Enum Constant Detail

METHOD_INVOCATIONS

public static final Builder.Feature METHOD_INVOCATIONS

Method invocations as in ${foo.bar(1)} as specified in JSR 245, maintenance release 2. The method to be invoked is resolved at evaluation time by calling ELResolver#invoke(javax.el.ELContext, Object, Object, Class[], Object[]).

NULL_PROPERTIES

public static final Builder.Feature NULL_PROPERTIES

For some reason we don't understand, the specification does not allow to resolve null property values. E.g. ${map[key]} will always return null if key evaluates to null. Enabling this feature will allow JUEL to pass null to the property resolvers just like any other property value.

VARARGS

public static final Builder.Feature VARARGS

Allow for use of Java 5 varargs in function calls.

Method Detail

values

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

Returns:

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

valueOf

public static Builder.Feature 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
