ResolveFactory( Object name, Map attributes, Object value) PreInstantiate( Object name, Map attributes, Object value) PostInstantiate( Object name, Map attributes, Object node) Returns true if references can be resolved lazily Returns the current RelationNameResolver. Public ObjectGraphBuilder.RelationNameResolver Returns the classLoader used to load a node's class. Public ObjectGraphBuilder.ChildPropertySetter Returns the current name of the 'bean' node. Inherited fields Fields inherited from classĬHILD_BUILDER, CURRENT_BUILDER, CURRENT_FACTORY, CURRENT_NAME, CURRENT_NODE, OWNER, PARENT_BUILDER, PARENT_CONTEXT, PARENT_FACTORY, PARENT_NAME, PARENT_NODE, SCRIPT_CLASS_NAME, attributeDelegates, autoRegistrationComplete, autoRegistrationRunning, explicitMethods, explicitProperties, methodMissingDelegate, postInstantiateDelegates, postNodeCompletionDelegates, preInstantiateDelegates, propertyMissingDelegate, registrationGroup, registrationGroupNameĭoCall( ObjectGraphBuilder builder, Object parent, Object node) Strategy for resolving a relationship property name. ObjectGraphBuilder.ReflectionClassNameResolverīuild objects using reflection to resolve class names.
Strategy for picking the correct synthetic reference identifier. Strategy for creating new instances of a class. Strategy for picking the correct synthetic identifier. ObjectGraphBuilder.DefaultRelationNameResolverĭefault impl that returns parentName and childName accordingly. ObjectGraphBuilder.DefaultReferenceResolver ObjectGraphBuilder.DefaultNewInstanceResolverĭefault impl that calls Class.newInstance() ObjectGraphBuilder.DefaultIdentifierResolver ObjectGraphBuilder.DefaultClassNameResolverĭefault impl that capitalizes the classname. If parent.propertyName is a Collection it will try to add child to the ObjectGraphBuilder.DefaultChildPropertySetterĭefault impl that calls parent.propertyName = child We'll also provide the choice between a directed and undirected graph, as well as a weighted/unweighted one.Strategy for setting a child node on its parent. Let's say that we have the following graph: The situation where our nodes/vertices are objects (like they most likely would be) is highly complicated and requires a lot of maintenance methods that make adjacency matrices more trouble than they're worth most of the time, so we'll only provide the implementation of the "simple" case. This rarely happens of course, but it makes explaining the adjacency matrix easier. Let's start with the assumption that we have n nodes and they're conveniently named 0,1.n-1 and that they contain the same value whose name they have. The main two approaches to this problem are adjacency matrices and adjacency lists.
#JAVA GRAPH BUILDER HOW TO#
Now that we've acquainted ourselves with what graphs are and when they're useful, we ought to know how to implement them in code. Minimum Spanning Trees - Prim's Algorithm.Graph Theory and Graph-Related Algorithm's Theory and Implementation.
#JAVA GRAPH BUILDER SERIES#
In this series we'll be taking a look at how graphs are used and represented in computer science, as well as some popular traversal algorithms: This is commonly used for finding a particular node in the graph, or for mapping out a graph. Graph traversal refers to the process of visiting nodes (aka vertices) in a graph via the connecting edges. The concept was ported from mathematics and appropriated for the needs of computer science.ĭue to the fact that many things can be represented as graphs, graph traversal has become a common task, especially used in data science and machine learning. Graphs are a convenient way to store certain types of data.
