Serialization facilities
Serialization/deserialization is performed with record definition in case of own memory buffer is used or without it in case of link to alien memory buffer location. Serial format (included record definition): +0 Number of domains (4 byte integer) = N +4 Domain definitions (40 bytes for each domain) +4+40*N Extended information size (4 byte integer) = E +8+40*N Extended information +8+40*N+E Record data in order of domains Serial format (without record definition): +0 Extended information size (4 byte integer) = E +4 Extended information +4+E Record data in order of domains

Constructor & Destructor Documentation

RecItem::RecItem

(

const RecDef &

rdef

)

Create new record with empty contents (see AnyValue::empty_value() for each cell initialization)

RecItem::RecItem

(

const RecItem &

r

)

Create the copy of some record item

RecItem::RecItem

(

InputStream &

ist

)

Create record item from the input stream

RecItem::RecItem	(	RecDef *	prdef,
		void *	recdata
	)

Create record object which is attached to some record definition and some data location. BE CAREFUL!!!

virtual RecItem::~RecItem ( )

virtual

Destroy the object

Member Function Documentation

virtual void RecItem::add_domain ( const DomainDef &  dmn )

virtual

Add one more domain to record item. New cell became empty (initialized by default).

Reimplemented from RecDef.

virtual void RecItem::copy_row_data ( const RecDef &  rdef, void *  row_data  ) const

virtual

Copy to given record set structure (MT_Safe). Type cast is not supported! Only exactly matched domains will be copied.

virtual void RecItem::deserialize ( InputStream &  ist )

virtual

Deserialize (internalize) the record data from given input stream with (own_memory==TRUE) or without (own_memory==FALSE) record definition.

Reimplemented from RecDef.

virtual void* RecItem::get_row_data ( ) const

virtual

Get (dynamically allocated by malloc) the whole item contents for UdbData::row_data (MT_Safe).

virtual const AnyValue& RecItem::get_value ( int  dmn_i ) const

virtual

Get value quickly but in multithread unsafe manner (MT_Unsafe).

const AnyValue & RecItem::get_value ( const char *  dname ) const

inline

Call the get_value(n2i(dname))

virtual void RecItem::get_value ( int  dmn_i, AnyValue &  av  ) const

virtual

Get value of given domain cell in multithread safe manner (MT_Safe).

void RecItem::get_value ( const char *  dname, AnyValue &  av  ) const

inline

Call the get_value(n2i(dname), av)

RecItem& RecItem::operator=

(

const RecItem &

r

)

Assign new record contents to this record. Assignment is available for the same structure records only.

virtual void RecItem::serialize ( OutputStream &  ost ) const

virtual

Serialize (externalize) the record data to given output stream with (own_memory==TRUE) or without (own_memory==FALSE) record definition.

Reimplemented from RecDef.

virtual void RecItem::set_row_data ( const void *  row_data )

virtual

Set the whole item contents from UdbData::row_data without test for record compatibility (MT_Safe).

virtual void RecItem::set_value ( int  dmn_i, const AnyValue &  av  )

virtual

Set value of given domain cell in multithread safe manner (MT_Safe).

void RecItem::set_value ( const char *  dname, const AnyValue &  av  )

inline

Call the set_value(n2i(dname), av)

virtual AnyValue& RecItem::value ( int  dmn_i )

virtual

Get access to a domain value quickly but in multithread unsafe manner (MT_Unsafe).

Member Data Documentation

AnyValue** RecItem::av

protected

Array of values, attached to record data.

bool RecItem::own_memory

protected

TRUE to delete rec_name and domains in destructor

void* RecItem::ptr_rec

protected

Pointer to record's data
