currentRecordNumber

public int currentRecordNumber()

Return the current record number.

Returns:

the current record number.

getClassAtom

public String getClassAtom()

Description copied from class: Obj

Returns the atomic name of this element's class.

Overrides:

getClassAtom in class Obj

Returns:

the class name as an interned string.

getClassName

public String getClassName()

Description copied from class: Obj

Gets the name of this object's class. Overriden by derived classes such as Element that have a local name that may be returned instead.

Overrides:

getClassName in class Obj

Returns:

the class name.

getScriptProperty

public Arg getScriptProperty(String sPropertyName)

getScriptTable

public ScriptTable getScriptTable()

Overrides:

getScriptTable in class Obj

gotoRecord

public void gotoRecord(int newRecord)

Move the current record to a specific record.

Parameters:

newRecord - the absolute record number.

isDefined

public boolean isDefined()

Determine if the data window is currently in a defined (valid) state. A data window is in this state if the current record index indicates a valid record. A data window is not defined if there are no records, or if the current record index has been positioned beyond the end of the records.

Returns:

true if dataWindow is defined, false otherwise.

recordOffset - the number of records from the current record, positive or negative (0 returns current record).

Returns:

the requested record.

recordAbsIndex

public int recordAbsIndex(int recordOffset)

recordsAfter

public int recordsAfter()

Determine the number of records after the current record in this window.

Returns:

the number of records after the current record.

recordsBefore

public int recordsBefore()

Determine the number of records before the current record in this window.
