Enclosing interface:

JexlUberspect

public static enum JexlUberspect.JexlResolver
extends java.lang.Enum<JexlUberspect.JexlResolver>
implements JexlUberspect.PropertyResolver

The various builtin property resolvers.

Each resolver discovers how to set/get a property with different techniques; seeking method names or field names, etc.

Method Detail

values

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

Returns:

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

valueOf

public static JexlUberspect.JexlResolver 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
