#define IMP_SHOWABLE_INLINE(Name, how_to_show)
Declare the methods needed by an object that can be printed.
float get_rnormfac() const
Get the Gaussian normalization factor.
Calculates and stores Gaussian kernel parameters.
Exception definitions and assertions.
A more IMP-like version of the std::vector.
#define IMP_INTERNAL_CHECK(expr, message)
An assertion to check for internal errors in IMP. An IMP::ErrorException will be thrown.
#define IMP_VALUES(Name, PluralName)
Define the type for storing sets of values.
float get_rkdist() const
