ClocksDifference

public ClocksDifference(ClockModel clock1,
 ClockModel clock2)

Simple constructor.

The combined clock is clock1 - clock2

Parameters:

clock1 - first underlying clock

clock2 - second underlying clock

Method Details

combine

protected ClockOffset combine(ClockOffset offset1,
 ClockOffset offset2)

Description copied from class: AbstractCombinedClocksPair

Combine two offsets.

Specified by:

combine in class AbstractCombinedClocksPair

Parameters:

offset1 - first offset

offset2 - second offset

Returns:

combined offset

combine

protected <T extends CalculusFieldElement<T>>
FieldClockOffset<T> combine(FieldClockOffset<T> offset1,
 FieldClockOffset<T> offset2)

Combine two offsets.

Specified by:

combine in class AbstractCombinedClocksPair

Type Parameters:

T - type of the field elements

Parameters:

offset1 - first offset

offset2 - second offset

Returns:

combined offset

getFieldModel

public FieldClockModel<Gradient> getFieldModel(int freeParameters,
 Map<String,Integer> indices,
 AbsoluteDate date)

Description copied from interface: ClockModel

Convert to field model.

Parameters:

freeParameters - total number of free parameters in the gradient

indices - indices of the differentiation parameters in derivatives computations, must be span name and not driver name

date - date at which model must be valid

Returns:

converted clock model
