PharmacophoreQueryAngleBond

public PharmacophoreQueryAngleBond(PharmacophoreQueryAtom atom1,
                                   PharmacophoreQueryAtom atom2,
                                   PharmacophoreQueryAtom atom3,
                                   double lower,
                                   double upper)

Create a query angle constraint between three query groups.

Note that the angle is only considered upto 2 decimal places.

Parameters:

atom1 - The first pharmacophore group

atom2 - The second pharmacophore group

atom3 - The third pharmacophore group

lower - The lower bound of the angle between the three groups

upper - The upper bound of the angle between the three groups

PharmacophoreQueryAngleBond

public PharmacophoreQueryAngleBond(PharmacophoreQueryAtom atom1,
                                   PharmacophoreQueryAtom atom2,
                                   PharmacophoreQueryAtom atom3,
                                   double angle)

Create a query angle constraint between three query groups.

This constructor allows you to define a query angle constraint such that the angle between the three query groups is exact (i.e., not a range).

Note that the angle is only considered upto 2 decimal places.

Parameters:

atom1 - The first pharmacophore group

atom2 - The second pharmacophore group

atom3 - The third pharmacophore group

angle - The exact angle between the two groups

Method Detail

matches

@TestMethod(value="testMatches")
public boolean matches(IBond bond)

Checks whether the query angle constraint matches a target distance.

This method checks whether a query constraint is satisfied by an observed angle (represented by a PharmacophoreAngleBond in the target molecule. Note that angles are compared upto 2 decimal places.

Specified by:

matches in interface IQueryBond

Parameters:

bond - The angle relationship in a target molecule

Returns:

true if the target angle lies within the range of the query constraint

getUpper

@TestMethod(value="testUpper")
public double getUpper()

getLower

@TestMethod(value="testLower")
public double getLower()

toString

@TestMethod(value="testToString")
public String toString()

String representation of an angle constraint.

Specified by:

toString in interface IChemObject

Overrides:

toString in class Bond

Returns:

String representation of and angle constraint
