Function Documentation

template<class T >

T * Gecode::Space::alloc ( long unsigned int n ) [inline, inherited]

Allocate block of n objects of type T from space heap.

Note that this function implements C++ semantics: the default constructor of T is run for all n objects.

Definition at line 1941 of file core.hpp.

template<class T >

T * Gecode::Space::alloc ( long int n ) [inline, inherited]

Allocate block of n objects of type T from space heap.

Note that this function implements C++ semantics: the default constructor of T is run for all n objects.

Definition at line 1949 of file core.hpp.

template<class T >

T * Gecode::Space::alloc ( unsigned int n ) [inline, inherited]

Allocate block of n objects of type T from space heap.

Note that this function implements C++ semantics: the default constructor of T is run for all n objects.

Definition at line 1955 of file core.hpp.

template<class T >

T * Gecode::Space::alloc ( int n ) [inline, inherited]

Allocate block of n objects of type T from space heap.

Note that this function implements C++ semantics: the default constructor of T is run for all n objects.

Definition at line 1960 of file core.hpp.

template<class T >

void Gecode::Space::free	(	T *	b,
		long unsigned int	n
	)			`[inline, inherited]`

Delete n objects allocated from space heap starting at b.

Note that this function implements C++ semantics: the destructor of T is run for all n objects.

Note that the memory is not freed, it is just scheduled for latter reusal.

Definition at line 1967 of file core.hpp.

template<class T >

void Gecode::Space::free	(	T *	b,
		long int	n
	)			`[inline, inherited]`

Delete n objects allocated from space heap starting at b.

Note that this function implements C++ semantics: the destructor of T is run for all n objects.

Note that the memory is not freed, it is just scheduled for latter reusal.

Definition at line 1974 of file core.hpp.

template<class T >

void Gecode::Space::free	(	T *	b,
		unsigned int	n
	)			`[inline, inherited]`

Delete n objects allocated from space heap starting at b.

Note that this function implements C++ semantics: the destructor of T is run for all n objects.

Note that the memory is not freed, it is just scheduled for latter reusal.

Definition at line 1980 of file core.hpp.

template<class T >

void Gecode::Space::free	(	T *	b,
		int	n
	)			`[inline, inherited]`

Delete n objects allocated from space heap starting at b.

Note that this function implements C++ semantics: the destructor of T is run for all n objects.

Note that the memory is not freed, it is just scheduled for latter reusal.

Definition at line 1985 of file core.hpp.

template<class T >

T * Gecode::Space::realloc	(	T *	b,
		long unsigned int	n,
		long unsigned int	m
	)			`[inline, inherited]`

Reallocate block of n objects starting at b to m objects of type T from the space heap.

Note that this function implements C++ semantics: the copy constructor of T is run for all $\min(n,m)$ objects, the default constructor of T is run for all remaining $\max(n,m)-\min(n,m)$ objects, and the destrucor of T is run for all n objects in b.
