Enum SpelMessage

java.lang.Object

java.lang.Enum<SpelMessage>

org.springframework.expression.spel.SpelMessage

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<SpelMessage>

public enum SpelMessage
extends java.lang.Enum<SpelMessage>

Contains all the messages that can be produced by the Spring Expression Language. Each message has a kind (info, warn, error) and a code number. Tests can be written to expect particular code numbers rather than particular text, enabling the message text to more easily be modified and the tests to run successfully in different locales.

When a message is formatted, it will have this kind of form

 EL1004E: (pos 34): Type cannot be found 'String'
 

The prefix captures the code and the error kind, whilst the position is included if it is known.

Since:

3.0

Method Detail

values

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

Returns:

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

valueOf

public static SpelMessage 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

formatMessage

public java.lang.String formatMessage(int pos,
                                      java.lang.Object... inserts)

Produce a complete message including the prefix, the position (if known) and with the inserts applied to the message.

Parameters:

pos - the position (ignored and not included in the message if less than 0)

inserts - the inserts to put into the formatted message

Returns:

a formatted message
