Private _columnPrivate _columnThe column offset cache, starting with row _columnOffsetsStartingRow
The index of the first character in the data string for row r, column c is _columnOffsets[(r-this._columnOffsetsStartingRow)*numColumns+c]
Private _columnThe row that _columnOffsets[0] represents.
Private _delayedPrivate _delimiterPrivate _donePrivate _headerThe header strings.
Private _initialThe number of rows to parse initially before doing a delayed parse of the entire data.
Private _isPrivate _maxThe maximum number of rows to parse when there is a cache miss.
Private _parserPrivate _quotePrivate _quotePrivate _rawPrivate _readyPrivate _rowPrivate _rowPrivate _rowThe index for the start of each row.
Private _startedThe delimiter between entries on the same row.
A boolean determined by whether parsing has completed.
The header strings.
The initial chunk of rows to parse.
Whether this model has been disposed.
The string representation of the data.
The delimiter between rows.
Private _computeCompute the row offsets and initialize the column offset cache.
The last row to parse, from the start of the data (first row is row 1).
This method supports parsing the data incrementally by calling it with incrementally higher endRow. Rows that have already been parsed will not be parsed again.
Private _getPrivate _resetProtected emitEmit the changed signal for the data model.
Subclasses should call this method whenever the data model has changed so that attached data grids can update themselves.
Get the metadata for a cell in the data model.
The cell region of interest.
The row index of the cell of interest.
The column index of the cell of interest.
The metadata for the specified cell.
The returned metadata should be treated as immutable.
This method is called often, and so should be efficient.
The default implementation returns {}.
Parse the data string asynchronously.
It can take several seconds to parse a several hundred megabyte string, so we parse the first 500 rows to get something up on the screen, then we parse the full data string asynchronously.
A data model implementation for in-memory delimiter-separated data.
Notes
This model handles data with up to 2**32 characters.
