Constructor Detail

BaseProxy

protected BaseProxy(NotesProxyFactory theFactory,
                    DBase theParent,
                    lotus.domino.Base object,
                    DNotesMonitor monitor)

Creates a new DBaseImpl object.

Parameters:

theFactory - the controlling factory

theParent - the parent object

object - the notes object

monitor - the monitor

Method Detail

getNotesObject

protected final lotus.domino.Base getNotesObject()

Returns the Notes object associated with an instance.

Returns:

associated Notes object

clearNotesObject

protected final void clearNotesObject()

Clears the associated notes object, used during dispose/recycle operations.

getParent

protected final DBase getParent()

Returns the parent object.

Returns:

the parent object or null if no parent available

getFactory

protected final NotesProxyFactory getFactory()

Returns the factory corresponding to this instance.

Returns:

the corresponding factory

toStringGeneric

public final java.lang.String toStringGeneric()

Utility method for the toString method of derived classes. Returns a string representation of the object.

Returns:

string representation of the object

See Also:

Object.toString()

convertListToVector

protected final java.util.Vector convertListToVector(java.util.List list)

Convert List to Vector.

If the implementation of the List interface is a Vector, this vector is used unchanged, else the references of elements of the List are copied to a new result Vector.

Parameters:

list - a list

Returns:

a Vector containing the elements of the list argument

convertVectorToList

protected final java.util.List convertVectorToList(java.util.Vector vector)

Deprecated. the usage of the method convertVectorToList() is not needed and impacts performance

Convert Vector to List. A Vector does also implement the List interface. But it is synchronized. Therefore this conversion method provides a real List that is not synchronized.

Parameters:

vector - a vector

Returns:

a List

convertNotesDateTimesToCalendar

protected final java.util.List convertNotesDateTimesToCalendar(java.util.List list)

Converts every occurrence of a DateTime object to a java.util.Calendar instance.

The created DateTime objects must get recycled somewhen later, when they are not needed anymore. To ensure this, the calling method must call the method recycleDateTimeList() after usage.

Lists are processed recursivly; this is e.g. needed for column values that might contain value lists in the list of column values.

Parameters:

list - the list to convert its content

Returns:

List a new List with the same elements in same order, but converted dates

convertCalendarsToNotesDateTime

protected final java.util.List convertCalendarsToNotesDateTime(java.util.List list)

Converts every occurrence of a java.util.Calendar or java.util.Date in a List to a DateTime instance.

ATTENTION:
The created DateTime objects must get recycled somewhen later, when they are not needed anymore. To ensure this, the calling method must call the method recycleDateTimeList() after usage.

Example

 List keys;
 // initialize and fill list with Date objects and others
 List convertedList = convertDatesToNotesDateTime(keys);
 // now the list contains Notes DateTime objects.
 // do something with the list
 recycleDateTimeList(convertedKeys);
 

Parameters:

list - the list to convert its content

Returns:

List a new List with the same elements in same order, but converted dates

recycleDateTimeList

protected final void recycleDateTimeList(java.util.List list)

Recycles all Notes DateTime objects in a list.

The list can have mixed content and must not contain only DateTime objects. But only DateTime objects are recycled.

Parameters:

list - any list implementation

getDSession

protected final SessionProxy getDSession()

Returns the Domingo session that created the current object.

Returns:

Domingo session of current object

createDateTime

protected final lotus.domino.DateTime createDateTime(java.util.Calendar calendar)

Creates a Notes DateTime instance from a java.util.Calendar. Adapter to InternationalProxy. This is a convenience method to allow every object to convert dates.

Parameters:

calendar - the calendar to convert

Returns:

DateTime object representing the same point in time

createDateRange

protected final lotus.domino.DateRange createDateRange(java.util.Calendar calendar1,
                                                       java.util.Calendar calendar2)

Creates a Notes DateRange instance from two java.util.Calendars. Adapter to InternationalProxy. This is a convenience method to allow every object to convert dates.

Parameters:

calendar1 - the start calendar to convert

calendar2 - the end calendar to convert

Returns:

DateTime object representing the same point in time

See Also:

InternationalProxy.createDateRange(Calendar, Calendar)

createCalendar

protected final java.util.Calendar createCalendar(lotus.domino.DateTime dateTime)

Converts a Notes DateTime object into a Calendar.

Milli seconds are cleared in all cases.

Adapter to InternationalProxy. This is a convenience method to allow every object to convert dates.

Parameters:

dateTime - a Notes DateTime object

Returns:

a Calendar

See Also:

InternationalProxy.createCalendar(DateTime)

checkSession

protected final void checkSession(lotus.domino.DateTime dateTime)

Checks and monitors an error if a DateTime object doesn't have a parent session.

Parameters:

dateTime - the DateTime object to check

finalize

protected final void finalize()
                       throws java.lang.Throwable

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable - the Exception raised by this method

See Also:

Object.finalize()

refereceHashCode

public final int refereceHashCode()

Returns the hashCode of the referenced Notes object.

Returns:

hashCode of referenced Notes object

See Also:

Object.hashCode()

toStringIntern

public static java.lang.String toStringIntern(java.lang.Object object)

Returns a string representation of the object. This method returns a string that "textually represents" this object. The result is a concise but informative representation that is easy for a person to read.

The toStringIntern method returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 object.getClass().getName() + '@' + Integer.toHexString(object.hashCode())
 

Parameters:

object - the reference object to use.

Returns:

a string representation of the object.
