Detailed Description

Function Documentation

◆ SelectorIdentity()

Selector fastjet::SelectorIdentity ( )

Definition at line 259 of file Selector.cc.

◆ operator!()

Selector fastjet::operator! ( const Selector & s )

logical not applied on a selector

This will keep objects that do not pass the 's' selector

Definition at line 333 of file Selector.cc.

◆ operator||()

Selector fastjet::operator\|\|	(	const Selector &	s1,
		const Selector &	s2
	)

logical or between two selectors

this will keep the objects that are selected by s1 or s2

Definition at line 519 of file Selector.cc.

◆ operator&&()

Selector fastjet::operator&&	(	const Selector &	s1,
		const Selector &	s2
	)

logical and between two selectors

this will keep the objects that are selected by both s1 and s2

watch out: for both s1 and s2, the selection is applied on the original list of objects. For successive applications of two selectors (convolution/multiplication) see the operator *

Definition at line 443 of file Selector.cc.

◆ operator*()

Selector fastjet::operator*	(	const Selector &	s1,
		const Selector &	s2
	)

successive application of 2 selectors

Apply the selector s2, then the selector s1.

watch out: the operator * acts like an operator product i.e. does not commute. The order of its arguments is therefore important. Whenever they commute (in particluar, when they apply jet by jet), this would have the same effect as the logical &&.
