class fesa::FieldStruct< T >

Field template class for struct fields.

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

slot	to put the value
val	value to put

Implements fesa::AbstractField.

template<typename T >

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

protectedvirtual

Returns: the struct attribute value of the pending buffer as a string

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

slot	The slot to get the field's value from

Returns: The field's value

Implements fesa::AbstractField.

template<typename T >

std::size_t fesa::FieldStruct< T >::getFieldValueAlignment ( ) const

protectedvirtual

Returns the alignment requirement of a FieldValue instantiated by this AbstractField object.

Implements fesa::AbstractField.

template<typename T >

std::size_t fesa::FieldStruct< T >::getFieldValueDataOffset ( ) const

protectedvirtual

Returns the offset from the beginning of the field value object to the data contained in the field value.

Implements fesa::AbstractField.

template<typename T >

std::size_t fesa::FieldStruct< T >::getFieldValueSize ( ) const

protectedvirtual

Returns the size (in bytes) of a field value instantiated by this AbstractField object. This includes the FieldValue object itself, and any additional space needed for data storage.

Implements fesa::AbstractField.

template<typename T >

void fesa::FieldStruct< T >::getValueToStore	(	int32_t	slot,
		std::string &	str
	)		const

protectedvirtual

Returns: the value of the pending buffer as a string

Implements fesa::AbstractField.

template<typename T >

void fesa::FieldStruct< T >::setFieldValueAddress	(	char *	pFV,
		bool	initFieldsFlag
	)

protectedvirtual

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

Parameters

pFV	pointer to a field value.

Implements fesa::AbstractField.

Reimplemented in fesa::FaultField< DataType >.
