类 EffectiveEntityGraph

java.lang.Object

org.hibernate.engine.spi.EffectiveEntityGraph

所有已实现的接口:

Serializable, AppliedGraph

public class EffectiveEntityGraph
extends Object
implements AppliedGraph, Serializable

Think of this as the composite modeling of a graph and the semantic. Its graph and semantic can be obtained by getGraph() and getSemantic() They can be managed by calls to applyGraph(org.hibernate.graph.spi.RootGraphImplementor<?>, org.hibernate.graph.GraphSemantic), applyConfiguredGraph(java.util.Map<java.lang.String, ?>) and clear()

从接口复制的说明: AppliedGraph

The applied graph

applyGraph

public void applyGraph(RootGraphImplementor<?> graph,
                       GraphSemantic semantic)

Apply the graph and semantic. The semantic is required. The graph may be null, but that should generally be considered mis-use.

抛出:

IllegalArgumentException - Thrown if the semantic is null

IllegalStateException - If previous state is still available (hasn't been cleared).

applyConfiguredGraph

public void applyConfiguredGraph(Map<String,?> properties)

Apply a graph and semantic based on configuration properties or hints based on GraphSemantic.getJpaHintName() for GraphSemantic.LOAD or GraphSemantic.FETCH. The semantic is required. The graph may be null, but that should generally be considered mis-use.

抛出:

IllegalArgumentException - If both kinds of graphs were present in the properties/hints

IllegalStateException - If previous state is still available (hasn't been cleared).

clear

public void clear()
