List of indexTo() Examples

Examples of indexTo()

com.persistit.Key.indexTo()
Sets the index to a specified depth. (The index is the location within the backing byte array from which the next {@link #decode} operation will decode a segment value.) Ifdepth is 0 then this method is equivalent to {@link #reset}. If depth is positive, then the index is set to point to the depthth key segment. If depth is negative, then the index is set to point to a key segment -depth segments from the end. For example, key.clear().append("a").append("b").append("c"); return key.indexTo(-1).decode(); returns "c". @param depth The depth, as defined above. @return This Key, to permit method call chaining
