This class represents a data layer as a table.
It implements the H.service.extension.dataView.ITable
.<*, H.service.extension.customLocation.MetaInfo> interface.
Instances of this class must not be created directly via new operator. Instead a new instance can be
created via H.service.extension.customLocation.Service#createLayer method.
Throws:
-
If directly called via
newoperator.

Methods
-
To add cells at the bottom of the table. Use this method to create rows for already existing bulk data.
Name Type Description cellsArray.<(string|!H.geo.AbstractGeometry)> The cell values of the row(s) in the order of the table's column names.
Throws:
-
if the number of passed cells is not a multiple of the number of the table's columns.
Returns:
Type Description number the index of the appended row. If multiple rows were appended, then the index of the first one. Example
rowIndex = table.addCells([ row1Col1Value, row1Col2Value, '', row1Geometry, row2Col1Value, row2Col2Value, '', row2Geometry ]); firstAppendedRow = table.getRow(rowIndex); -
-
addRow ()H.service.extension.customLocation.Table.Row Deprecated : since 3.1.63.0
-
To add a new row at the bottom of the table. All cells of the row are initialized with a
nullvalue.Returns:
Type Description H.service.extension.customLocation.Table.Row the added row. -
concat (var_args)H.service.extension.dataView.ITable.<C, M> Deprecated : since 3.1.63.0
-
To merge two ore more tables. It doesn't change the existing table, but instead returns a new one. The concat method creates a new ITable consisting of the rows in the object on which it is called, followed in order by, for each argument, the rows of that argument. in the arguments list.
Name Type Description var_argsH.service.extension.dataView.ITable.<C, M> repeatable Tables to concatenate into a new table.
Throws:
-
if the tables have a different columns.
Returns:
Type Description H.service.extension.dataView.ITable.<C, M> the resulting table. -
-
To get the cell value at the given row index and named column
Name Type Description rowIndexnumber The zero-based index of the cell's row.
columnNamestring The name of the cell's column.
Returns:
Type Description C | undefined The value of the specified cell or undefinedif the given row index is out of range or a column of the given name doesn't exists. -
getColumn (columnName)!H.service.extension.dataView.IColumn.<C> | undefined Deprecated : since 3.1.63.0
-
To get the column with the given name.
Name Type Description columnNamestring The name of the column.
Returns:
Type Description !H.service.extension.dataView.IColumn.<C> | undefined The specified column or undefinedif no column with the given name exists. -
To get a ordered list of all column names.
Returns:
Type Description Array.<string> the list of the column names. -
To get meta information of the table.
Returns:
Type Description M -
getRow (rowIndex)!H.service.extension.dataView.IRow.<C> | undefined Deprecated : since 3.1.63.0
-
To get the row at the given index.
Name Type Description rowIndexnumber The zero-based index of the row.
Returns:
Type Description !H.service.extension.dataView.IRow.<C> | undefined The specified row or undefinedif the given row index is out of range. -
To get the number of rows
Returns:
Type Description number -
getRows ()Array.<!H.service.extension.customLocation.Table.Row> Deprecated : since 3.1.63.0
-
Returns a collection of all existing rows of the table.
Returns:
Type Description Array.<!H.service.extension.customLocation.Table.Row> -
To set the value of the cell at the specified row and column.
GEOMETRY_IDcell of an existing row should not be modified to not cause data inconsistency.Throws:
-
if a row with the given index or a column with the given name doesn't exist.
Example
// Set value of the column with the specified name for the first row table.setCell(0, "COMPANY", "HERE Technologies"); table.setCell(0, "WKT", new H.geo.Point(52.5309, 13.3849)); -
