◆ Table() [1/2]

template<typename T >
 Table< 7, T >::Table ( )
default

Default constructor. Set all dimensions to zero.

◆ Table() [2/2]

template<typename T >

Constructor. Pass down the given dimensions to the base class.

◆ operator[]() [1/2]

template<typename T >
 ::internal::TableBaseAccessors::Accessor<7, T, true, 6> Table< 7, T >::operator[] ( const size_type i ) const

Access operator. Generate an object that accesses the requested six- dimensional subobject of this seven-dimensional table. Range checks are performed.

This version of the function only allows read access.

◆ operator[]() [2/2]

template<typename T >
 ::internal::TableBaseAccessors::Accessor<7, T, false, 6> Table< 7, T >::operator[] ( const size_type i )

Access operator. Generate an object that accesses the requested six- dimensional subobject of this seven-dimensional table. Range checks are performed.

This version of the function allows read-write access.

◆ operator()() [1/6]

template<typename T >
 AlignedVector::const_reference Table< 7, T >::operator() ( const size_type i, const size_type j, const size_type k, const size_type l, const size_type m, const size_type n, const size_type o ) const

Direct access to one element of the table by specifying all indices at the same time. Range checks are performed.

This version of the function only allows read access.

◆ operator()() [2/6]

template<typename T >
 AlignedVector::reference Table< 7, T >::operator() ( const size_type i, const size_type j, const size_type k, const size_type l, const size_type m, const size_type n, const size_type o )

Direct access to one element of the table by specifying all indices at the same time. Range checks are performed.

This version of the function allows read-write access.

◆ operator()() [3/6]

template<typename T >
 AlignedVector::reference Table< 7, T >::operator() ( const TableIndices< 7 > & indices )

Make the corresponding operator () from the TableBase base class available also in this class.

◆ operator()() [4/6]

template<typename T >
 AlignedVector::const_reference Table< 7, T >::operator() ( const TableIndices< 7 > & indices ) const

Make the corresponding operator () from the TableBase base class available also in this class.

◆ operator==()

 bool TableBase< N, T >::operator== ( const TableBase< N, T > & T2 ) const
inherited

Test for equality of two tables.

◆ reset_values()

 void TableBase< N, T >::reset_values ( )
inherited

Set all entries to their default value (i.e. copy them over with default constructed objects). Do not change the size of the table, though.

◆ reinit()

 void TableBase< N, T >::reinit ( const TableIndices< N > & new_size, const bool omit_default_initialization = false )
inherited

Set the dimensions of this object to the sizes given in the first argument, and allocate the required memory for table entries to accommodate these sizes. If omit_default_initialization is set to false, all elements of the table are set to a default constructed object for the element type. Otherwise the memory is left in an uninitialized or otherwise undefined state.

◆ size() [1/2]

 size_type TableBase< N, T >::size ( const unsigned int i ) const
inherited

Size of the table in direction i.

◆ size() [2/2]

 const TableIndices& TableBase< N, T >::size ( ) const
inherited

Return the sizes of this object in each direction.

◆ n_elements()

 size_type TableBase< N, T >::n_elements ( ) const
inherited

Return the number of elements stored in this object, which is the product of the extensions in each dimension.

◆ empty()

 bool TableBase< N, T >::empty ( ) const
inherited

Return whether the object is empty, i.e. one of the directions is zero. This is equivalent to n_elements()==0.

◆ fill() [1/2]

 void TableBase< N, T >::fill ( InputIterator entries, const bool C_style_indexing = true )
inherited

Fill this table (which is assumed to already have the correct size) from a source given by dereferencing the given forward iterator (which could, for example, be a pointer to the first element of an array, or an inserting std::istream_iterator). The second argument denotes whether the elements pointed to are arranged in a way that corresponds to the last index running fastest or slowest. The default is to use C-style indexing where the last index runs fastest (as opposed to Fortran-style where the first index runs fastest when traversing multidimensional arrays. For example, if you try to fill an object of type Table<2,T>, then calling this function with the default value for the second argument will result in the equivalent of doing

for (unsigned int i=0; i<t.size(0); ++i)
for (unsigned int j=0; j<t.size(1); ++j)
t[i][j] = *entries++;

On the other hand, if the second argument to this function is false, then this would result in code of the following form:

for (unsigned int j=0; j<t.size(1); ++j)
for (unsigned int i=0; i<t.size(0); ++i)
t[i][j] = *entries++;

Note the switched order in which we fill the table elements by traversing the given set of iterators.

