Usage

From source file:com.codelanx.codelanxlib.config.Config.java

/**
 * Attempts to return the {@link Config} value as a casted type. If the
 * value cannot be casted it will attempt to return the default value. If
 * the default value is inappropriate for the class, the method will
 * throw a {@link ClassCastException}. This exception is also throwing if
 * the type used for the members contained within the collection are
 * incorrect/*from  ww  w  .  ja  v a2 s .  c  om*/
 * 
 * @since 0.1.0
 * @version 0.1.0
 * 
 * @param <T> The type of the casting class
 * @param <G> The type of the collection's contents
 * @param collection The collection type to cast to
 * @param type The generic bounding for the collection
 * @return A casted value, or {@code null} if unable to cast. If the passed
 *         class parameter is of a primitive type or autoboxed primitive,
 *         then a casted value of -1 is returned, or {@code false} for
 *         booleans. If the passed class parameter is for {@link String},
 *         then {@link Object#toString()} is called on the value instead
