Function Documentation

◆ operator<<() [1/10]

template<class Type , class Key >
std::ostream& abacus::operator<< ( std::ostream &  out,
const AbaBHeap< Type, Key > &  heap 
)

Writes the elements of the heap together with their keys on an output stream.

Parameters
outThe output stream.
heapThe heap being output.
Returns
A reference to the output stream.

◆ operator<<() [2/10]

template<class KeyType , class ItemType >
std::ostream& abacus::operator<< ( std::ostream &  out,
const AbaHash< KeyType, ItemType > &  hash 
)

Writes row by row all elements stored in the list associated with a slot on an output stream.

The output of an empty slot is suppressed.

Parameters
outThe output stream.
hashThe hash table being output.
Returns
A reference to the output stream.

◆ operator<<() [3/10]

template<class KeyType , class ItemType >
std::ostream& abacus::operator<< ( std::ostream &  out,
const AbaHashItem< KeyType, ItemType > &  rhs 
)
Returns
A reference to the output stream.

◆ operator<<() [4/10]

template<class Type >
std::ostream& abacus::operator<< ( std::ostream &  out,
const AbaRing< Type > &  ring 
)

Writes the elements of the ring to an output stream starting with the oldest element in the ring.

Parameters
outThe output stream.
ringThe ring being output.
Returns
A reference to the output stream.

◆ operator<<() [5/10]

template<class BaseType , class CoType >
std::ostream& abacus::operator<< ( std::ostream &  out,
const Active< BaseType, CoType > &  rhs 
)

The output operator writes all active constraints and variables to an output stream.

If an associated pool slot is void, or the item is newer than the one we refer to, then "void" is written.

Parameters
outThe output stream.
rhsThe active set being output.
Returns
A reference to the output stream.

◆ operator<<() [6/10]

std::ostream& abacus::operator<< ( std::ostream &  out,
const BoundBranchRule rhs 
)
inline

Writes the branching variable together with its lower and upper bound to an output stream.

Parameters
outThe output stream.
rhsThe branch rule being output.
Returns
A reference to the output stream.

Definition at line 133 of file boundbranchrule.h.

◆ operator<<() [7/10]

std::ostream& abacus::operator<< ( std::ostream &  out,
const ColVar rhs 
)
inline

The output operator writes the column representing the variable to an output stream.

Parameters
outThe output stream.
rhsThe variable being output.
Returns
A reference to the output stream.

Definition at line 177 of file colvar.h.

◆ operator<<() [8/10]

template<class BaseType , class CoType >
std::ostream& abacus::operator<< ( std::ostream &  out,
const LpSolution< BaseType, CoType > &  rhs 
)
Parameters
outThe output stream.
rhsThe lpsolution being output.
Returns
A reference to the output stream.

◆ operator<<() [9/10]

template<class BaseType , class CoType >
std::ostream& abacus::operator<< ( std::ostream &  out,
const PoolSlotRef< BaseType, CoType > &  slot 
)

The output operator writes the constraint/variable stored in the referenced slot to an output stream.

Parameters
outThe output stream.
slotThe reference to a pool slot being output.
Returns
A reference to the output stream.

◆ operator<<() [10/10]

template<class BaseType , class CoType >
std::ostream& abacus::operator<< ( std::ostream &  out,
const StandardPool< BaseType, CoType > &  rhs 
)

The output operator calls the output operator of each item of a non-void pool slot.

Parameters
outThe output stream.
rhsThe pool being output.
Returns
A reference to the output stream.
