBendingParameterTable

table

)

Replaces the current state of self with a copy of the state of the MMFF94AngleBendingParameterTable instance table.

Parameters

table

The MMFF94AngleBendingParameterTable instance to copy.

Returns

self

set()

None CDPL.ForceField.MMFF94AngleBendingParameterTable.set ( MMFF94AngleBendingParameterTable  table )

static

Replaces the process-wide default table by table.

Parameters

table

The new default table (a nullptr resets to the built-in default).

get()

MMFF94AngleBendingParameterTable CDPL.ForceField.MMFF94AngleBendingParameterTable.get ( )

static

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

Returns

A shared reference to the default table.
