# class ValueArray

ValueArray adds methods to arrays to generically add, set and get tuples, through real values.

See also: Array

# Properties

Property Description
AlternativeName A string that can be used to identify the array in collections. (Inherited from Array)
ItemCount The number of individual items in the array. Warning! Do not confuse this count with the count of tuples, they are only the same if TupleSize is equal to 1, i.e. when the tuples are exactly one component each. Also note that the item count should be a multiple of TupleSize. Note that the total number of items cannot exceed INT_MAX. (Inherited from Array)
Name The name of the ValueArray object. (Inherited from Object)
TupleCount The tuple count, meaning how many tuples are in the array. If resized to larger array, the new tuples will not be set to anything. (Inherited from Array)
TupleSize The tuple size, meaning how many items of the underlying data type is in a tuple. The tuple size must be set before the array is populated. (Inherited from Array)

# Methods

Method Description
AddObserver Adds a user-defined observer object to the interface, that will receive events from the interface. (Inherited from Object)
AppendArray Appends an array to this array. The array must be a descendant of ValueArray. For best performance, append arrays of the same basic type. (Inherited from Array)
Clear Clears the array and sets the tuple count to 0. Tuple size and name remains the same though. (Inherited from Array)
CompareTuples CompareTuples compares a tuple in this array with a tuple in another array. Returns 0 if the tuples are identical, 1 if an element in this array tuple in ascending order is larger and -1 if smaller. (Inherited from Array)
CopyRange CopyRange copies a range of tuples from a source array into this array. The arrays must have the same tuple size and base type. This array must be resized to hold the tuples before copying. The basetypes are listed in EBaseTypes. (Inherited from Array)
CopyTuple CopyTuple copies one tuple in a source array to a tuple in this array. Both the dest_id and the source_id must exist in the arrays. This array can be used as the source array to copy within the array. (Inherited from Array)
DeepCopy Copies data from another array. The arrays must have the same underlying data types. (Inherited from Array)
ExtractTuples Extracts tuples from the array. Note that the destination array must have the same classtype and have the same tuple size as the source array. (If both arrays are decendants of ValueArray, they can be of different types, but the conversion is slow). (Inherited from Array)
GetBaseType Returns the id of the basic type that the array is based on The ids are listed in the BaseTypes enumeration. (Inherited from Array)
GetClass Get the name of the ValueArray class. (Inherited from Object)
GetMaxItemId Returns the id of the last item that is in the array. The id returned is equal to (ItemCount - 1). Warning! Do not confuse this id with the id of a tuple, they are only the same if TupleSize is equal to one, i.e. when the tuples are exactly one component each. (Inherited from Array)
GetMaxTupleId Returns the id of the tuple last in the list. If the array is empty, the value is unspecified. Note: GetMaxTupleId() always returns (GetTupleCount()-1) as a signed id. (Inherited from Array)
GetRealItem GetRealItem() retrieves the item at position id. The id is the id of the item, not the tuple the item belongs to. GetRealItem() converts the value from the actual underlying data type to a real.
IndexedCopy Copies tuples from a source array through an id table. The id table dictates the order in which the tuples are to be copied to this array. E.g. If the first item in the id table has the value 14, then the tuple with id 14 in the source array will be copied to the first tuple in this array. Note: All ids in the id table must be valid ids of tuples in the source array. The id table is assumed to have a tuple size of 1. The source array and this array must have the same underlying data type, and have the same tuple size. The array must be large enough to hold the copied data. (Inherited from Array)
IsA Returns true if ValueArray is a or is a descendant of the class named as the type parameter. (Inherited from Object)
IsEmpty Returns true if the list is empty. (Inherited from Array)
IsNull Returns true if the ValueArray object is invalid. (Inherited from Object)
IsSameObjectAs Returns true if the ValueArray object is valid. (Inherited from Object)
NewCopy Creates a new array with the same underlying data type, size and tuple settings as this array. To also copy the actual data, set copy_data to true. (Inherited from Array)
NewPackedCopy Like NewCopy, NewPackedCopy creates an array with the same underlying data and tuple settings as the source array. However, NewPackedCopy only copies unique tuples, and if the index_array parameter is set, this index array will contain the same number of tuples as the source array, and with the ids of a specific tuples within the new copy of the array. (Inherited from Array)
NonNull Returns true if the ValueArray object is valid. (Inherited from Object)
PrintInfo Prints the content/info of the ValueArray object to the log. (Inherited from Object)
RemoveObserver Removes a previously added observer object. (Inherited from Object)
SetRealItem SetRealItem() sets the item at position id. The id is the id of the item, not the tuple the item belongs to. SetRealItem() converts the value from real to the actual underlying data type.

# Static methods

Method Description
IsClassA Returns true if the class is a or is a descendant of the class named as the type parameter. (Inherited from Object)
SafeCast SafeCast makes sure the input object is of a class that can be cast into spValueArray, and if this is the case, returns the object cast into spValueArray. (Inherited from Object)