Parameters
 entries An iterator to a set of elements from which to initialize this table. It is assumed that iterator can be incremented and dereferenced a sufficient number of times to fill this table. C_style_indexing If true, run over elements of the table with the last index changing fastest as we dereference subsequent elements of the input range. If false, change the first index fastest.

◆ fill() [2/2]

 void TableBase< N, T >::fill ( const T & value )
inherited

Fill all table entries with the same value.

◆ operator()() [5/6]

 AlignedVector::reference TableBase< N, T >::operator() ( const TableIndices< N > & indices )
inherited

Return a read-write reference to the indicated element.

◆ operator()() [6/6]

 AlignedVector::const_reference TableBase< N, T >::operator() ( const TableIndices< N > & indices ) const
inherited

Return the value of the indicated element as a read-only reference.

We return the requested value as a constant reference rather than by value since this object may hold data types that may be large, and we don't know here whether copying is expensive or not.

◆ swap()

 void TableBase< N, T >::swap ( TableBase< N, T > & v )
inherited

Swap the contents of this table and the other table v. One could do this operation with a temporary variable and copying over the data elements, but this function is significantly more efficient since it only swaps the pointers to the data of the two vectors and therefore does not need to allocate temporary storage and move data around.

This function is analogous to the swap function of all C++ standard containers. Also, there is a global function swap(u,v) that simply calls u.swap(v), again in analogy to standard functions.

◆ memory_consumption()

 std::size_t TableBase< N, T >::memory_consumption ( ) const
inherited

Determine an estimate for the memory consumption (in bytes) of this object.

◆ serialize()

 void TableBase< N, T >::serialize ( Archive & ar, const unsigned int version )
inherited

Write or read the data of this object to or from a stream for the purpose of serialization using the BOOST serialization library.

◆ position()

 size_type TableBase< N, T >::position ( const TableIndices< N > & indices ) const
protectedinherited

Return the position of the indicated element within the array of elements stored one after the other. This function does no index checking.

◆ el() [1/2]

 AlignedVector::reference TableBase< N, T >::el ( const TableIndices< N > & indices )
protectedinherited

Return a read-write reference to the indicated element.

This function does no bounds checking and is only to be used internally and in functions already checked.

◆ el() [2/2]

 AlignedVector::const_reference TableBase< N, T >::el ( const TableIndices< N > & indices ) const
protectedinherited

Return the value of the indicated element as a read-only reference.

This function does no bounds checking and is only to be used internally and in functions already checked.

We return the requested value as a constant reference rather than by value since this object may hold data types that may be large, and we don't know here whether copying is expensive or not.

◆ subscribe()

 void Subscriptor::subscribe ( std::atomic< bool > *const validity, const std::string & identifier = "" ) const
inherited

Subscribes a user of the object by storing the pointer validity. The subscriber may be identified by text supplied as identifier.

Definition at line 136 of file subscriptor.cc.

◆ unsubscribe()

 void Subscriptor::unsubscribe ( std::atomic< bool > *const validity, const std::string & identifier = "" ) const
inherited

Unsubscribes a user from the object.

Note
The identifier and the validity pointer must be the same as the one supplied to subscribe().

Definition at line 156 of file subscriptor.cc.

◆ n_subscriptions()

 unsigned int Subscriptor::n_subscriptions ( ) const
inlineinherited

Return the present number of subscriptions to this object. This allows to use this class for reference counted lifetime determination where the last one to unsubscribe also deletes the object.

Definition at line 301 of file subscriptor.h.

◆ list_subscribers() [1/2]

template<typename StreamType >
 void Subscriptor::list_subscribers ( StreamType & stream ) const
inlineinherited

List the subscribers to the input stream.

Definition at line 318 of file subscriptor.h.

◆ list_subscribers() [2/2]

 void Subscriptor::list_subscribers ( ) const
inherited

List the subscribers to deallog.

Definition at line 204 of file subscriptor.cc.

◆ values

 AlignedVector TableBase< N, T >::values
protectedinherited

Component-array.

Definition at line 662 of file table.h.

◆ table_size

 TableIndices TableBase< N, T >::table_size
protectedinherited

Size in each direction of the table.

Definition at line 667 of file table.h.
