Methods

getCount(axis) : {number}

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.
Type
number

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 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:
the data object for the specified index.
Type
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
Type
Object

getMetadata(indexes) : {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 the index of the column axis.
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.
Type
Object

getStart(axis) : {number}

Gets the start index 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 start index of the result set for the specified axis.
Type
number
