Method Detail

values

public static ColumnComparatorNodeDialogPane.ComparatorMethod[] 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 (ColumnComparatorNodeDialogPane.ComparatorMethod c : ColumnComparatorNodeDialogPane.ComparatorMethod.values())
    System.out.println(c);

Returns:

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

valueOf

public static ColumnComparatorNodeDialogPane.ComparatorMethod 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

compare

abstract boolean compare(DataCell cell1,
                         DataCell cell2)

Compares both cell values using the comparator method.

Parameters:

cell1 - left column value

cell2 - right column value

Returns:

true, if both cell are equal with respect to the comparator

compareValue

int compareValue(DataCell cell1,
                 DataCell cell2)

Compares both cell values using the most common's super type comparator.

Parameters:

cell1 - first cell value

cell2 - second cell value

Returns:

true, if both are equal

getMethod

public static final ColumnComparatorNodeDialogPane.ComparatorMethod getMethod(String str)

Returns the comparator method, specified within the Enum.toString().

Parameters:

str - comparator method's toString return value

Returns:

a comparator method
