The ifArray interface provides the following:
• Peek() As Dynamic: Returns the last (highest index) array entry without removing it.
• Pop() As Dynamic: Returns the last (highest index) entry and removes it from the array.
• Push(a As Dynamic): Adds a new highest index entry to the end of the array
• Shift() As Dynamic: Removes index zero from the array and shifts all other entries down by one unit.
• Unshift(a As Dynamic): Adds a new index zero to the array and shifts all other entries up by one unit.
• Delete(a As Integer) As Boolean: Deletes the indicated array entry and shifts all above entries down by
one unit.
• Count() As Integer Returns the index of the highest entry in the array plus one (i.e. the length of the array).
• Clear(): Deletes every entry in the array.
• Append(a As Object): Appends one roArray to another. If the passed roArray contains entries that were never
set to a value, they are not appended.
Note: The two appended objects must be of the same type.
The ifArrayGet interface provides the following:
• GetEntry(a As Integer) As Dynamic: Returns an array entry of a given index. Entries start at zero. If an
entry that has not been set is fetched, Invalid is returned.
The ifArraySet interface provides the following:
• SetEntry(a As Integer, b As Dynamic): Sets an entry of a given index to the passed type value.
Example:
list = CreateObject(“roList”)
list.AddTail(“a”)
list.AddTail(“b”)
list.AddTail(“c”)
