Detailed Description

A data model containing a list of log record links. This is used for displaying a ZLogMap object.

ZLogReclinkModel encapsulates a data model representing the log record links in a ZLogMap object. ZLogMap objects contain compressed log links where consecutive log records are represented as a single data item to reduce the size of ZLogMap objects in memory. ZLogReclinkModel expands the compressed links from ZLogMap into one item per log record for display purposes.

Each ZLogReclinkModel object is synchronized with its source search or bookmark so that changes to the source are propagated to the data model automatically. The data model encapsulated by ZLogReclinkModel objects is implicitly shared. When all references to the shared, synchronized data model are gone it is automatically destroyed.

getValue [1/2]

QVariant Zbl::ZLogReclinkModel::getValue ( int  role, int  row  )

slot

Obtains the value of the specified data cell.

Parameters

role	the role whose value to return
row	the cell's zero-based row number

Returns

the value stored in the specified cell

getValue [2/2]

QVariant Zbl::ZLogReclinkModel::getValue ( int  role, int  row, int  column  )

slot

Obtains the value of the specified data cell.

This method is provided for compatibility with ZTableModel. It ignores the third dimension parameter 'column'.

Parameters

role	the role whose value to return
row	the cell's zero-based row number
column	this parameter is ignored

Returns

the value stored in the specified cell
