All Implemented Interfaces:

Serializable, Comparable<ViewFieldEnum>

public enum ViewFieldEnum
extends Enum<ViewFieldEnum>

Enumerates the valid values for each view's public fields. The name of the field or property can be used to obtain values from the view rather than using the hardcoded String value for the field.

Method Detail

values

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

Returns:

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

valueOf

public static ViewFieldEnum 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

getName

public String getName()

Returns the field name of fields that contain data within a view's posted objects.

Returns:

field name for use with DataSchema to obtain values out of objects.
