Constructor Details

AssociativeDataTable

public AssociativeDataTable(TableHandle tableHandle,
 String keyColumn,
 String valueColumn,
 Class<KEY> keyColumnType,
 Class<VALUECOLUMN> valueColumnType,
 PlotInfo plotInfo)

Creates an AssociativeDataSwappableTable instance. Key are in the keyColumn of the table held by tableHandle. Their associated values are in the valueColumn. The data type of the keys is specified by keyColumnType. The data type of the values is specified by valueColumnType.

Parameters:

tableHandle - holds the underlying table

keyColumn - column in the table which holds the key values

valueColumn - column in the table which holds the values associated with the keys

keyColumnType - data type of the keys

valueColumnType - data type of the values

plotInfo - plot information

Throws:

RequirementFailure - tableHandle, keyColumn, and valueColumn must not be null

IllegalArgumentException - keyColumn and valueColumn must be columns in swappableTable

RuntimeException - the specified data types must match the data types of the corresponding columns
