Detailed Description

A ColumnDefinition Defines the values in the column of a Table. These values have a domain and a range. Additionally the index and the name of the defined column are kept. For ease of used the changed and multiple flags are used. The changed flag will be set whenever something changes within this ColumnDefinition, the multiple flag will be set when

Constructor & Destructor Documentation

ColumnDefinition::ColumnDefinition

(

)

Constructs an empty ColumnDefinition

ColumnDefinition::ColumnDefinition	(	const ColumnDefinition &	def,
		quint32	index
	)

Copy constructor. Copies the fields of the supplied ColumnDefinition onto a new one.
sets the multiple and changed flags to false.
Does not copy the index. so a new one must be specified
the index cannot be negative

Parameters

def	the original ColumnDefinition
index	the new index

ColumnDefinition::ColumnDefinition	(	const QString &	name,
		const DataDefinition &	def,
		quint64	colindex
	)

Constructs a new ColumnDefinition using a name, DataDefinition an index.
The index cannot be negative.

DataDefinition

Parameters

name	the name of the new ColumnDefinition (recommended not to be null/ """);
def	The Datadefinition of the new ColumnDefinition
colindex	the index of the new ColumnDefinition

ColumnDefinition::ColumnDefinition	(	const QString &	nm,
		const IDomain &	dom,
		quint64	colindex = i64UNDEF
	)

Creates a new ColumnDefinition using a name, a Domain and an index.
Because only a Domain is used the range will not be set.
The index cannot be negative.

Parameters

nm
dom
colindex

Member Function Documentation

void ColumnDefinition::changed

(

bool
