Constructor Details

DefaultMessageSourceResolvable

public DefaultMessageSourceResolvable(String code)

Create a new DefaultMessageSourceResolvable.

Parameters:

code - the code to be used to resolve this message

DefaultMessageSourceResolvable

public DefaultMessageSourceResolvable(String[] codes)

Create a new DefaultMessageSourceResolvable.

Parameters:

codes - the codes to be used to resolve this message

DefaultMessageSourceResolvable

public DefaultMessageSourceResolvable(String[] codes,
 String defaultMessage)

Create a new DefaultMessageSourceResolvable.

Parameters:

codes - the codes to be used to resolve this message

defaultMessage - the default message to be used to resolve this message

DefaultMessageSourceResolvable

public DefaultMessageSourceResolvable(String[] codes,
 Object[] arguments)

Create a new DefaultMessageSourceResolvable.

Parameters:

codes - the codes to be used to resolve this message

arguments - the array of arguments to be used to resolve this message

DefaultMessageSourceResolvable

public DefaultMessageSourceResolvable(@Nullable
 String[] codes,
 @Nullable
 Object[] arguments,
 @Nullable
 String defaultMessage)

Create a new DefaultMessageSourceResolvable.

Parameters:

codes - the codes to be used to resolve this message

arguments - the array of arguments to be used to resolve this message

defaultMessage - the default message to be used to resolve this message

DefaultMessageSourceResolvable

public DefaultMessageSourceResolvable(MessageSourceResolvable resolvable)

Copy constructor: Create a new instance from another resolvable.

Parameters:

resolvable - the resolvable to copy from

Method Details

getCode

@Nullable
public String getCode()

Return the default code of this resolvable, that is, the last one in the codes array.

getCodes

@Nullable
public String[] getCodes()

Description copied from interface: MessageSourceResolvable

Return the codes to be used to resolve this message, in the order that they should get tried. The last code will therefore be the default one.

Specified by:

getCodes in interface MessageSourceResolvable

Returns:

a String array of codes which are associated with this message

getArguments

@Nullable
public Object[] getArguments()

Description copied from interface: MessageSourceResolvable

Return the array of arguments to be used to resolve this message.

The default implementation simply returns null.

Specified by:

getArguments in interface MessageSourceResolvable

Returns:

an array of objects to be used as parameters to replace placeholders within the message text

See Also:

• MessageFormat

getDefaultMessage

@Nullable
public String getDefaultMessage()

Description copied from interface: MessageSourceResolvable

Return the default message to be used to resolve this message.

The default implementation simply returns null. Note that the default message may be identical to the primary message code (MessageSourceResolvable.getCodes()), which effectively enforces AbstractMessageSource.setUseCodeAsDefaultMessage(boolean) for this particular message.

Specified by:

getDefaultMessage in interface MessageSourceResolvable

Returns:

the default message, or null if no default

shouldRenderDefaultMessage

public boolean shouldRenderDefaultMessage()

Indicate whether the specified default message needs to be rendered for substituting placeholders and/or MessageFormat escaping.

Returns:

true if the default message may contain argument placeholders; false if it definitely does not contain placeholders or custom escaping and can therefore be simply exposed as-is

5.1.7

resolvableToString

protected final String resolvableToString()

Build a default String representation for this MessageSourceResolvable: including codes, arguments, and default message.

toString

public String toString()

The default implementation exposes the attributes of this MessageSourceResolvable.

To be overridden in more specific subclasses, potentially including the resolvable content through resolvableToString().

Overrides:

toString in class Object

equals

public boolean equals(@Nullable
 Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
