value

public abstract String value

The index of the place holder in the message text the field provides information for.

If the index is not the same for every message text, use

• headerParamIndex()
• summaryParamIndex()
• detailsParamIndex()
• implicationsParamIndex()
• todoParamIndex()
• urlParamIndex()

to override this index.

If the index is not sufficient, because there is a certain property within the referenced entity, an OGNL (Object-Graph Navigation Language may be added to access a particular value.

Syntax

property=index:ognl-path

Example

cause=1:message

If several properties of a referenced entity are to be displayed at different indices, separate them by commas and the information for different properties separate by colons (;).

Example

cause=1:message,3:message,4:localizedMessage; message=5

Example 1

Example:

@ParentMessageParam("cause=0:message") public class
MethodAccessConfigurationException extends
PropertyAccessConfigurationException

The parent property cause provides the information for placeholder 1 by the throwable's message text.

Example 2

Example:

@ParentMessageParam(
"cause=1:message,3:message,4:localizedMessage; message=5") public class
ExampleException extends AbstractLocalizedRuntimeException

The parent property cause provides the information ( message) for placeholder 1 and 3 (just to show how the same information can be used for different placeholders), the localizedMessage provides information for placeholder 4 and the parent's message is used to supply a value for placeholder 5.
