Method Detail

values

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

Returns:

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

valueOf

public static ViewEnum valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

getNamespace

public java.lang.String getNamespace()

Returns namespace that the object belongs to.

Returns:

namespace

getName

public java.lang.String getName()

Returns name of the view that can be used to reference the view in a view expression.

Returns:

short name of view

getMergeView

public ViewEnum getMergeView()

Returns the enumeration value of the view for merging the data generated by another view.

Returns:

view enum for the merge view

getFactoryClass

public java.lang.Class getFactoryClass()

Returns a view's factory class.

Returns:

class of view factory

forName

public static ViewEnum forName(java.lang.String namespace,
                               java.lang.String name)

Returns the view enumeration value given the name of the view.

Parameters:

namespace - is the namespace name of the view

name - is the short name of the view as used in view expressions

Returns:

view enumeration value, or null if no such view name is among the enumerated values
