-
Gets the actual count of the result set for the specified axis. Valid values are "row" and "column".
Parameters:
Name |
Type |
Description |
axis |
string
|
the axis in which to inquire the actual count of the result set.
|
Returns:
the actual count of the result set for the specified axis.

getData(indexes) : {Object}
-
Gets the data of the specified index. An error is throw when 1) the range is not yet available
2) the index specified is out of bounds. The indices are absolute within the entire data set, not just this cell set
Parameters:
Name |
Type |

Properties:

Type |
Description |
indexes.column |
number
|
the index of the column axis.
|
indexes.row |
number
|
the index of the row axis.
|
Returns:
the data object for the specified index.

Object
-
getExtent(indexes) : {Object}
-
Gets the extent of a particular row/column index within the context of the cellSet.
Extent is defined as the number of indexes along the appropriate axis spanned by the cell.
If the extent extends beyond the start and end of the requested cell range the extent should be trimmed to the edge of the requested cell range and the object for {'more': {'before', 'after'}} should have the value appropriate boolean set.
Parameters:
Name |
Type |
Description |
indexes |
Object
|
the index of each axis in which we want to retrieve the data from.
|
Properties:
Name |
Type |
Description |
indexes.column |
number
|
the index of the column axis.
|
indexes.row |
number
|
the index of the row axis.
|
Returns:
an object containing two properties row and column. Each of those properties has two sub properties:
extent: the number of absolute indexes spanned by the cell at this index
bounded by the edges of the result set for the specified axis.
more: object with keys 'before'/'after' and boolean values true/false representing whether
there are more indexes before/after what is available in the cellSet

Object
-
-
Gets the metadata of the specified index. An error is throw when 1) the range is not yet available
2) the index specified is out of bounds. The indices are absolute across the entire data set not just within the cell set
Parameters:
Name |
Type |
Description |
indexes |
Object
|
the index of each axis in which we want to retrieve the metadata from.
|
Properties:
Name |
Type |
Description |
indexes.column |
number
|

|
indexes.row |
number
|
the index of the row axis.
|
Returns:
the metadata object for the specific index. The metadata that the DataGrid supports are:
1) keys - the key (of each axis) of the cell.

-
getStart(axis) : {number}
