Method Detail

values

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

Returns:

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

valueOf

public static InternalProperty 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

get_

private <T> T get_(Map<InternalProperty,Object> map,
         T defaultValue)

getString

public String getString(Map<InternalProperty,Object> map)

Returns the string value of this property, or null if not specified and no default.

getBoolean

public boolean getBoolean(Map<InternalProperty,Object> map)

Returns the boolean value of this property. Throws if not set and no default.

getEnum

public <E extends Enum> E getEnum(Map<InternalProperty,Object> map,
                         Class<E> enumClass)

Returns the enum value of this property. Throws if not set and no default.
