AttributeColumn joinWithSeparatorMerge(AttributeTable table, AttributeColumn[] columnsToMerge, AttributeType newColumnType, java.lang.String newColumnTitle, java.lang.String separator)
Joins various columns of any type into a new column using the given separator string (or null).
If the specified column type is null, the new created column will have STRING
AttributeType
by default.
table
- Table of the columns to mergecolumnsToMerge
- Columns to mergenewColumnType
- Type for the new column. If null, STRING
will be used by defaultnewColumnTitle
- Title for the new columnseparator
- Separator to put between each value
AttributeColumn mergeNumericColumnsToTimeInterval(AttributeTable table, AttributeColumn startColumn, AttributeColumn endColumn, double defaultStart, double defaultEnd)
Merge 1 or 2 columns creating a time interval for each row. Values of the columns will be expected as numbers
Only one of the 2 column could be null, and its corresponding start/end default will be used.
Columns can be of any type. If not numeric, their values will be parsed.
Default start and end values will be used when the columns don't have a value or it can't be parsed to a double.
When start > end for any reason:

- Table of the columns, can't be null or wrongstartColumn
- Column to use as start valueendColumn
- Column to use as end valuedefaultStart
- Default start valuedefaultEnd
- Default end value
AttributeColumn mergeDateColumnsToTimeInterval(AttributeTable table, AttributeColumn startColumn, AttributeColumn endColumn, java.text.SimpleDateFormat dateFormat, java.lang.String defaultStartDate, java.lang.String defaultEndDate)
Merge 1 or 2 columns creating a time interval for each row. Values of the columns will be expected as dates in the given date format
Only one of the 2 column could be null, and its corresponding start/end default will be used.
Columns can be of any type.
Default start and end values will be used when the columns don't have a value or it can't be parsed to a date. If a default value can't be parsed to a date, infinity will be used as default instead.
When start > end for any reason:

- Table of the columns, can't be null or wrongstartColumn
- Column to use as start valueendColumn
- Column to use as end valuedateFormat
- Format for the dates, can't be nulldefaultStartDate

- Default date to use as end if it can be parsed
AttributeColumn booleanLogicOperationsMerge(AttributeTable table, AttributeColumn[] columnsToMerge, AttributeColumnsMergeStrategiesController.BooleanOperations[] booleanOperations, java.lang.String newColumnTitle)
Strategy to apply only to all boolean columns. Merges various columns into a new boolean column allowing to define each operation to apply between each pair of columns to merge.
The length of the operations array must be the length of the columns array-1, or IllegalArgumentException will be thrown.
