getSpecification
Gets the specification attribute of the MannholdLogPDescriptor object.- Specified by:
getSpecification
in interfaceIDescriptor
- Returns:
- The specification value
-
setParameters
ThisIDescriptor
does not have any parameters. If it had, this would have been the method to set them.- Specified by:
setParameters
in interfaceIDescriptor
- Parameters:
params
- The new parameter value- Throws:
CDKException
- Exception throw when invalid parameter values are passed- See Also:
-
getParameters
Gets the parameters attribute of the MannholdLogPDescriptor object.- Specified by:
getParameters
in interfaceIDescriptor
- Returns:
- A zero-length Object array.

getDescriptorNames
Description copied from interface:IDescriptor
Returns an array of names for each descriptor value calculated. Many descriptors return multiple values. In general it is useful for the descriptor to indicate the names for each value. In many cases, these names can be as simple as X1, X2, ..., XN where X is a prefix and 1, 2, ..., N are the indices. On the other hand it is also possible to return other arbitrary names, which should be documented in the Javadocs for the descriptor (e.g., the CPSA descriptor). Note that by default if a descriptor returns a single value (such asALOGPDescriptor
the return array will have a single element- Specified by:
getDescriptorNames
in interfaceIDescriptor
- Returns:
- An array of descriptor names, equal in length to the number of descriptor calculated..
-
calculate
Calculates the Mannhold LogP for an atom container.- Specified by:
calculate
in interfaceIMolecularDescriptor
- Parameters:
atomContainer
-IAtomContainer
to calculate the descriptor value for.- Returns:
- A descriptor value wrapping a
DoubleResult
.
-
getDescriptorResultType
Returns a type of return value calculated by this descriptor.- Specified by:
getDescriptorResultType
in interfaceIMolecularDescriptor
- Returns:
- returns a
DoubleResult
.
-
getParameterNames
Gets the parameterNames attribute for this descriptor.- Specified by:
getParameterNames
in interfaceIDescriptor
- Returns:
- A zero-length String array.
-
getParameterType
Gets the parameterType attribute for a given parameter name. It always returns null, as this descriptor does not have any parameters.- Specified by:
getParameterType
in interfaceIDescriptor
- Parameters:
name
- Name of the parameter for which the type is requested.- Returns:
- The parameterType of the given parameter.
-
initialise
Default implementation of initialise allows optional override.- Specified by:
initialise
in interfaceIDescriptor
- Parameters:
builder
- chem object build
