Usage

From source file:org.archive.spring.Sheet.java

/**
 * Ensure any properties targetted by this Sheet know to 
 * check the right property paths for overrides at lookup time,
 * and that the override values are compatible types for their 
 * destination properties. /*from ww  w  .j a  v  a 2  s.  c  o  m*/
 * 
 * Should be done as soon as all possible targets are 
 * constructed (ApplicationListener ContextRefreshedEvent)
 * 
 * TODO: consider if  an 'un-priming' also needs to occur to 
 * prevent confusing side-effects. 
 * TODO: consider if priming should move to another class
