Detailed Description

Accessor to input data conforming to declared Array.

There are two possible ways how to retrieve data from Array accessor. First, you can use generic copy_to function to copy the data into a given container. Second, you can get an Iterator<Type> and iterate through the Array. Unfortunately, you have to provide Type to the begin() method so this implementation is not fully compliant with standard library. The reason is that in order to speed up compilation of many classes using input accessors we wouldn't have Input::Array a class template that it can be compiled only once. By this reason one can not use BOOST_FOREACH to iterate over Input::Array. TODO: Make Input::Array<Type> wrapper which is compliant with standard library.

In either case correspondence between resulting type (i.e. type of elements of the container or type of the Iterator) and the type of the data in the Array is checked only once.

Example of usage:

Input::Array decay_array = in_rec.val<Input::Array>("decays");       // get accessor to an array stored under key 'decays'
int size = decay_array.size();                                       // get size of the actual arrya in the input (possibly for allocation)
for(Input::Iterator<Input::Record> it = decay_array.begin<Input::Record>()   // pass through the array, that is array of records
         ; it != dacay_array.end(); ++it) {
    Input::Iterator<double> it_hl = it->find<double>("half_life");   // check existence of an optional key
    if (it_hl) {
         double hl = *it_hl;
    } else {
         // use some other value, or turn-off the decay
    }
    Input::Array products = it->val<Input::Array>("products");       // read an obligatory key, theat conatins an array
    // ... process the array 'products'
}

Constructor & Destructor Documentation

Input::Array::Array ( )

Default constructor, empty accessor.

Constructor uses empty Address which causes error in program, Address has to be filled.

Definition at line 279 of file accessors.cc.

Input::Array::Array ( const Array & ar )

Copy constructor.

Definition at line 284 of file accessors.cc.

Input::Array::Array	(	const Address &	address,
		const Type::Array	type
	)

Constructs the accessor providing pointer store to storage node with list of data of the record and type specification of the record given by parameter type.

Definition at line 289 of file accessors.cc.

Member Function Documentation

string Input::Array::address_string ( ) const

Get address as string.

Definition at line 304 of file accessors.cc.

Here is the caller graph for this function:

template<class ValueType >

Iterator< ValueType > Input::Array::begin ( ) const

inline

Returns iterator to the first element of input array. The template parameter is C++ type you want to read from the array. Only types supported by Input::Interface::Iterator can be used.

Definition at line 127 of file accessors_impl.hh.

Here is the caller graph for this function:

template<class Container >

void Input::Array::copy_to ( Container & out ) const

Method to fill the given container out with data in the input Array. The container has to have methods clear and push_back. The C++ type of the values in the container has to be supported by Iterator<T>.

Definition at line 152 of file accessors_impl.hh.

Here is the caller graph for this function:

Input::EI_Address Input::Array::ei_address ( ) const

Returns address error info.

Definition at line 297 of file accessors.cc.

Here is the caller graph for this function:

IteratorBase Input::Array::end ( ) const

inline

Returns end iterator common to all iterators inner types.

Definition at line 139 of file accessors_impl.hh.

Here is the caller graph for this function:

bool Input::Array::is_empty ( ) const

inline

Returns true if the accessor is empty (after default constructor). TODO: have something similar for other accessors.

Definition at line 610 of file accessors.hh.

unsigned int Input::Array::size ( ) const

inline

Actual size of the input array.

Definition at line 145 of file accessors_impl.hh.

Here is the caller graph for this function:
