Feature enumeration type.

Enum Constant Summary

METHOD_INVOCATIONS
Method invocations as in ${foo.bar(1)} are a JUEL extension.

NULL_PROPERTIES
For some reason we don't understand, the specification does not allow to resolve null property values.

Enum Constant Detail

METHOD_INVOCATIONS

public static final Builder.Feature METHOD_INVOCATIONS

Method invocations as in ${foo.bar(1)} are a JUEL extension. The method to be invoked is resolved at evaluation just like properties. That is, a specialized resolver will have to be provided at evaluation time.

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.

Method Detail

values

public static final Builder.Feature[] values()

Returns an array containing the constants of this enum type, in the order they're 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're declared

valueOf

public static Builder.Feature 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
