Enum FilterOrder

java.lang.Object

java.lang.Enum<FilterOrder>

de.gematik.combine.filter.FilterOrder

All Implemented Interfaces:

Serializable, Comparable<FilterOrder>

public enum FilterOrder
extends Enum<FilterOrder>

Defines a sorting order for TableFilter implementations.

Enum Constant Summary

Enum Constants

Enum Constant	Description
DISTINCT_COLUMN	The DistinctColumnFilter operates on the whole table and can interfere with other filters.
DOUBLE_LINEUP	The DoubleLineupFilter operates on the whole table and can interfere with other filters.
MAX_ROWS	The MaxRowFilter cuts the table after a defined number of rows and does not evaluate any other properties.
MAX_SAME_VALUE_COLUMN_PROPERTY	The MaxSameColumnPropertyFilter operates on the whole table and can interfere with other filters.
ROW_ONLY	Filters that operate only on rows do not interfere with other filters.
SHUFFLE	Shuffling should be applied before all filters that operate on the whole table.

Enum Constant Detail

ROW_ONLY

public static final FilterOrder ROW_ONLY

Filters that operate only on rows do not interfere with other filters. Therefore, they can be applied early in filtering.

SHUFFLE

public static final FilterOrder SHUFFLE

Shuffling should be applied before all filters that operate on the whole table.

MAX_SAME_VALUE_COLUMN_PROPERTY

public static final FilterOrder MAX_SAME_VALUE_COLUMN_PROPERTY

The MaxSameColumnPropertyFilter operates on the whole table and can interfere with other filters. It can filter out rows that would not be filtered if MaxSameColumnPropertyFilter is applied later. Therefore, the MaxSameColumnPropertyFilter should be applied late in filtering process.

DISTINCT_COLUMN

public static final FilterOrder DISTINCT_COLUMN

The DistinctColumnFilter operates on the whole table and can interfere with other filters. It can filter out rows that would not be filtered if DistinctColumnFilter is applied later. Therefore, the DistinctColumnFilter should be applied late in filtering process.

DOUBLE_LINEUP

public static final FilterOrder DOUBLE_LINEUP

The DoubleLineupFilter operates on the whole table and can interfere with other filters. It can filter out rows that would not be filtered if DoubleLineupFilter is applied later. Therefore, the DoubleLineupFilter should be applied late in filtering process.

MAX_ROWS

public static final FilterOrder MAX_ROWS

The MaxRowFilter cuts the table after a defined number of rows and does not evaluate any other properties. Therefore, the MaxRowFilter should be applied as last filter.

public final int orderKey

Method Detail

values

public static FilterOrder[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (FilterOrder c : FilterOrder.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static FilterOrder valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getFilterOrderFor

public static FilterOrder getFilterOrderFor(TableFilter tableFilter)

getOrderKey

public int getOrderKey()

getFilters

public Set<Class<? extends TableFilter>> getFilters()
