List of checkExists() Examples

Examples of checkExists()

com.netflix.curator.framework.CuratorFramework.checkExists()
org.apache.curator.framework.CuratorFramework.checkExists()
Start an exists builder
The builder will return a Stat object as if org.apache.zookeeper.ZooKeeper.exists() were called. Thus, a null means that it does not exist and an actual Stat object means it does exist. @return builder object
org.quartz.Scheduler.checkExists()
Determine whether a {@link Job} with the given identifier already exists within the scheduler. @param jobKey the identifier to check for @return true if a Job exists with the given identifier @throws SchedulerException
org.tmatesoft.hg.core.HgChangesetFileSneaker.checkExists()
Shortcut to perform {@link #check(Path)} and {@link #exists()}. Result of the check may be accessed via {@link #getCheckResult()}. Errors during the check, if any, are reported through exception. @param file name of the file in question @return true if file is known at the selected changeset. @throws HgException subclass thereof to indicate specific issue with the command arguments or repository state @throws IllegalArgumentException if {@link #changeset(Nodeid)} not specified or file argument is bad.
