Modifier and Type	Method and Description
int	moveFirst() Moves the enumeration cursor to the first entry in the enumeration.
int	moveLast() Moves the enumeration cursor to the last entry in the enumeration.
int	moveTo(java.lang.String target) Moves the enumeration cursor position to the entry that most matches the specified target name.

Method Detail

moveFirst

int moveFirst()
       throws SnapinException

Moves the enumeration cursor to the first entry in the enumeration.

Returns:

The new enumeration cursor index

Throws:

SnapinException - Thrown by the service provider when an error occurs.

moveLast

int moveLast()
      throws SnapinException

Moves the enumeration cursor to the last entry in the enumeration.

Returns:

The new enumeration cursor index

Throws:

SnapinException - Thrown by the service provider when an error occurs.

moveTo

int moveTo(java.lang.String target)
    throws SnapinException

Moves the enumeration cursor position to the entry that most matches the specified target name.

If an exact match is not found, then the enumeration cursor position is moved to the entry which matches the target name the closest.

Parameters:

target - The name of the entry to which the enumeration cursor position will be moved.

Returns:

The new enumeration cursor position

Throws:

SnapinException - Thrown by the service provider when an error occurs.

previous

ObjectEntry previous()
              throws SnapinException

Returns the previous entry in the enumeration.

Returns:

The entry previous.

Throws:

SnapinException - Thrown by the service provider when an error occurs.

setBlockSize

void setBlockSize(int size)

Sets the most frequent size in which the consumer of the enumeration will request entries from the enumeration.

If the consumer of the enumeration will call getNext() and getPrev() with a count parameter that is frequently limited to a given size, then setBlockSize() may be called to inform the enumeration of the consumers intentions.

The enumeration implementation may use the block size to allow caching more tailored to the consumers needs. In this case, the consumer may set the block size equal to one screen full of entries.

The block size may be changed at any time during the life of the enumeration

Parameters:

size - The block size.

refresh

void refresh()

Indicates that the enumeration needs to flush any cached data.
