INSTANCE

public static final MapValueResolver INSTANCE

A singleton instance.

Method Detail

values

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

Returns:

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

valueOf

public static MapValueResolver 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

resolve

public java.lang.Object resolve(java.lang.Object context,
                                java.lang.String name)

Description copied from interface: ValueResolver

Resolve the attribute's name in the context object. If a ValueResolver.UNRESOLVED is returned, the context stack will continue with the next value resolver in the chain.

Specified by:

resolve in interface ValueResolver

Parameters:

context - The context object. Not null.

name - The attribute's name. Not null.

Returns:

A ValueResolver.UNRESOLVED is returned, the context stack will continue with the next value resolver in the chain. Otherwise, it returns the associated value.

resolve

public java.lang.Object resolve(java.lang.Object context)

Description copied from interface: ValueResolver

Resolve the the context object by optionally converting the value if necessary. If a ValueResolver.UNRESOLVED is returned, the context stack will continue with the next value resolver in the chain.

Specified by:

resolve in interface ValueResolver

Parameters:

context - The context object. Not null.

Returns:

A ValueResolver.UNRESOLVED is returned, the context stack will continue with the next value resolver in the chain. Otherwise, it returns the associated value.

propertySet

public java.util.Set<java.util.Map.Entry<java.lang.String,java.lang.Object>> propertySet(java.lang.Object context)

Description copied from interface: ValueResolver

List all the properties and their values for the given object.

Specified by:

propertySet in interface ValueResolver

Parameters:

context - The context object. Not null.

Returns:

All the properties and their values for the given object.
