List of usage examples for org.apache.commons.lang ObjectUtils toString
public static String toString(Object obj, String nullStr)
Gets the toString of an Object returning a specified text if null input.
ObjectUtils.toString(null, null) = null ObjectUtils.toString(null, "null") = "null" ObjectUtils.toString("", "null") = "" ObjectUtils.toString("bat", "null") = "bat" ObjectUtils.toString(Boolean.TRUE, "null") = "true" From source file:org.amplafi.json.renderers.UriJsonRenderer.java
