Class IfThenElseBuilder

java.lang.Object
  com.cloudera.cdk.morphline.stdlib.IfThenElseBuilder

All Implemented Interfaces:

CommandBuilder

public final class IfThenElseBuilder
extends Object
implements CommandBuilder

An If-Then-Else command consists of a chain of zero or more conditions commands, as well as a chain of zero or or more commands that are processed if all conditions succeed ("then commands"), as well as a chain of zero or more commands that are processed if one of the conditions fails ("else commands"). If one of the commands in the "then" chain or "else" chain fails then the entire "if" command fails (and the remaining commands in the "then" or "else" branch are skipped). Example:

         if { 
           conditions : [
 #            { fail {} }
           ]
           then : [
             { logInfo { format : "processing then..." } }
           ]
           else : [
             { logInfo { format : "processing else..." } }
           ]
         }
