Method Detail

redeployLengthInSeconds

float redeployLengthInSeconds()

Returns:

the average build and re-deploy length in seconds (also known as the turn-around time). Each user enters this value during the JRebel installation. If the JRebel is installed manually a length is used which is statistically average among all JRebel users.

redeployCountLast30Days

int redeployCountLast30Days()

Returns:

the number of redeploys within last 30 days.

redeployCountLast365Days

int redeployCountLast365Days()

Returns:

the number of redeploys within last 365 days.

historyLengthInDays

int historyLengthInDays()

Returns:

the length of history in days.

reportError

void reportError(Throwable e,
                 String version,
                 String jarFile)

Report CBP failure, implementation must be async.

Parameters:

e -

version -

jarFile -

reportUsedContainer

void reportUsedContainer(String name,
                         String version)

Stores information about a used container in persistent storage. This information can later be retrieved by getUsedContainers() method.

Parameters:

name - name of the container. Should be non-blank!

version - Version of the used container. May be null.

getFirstSavedRedeploy

long getFirstSavedRedeploy()

Returns:

The first redeploy ever (in javarebel.stats)

turnaroundTime

int turnaroundTime()

getTotalRedeployCount

long getTotalRedeployCount()

getRedeployCountThisHeartbeatInterval

long getRedeployCountThisHeartbeatInterval()

writeHeartbeat

void writeHeartbeat()

getUsedContainers

String[][] getUsedContainers()

Returns:

used containers. Array size should be [n][2] where n >= 0 Result[n][0] is container name (should be non-blank). Result[n][1] is container version (may be null).

clearUsedContainers

void clearUsedContainers()

Deletes information about used containers from the persistent storage.

getDailyStatistics

List<Statistics.Daily> getDailyStatistics(String sinceDate)

Returns a list of Daily statistics since the specified sinceDate, specified in ISO-8601 format (yyyy-MM-dd) up until today (excluded). If the specified sinceDate is NULL or empty, sinceDate is assumed to be "1970-01-01" Only dates where statistics were registered are returned. Statistics is registered based on the UTC timezone, and dates follow that timezone.

Parameters:

sinceDate - ISO-8601 representation OF the date (yyyy-MM-dd)

Returns:

a list of Daily statistics since the specified date (exclusive)
