Detailed Description

template<class TPtr, class UP>
class pcl::IndirectUnaryPredicate< TPtr, UP >

The UP template argument represents a unary predicate type of the form:

bool (*UP)( T )

The TPtr template argument represents a pointer to UP's argument type. TPtr is also the argument type of IndirectUnaryPredicate::operator ()().

IndirectUnaryPredicate can be used as UP, but acting on pointers to objects of type T.

pcl::IndirectUnaryPredicate< TPtr, UP >::IndirectUnaryPredicate ( const IndirectUnaryPredicate< TPtr, UP > &  )

default

Copy constructor.

Member Function Documentation

operator()()

template<class TPtr , class UP >

bool pcl::IndirectUnaryPredicate< TPtr, UP >::operator() ( TPtr  ptr ) const

inline

Function call operator. Applies the wrapped unary predicate to *ptr and returns its resulting value.

If ptr is nullptr, the predicate is not invoked and false is returned.
