Parameters:

rme - RasterMapEntry for the web-sourced overlay layer

now - current time in milliseconds since Jan 1970 UTC

Returns:

the Date when the loaded raster image will expire and should be loaded again

Throws:

java.io.IOException - if image file cannot be downloaded

add

public int add(RasterMapEntry rme)

Add the specified RasterMapEntry to the persisted list of raster map overlays.

Parameters:

rme - RasterMapEntry to add

Returns:

Parameters:

index - zero-based int index of the record to remove

getColumnClass

public java.lang.Class<?> getColumnClass(int columnIndex)

Returns the data Class for the specified column.

Specified by:

getColumnClass in interface javax.swing.table.TableModel

Overrides:

getColumnClass in class javax.swing.table.AbstractTableModel

Parameters:

columnIndex - the column being queried

Returns:

the Class object for the column's data

getColumnName

public java.lang.String getColumnName(int column)

Returns the localized name for the column.

Specified by:

getColumnName in interface javax.swing.table.TableModel

Overrides:

getColumnName in class javax.swing.table.AbstractTableModel

Parameters:

column - the column being queried

a string containing the name of column

isCellEditable

public boolean isCellEditable(int rowIndex,
                              int columnIndex)

Indicate which columns can be edited.

Specified by:
