Examples of org.jamesii.core.parameters.ParameterBlock

org.jamesii.core.parameters.ParameterBlock
A parameter block. This is the central class for handling algorithm parameters. It is nested with sub-block of the same type, each of which is associated with a name (that has to be unique for the given parent block). Think of it as a tree with edge labels, and the edges of a parent to its child nodes all have to have distinct labels (names). The value of a parameter block can be any {@link Object}, but for distributed setups and storage it will be necessary to assign {@link Serializable} values only.Several get... methods have a static analogue in {@link ParameterBlocks} thattakes an additional {@link ParameterBlock} argument and is null-safe, i.e.returns something (usually null) if the block itself is null instead of throwing an exception. @author Jan Himmelspach @author Roland Ewald @see ParameterBlocks
