IDataView Class

A view on multi-dimensional data.

Views can be created using openView, on an IMultiDimData. This method requires a filter that can be created using createFilter (on the IMultiDimData).

Public Methods

	Name	Description
	createElementValue	Creates an IElement to hold a value. Applies to element valued data only.
	createIterator	Creates an IIterator to iterate over the data. By default, 100 tuples are cached. Also initializes the iterator: Moves the current position to before the beginning of the data; a subsequent next call will find the first non-default position.
	createTuple	Creates a new IIterator to iterate over the data. By default, 100 tuples are cached.
	flush	Flushes the buffered changes to this data; if possible, this will be performed in the background.
	getDouble	Returns double the value for the provided tuple. Applies to double valued data only.
	getElement	Returns double the value for the provided tuple. Applies to double valued data only.
	getIndexDomain	Returns a reference to the index domain on the provided dimension.
	getInt	Returns the int value for the provided tuple. Applies to integer valued data and element valued data of which the range is a subset of Integers.
	getString	Returns the String value for the provided tuple. Applies to string valued data, and element valued data of which the range is not a subset of Integers.
	insert	Assigns the specified value to the specified position. When the position did not exist it the index domain, it will be created.
	setValue	Sets the specified position to the value.
	setValues	Sets the values for the complete domain of the data, by passing the values as an array and specifying the number of elements in the array.
	setValuesCMO	Sets the values for the complete domain of the data, by passing the values as an array and specifying the number of elements in the array.
	tupleCompatible	Verifies that the dimension and underlying root sets of the ITuple are applicable on this IData. Only structure is validated; the values themselves are not considered.
	tupleValid	Verifies that the current values are valid in the domain of the IData.
