Constructor & Destructor Documentation

template<typename T >
fesa::FieldArray< T >::FieldArray ( const FieldConfig fieldConfig,
DataStore pDataStore,
std::size_t  size 
)

Constructor.

Parameters
nameof the field, field category, multiplexing criterion, pointer to DataStore
sizeof the array

Member Function Documentation

template<typename T>
void fesa::FieldArray< T >::checkIndexBounds ( const FieldValueArray< T > &  fieldValue,
std::size_t  index 
) const
protected

Ensures that index is within the current size of the given fieldValue.

Exceptions
FesaExceptionif index is out of bounds.
template<typename T >
void fesa::FieldArray< T >::checkMaxDimension ( std::size_t  size) const
protected

this method checks whether the size passed by parameter is within the max size of the array. If it is not, the method throws a FesaException

Exceptions
FesaException
template<typename T >
void fesa::FieldArray< T >::copyValue ( uint32_t  slot,
const std::string &  str 
)
protectedvirtual

this method puts in the slot the value passed by parameter in the corresponding format

Parameters
slotto put the value
valvalue to put

Implements fesa::AbstractField.

Reimplemented in fesa::FieldFunctionList.

template<typename T>
const T & fesa::FieldArray< T >::getCellRef ( const FieldValueArray< T > &  fieldValue,
std::size_t  index 
) const
protected

Returns a reference to the fieldValue's cell at the given index.

template<typename T >
FieldValueArray< T > * fesa::FieldArray< T >::getFieldValue ( int32_t  slot)
protectedvirtual

Get the field's value for a given slot.

Parameters
slotThe slot to get the field's value from
Returns
The field's value

Implements fesa::AbstractField.

template<typename T >
std::size_t fesa::FieldArray< T >::getFieldValueSize ( ) const
protectedvirtual

Method to get the size of the field-value object. The template of the field-value class depends on the field type.

Returns
the size in bytes of the field value object.

Implements fesa::AbstractField.

template<typename T >
std::size_t fesa::FieldArray< T >::getMaxSize ( ) const

retrieve the size of the array

Returns
size of the array
template<typename T >
void fesa::FieldArray< T >::getValueToStore ( int32_t  slot,
std::string &  str 
) const
protectedvirtual
Returns
the value of the pending buffer as a string

Implements fesa::AbstractField.

Reimplemented in fesa::FieldFunctionList.

template<typename T >
void fesa::FieldArray< T >::initializeDimensions ( const boost::shared_ptr< FieldElement > &  fieldElement)
protectedvirtual

used to initialize dimensions of the field from the instance document

Parameters
fieldElementthat contains the values for the field

Reimplemented from fesa::AbstractField.

Reimplemented in fesa::FieldFunctionList.

template<typename T>
void fesa::FieldArray< T >::setCellValue ( FieldValueArray< T > &  fieldValue,
const T &  val,
std::size_t  index 
)
protected

Copies val to the fieldValue's cell at the given index.

template<typename T>
void fesa::FieldArray< T >::setFieldValue ( FieldValueArray< T > &  fieldValue,
const T *  val,
std::size_t  size 
)
protected

Copies the given values to the fieldValue.

Parameters
fieldValuethe destination fieldValue
valthe values to copy
sizenumber of values to copy
template<typename T>
template<typename RandomAccessIterator >
void fesa::FieldArray< T >::setFieldValue ( FieldValueArray< T > &  fieldValue,
RandomAccessIterator  first,
RandomAccessIterator  last 
)
protected

Copies the given values to the fieldValue, from first (included) to last (excluded). Given iterators must support random access.

Parameters
fieldValuethe destination fieldValue
firstIterator pointing to the first value to copy (included)
lastIterator pointing to the last value to copy (excluded)
template<typename T >
void fesa::FieldArray< T >::setFieldValueAddress ( char *  pFV,

protectedvirtual

Maps an address in shared memory or on the heap to the field value member of the field class.

Parameters
pFVpointer to a field value.

Implements fesa::AbstractField.
