Member Function Documentation

template<typename T >
void fesa::FieldStruct< T >::copyValue ( uint32_t  slot,
const std::string &  val 
)
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.

template<typename T >
void fesa::FieldStruct< T >::getAttributeValueToStore ( int32_t  slot,
const std::string &  attribute,
std::string &  str 
)
protectedvirtual

Reimplemented from fesa::AbstractField.

template<typename T >
FieldValue< T > * fesa::FieldStruct< T >::getFieldValue ( int32_t  slot)
inlineprotectedvirtual

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 >

Parameters
pFVpointer to a field value.

Implements fesa::AbstractField.

Reimplemented in fesa::FaultField< DataType >.
