Method Detail

getID

public java.lang.String getID()

Get the unique id of the sequence.

Returns:

a String with the entry's id.

add

public ISchedulerEntry add(ISchedulerEntry entry)
                    throws WcmException

Appends a scheduler entry to the end of the sequence. The scheduler entry must not be added before, otherwise an exception will be raised.

Parameters:

entry - A scheduler entry

Returns:

the added scheduler entry

Throws:

WcmException - If adding fails.

add

public ISchedulerEntry add(int index,
                           ISchedulerEntry entry)
                    throws WcmException

Inserts a scheduler entry to the sequence at position index. The scheduler entry must not be added before, otherwise an exception will be raised.

Parameters:

index - The position of the entry in the sequence.

entry - A scheduler entry

Returns:

the added scheduler entry

Throws:

WcmException - If adding fails.

remove

public boolean remove(ISchedulerEntry entry)
               throws WcmException

Removes an entry from the sequence. If this sequence does not contain the entry, it is unchanged.

Parameters:

entry - The entry to remove.

Returns:

true if this list contained the specified element.

clear

public void clear()
           throws WcmException

Removes all of the elements from this sequence. This sequence will be empty after this call returns (unless it throws an exception).

toArray

public ISchedulerEntry[] toArray()

Converts the entries of this sequence to an array in the proper order.

Returns:

an array of scheduler entries

size

public int size()

Returns the number of entries in this sequence.

Returns:

the number of entries in this sequence.

isEmpty

public boolean isEmpty()

Returns true if this sequence contains no entries.

Returns:

true if this sequence contains no entries.

get

public ISchedulerEntry get(int index)

Returns the entry at the specified position in this sequence.

Parameters:

index - of element to return.

Returns:

the element at the specified position in this list.

contains

public boolean contains(ISchedulerEntry entry)

Returns true if this sequence contains the specified entry. More formally, returns true if and only if this sequence contains exactly one entry e such that (entry==null ? e==null : entry.equals(e)).
