Usage

From source file:org.springframework.data.mapping.PropertyPath.java

/**
 * Tries to look up a chain of {@link PropertyPath}s by trying the givne source first. If that fails it will split the
 * source apart at camel case borders (starting from the right side) and try to look up a {@link PropertyPath} from
 * the calculated head and recombined new tail and additional tail.
 * // w  ww  .j  ava2  s  .  c o  m
