Detailed Description

This wraps a (shared) pointer to an underlying structure.

The typical use-case is when a PseusoJet needs to share its structure with another PseudoJet but also include extra information in its structure. For the memory management to be handled properly, it should hold a shared pointer to the shared structure. This is what this class ensures. Deriving a structure from this class would then allow for the implementation of the extra features.

virtual bool fastjet::WrappedStructure::has_valid_cluster_sequence ( ) const

inlinevirtual

returns true if this PseudoJet has an associated and still valid ClusterSequence.

Reimplemented from fastjet::PseudoJetStructureBase.

Definition at line 90 of file WrappedStructure.hh.

virtual bool fastjet::WrappedStructure::has_partner	(	const PseudoJet &	reference,
		PseudoJet &	partner
	)		const

inlinevirtual

check if it has been recombined with another PseudoJet in which case, return its partner through the argument.

Otherwise, 'partner' is set to 0.

By default, throws an Error

Reimplemented from fastjet::PseudoJetStructureBase.

Definition at line 122 of file WrappedStructure.hh.

virtual bool fastjet::WrappedStructure::has_child	(	const PseudoJet &	reference,
		PseudoJet &	child
	)		const

inlinevirtual

check if it has been recombined with another PseudoJet in which case, return its child through the argument.

Otherwise, 'child' is set to 0.

By default, throws an Error

Reimplemented from fastjet::PseudoJetStructureBase.

Definition at line 131 of file WrappedStructure.hh.

virtual bool fastjet::WrappedStructure::has_parents	(	const PseudoJet &	reference,
		PseudoJet &	parent1,
		PseudoJet &	parent2
	)		const

inlinevirtual

check if it is the product of a recombination, in which case return the 2 parents through the 'parent1' and 'parent2' arguments.

Otherwise, set these to 0.

By default, throws an Error

Reimplemented from fastjet::PseudoJetStructureBase.

Definition at line 140 of file WrappedStructure.hh.

virtual bool fastjet::WrappedStructure::object_in_jet	(	const PseudoJet &	reference,
		const PseudoJet &	jet
	)		const

inlinevirtual

check if the reference PseudoJet is contained the second one passed as argument.

By default, throws an Error

Reimplemented from fastjet::PseudoJetStructureBase.

Definition at line 148 of file WrappedStructure.hh.

virtual bool fastjet::WrappedStructure::has_constituents ( ) const

inlinevirtual

false by default

Reimplemented from fastjet::PseudoJetStructureBase.

virtual std::vector<PseudoJet> fastjet::WrappedStructure::constituents ( const PseudoJet & reference ) const

virtual std::vector<PseudoJet> fastjet::WrappedStructure::exclusive_subjets	(	const PseudoJet &	reference,

inlinevirtual

return a vector of all subjets of the current jet (in the sense of the exclusive algorithm) that would be obtained when running the algorithm with the given dcut.

Time taken is O(m ln m), where m is the number of subjets that are found. If m gets to be of order of the total number of constituents in the jet, this could be substantially slower than just getting that list of constituents.

By default, throws an Error
