If a Message is reusable, downstream components should not hand over this instance to another thread, but extract its
content (via the StringBuilderFormattable#formatTo(StringBuilder) method) instead.
ReusableMessageFactory
| Modifier and Type | Method and Description |
|---|---|
| public short | Returns: the current number of parametersReturns the number of parameters that was used to initialize this reusable message for the current content. |
| public Message | Returns: an immutable snapshot of this messageReturns an immutable snapshot of the current internal state of this reusable message. |
| public Object[] | Returns: the parameter array for the current message content. This may be a vararg array of any length, or it may be a reusable array of 10 elements used to hold the unrolled vararg parameters.the parameter array that can be used for subsequent uses of this reusable message.
This replacement array must have at least 10 elements (the number of varargs supported by the Logger
API). emptyReplacement)Returns the parameter array that was used to initialize this reusable message and replaces it with the specified array. |
| getParameterCount | back to summary |
|---|---|
| public short getParameterCount() Returns the number of parameters that was used to initialize this reusable message for the current content.
The parameter array returned by

| memento | back to summary |
|---|---|
| public Message memento() Returns an immutable snapshot of the current internal state of this reusable message. The returned snapshot will not be affected by subsequent modifications of this reusable message.
| |
| swapParameters | back to summary |
|---|---|
| public Object[] swapParameters(Object[] emptyReplacement) Returns the parameter array that was used to initialize this reusable message and replaces it with the specified array. The returned parameter array will no longer be modified by this reusable message. The specified array is now "owned" by this reusable message and can be modified if necessary for the next log event. ReusableMessages that have no parameters return the specified array.
This method is used by asynchronous loggers to pass the parameter array to a background thread without
allocating new objects.
The actual number of parameters in the returned array can be determined with
