类 GraphParser

java.lang.Object

org.hibernate.graph.GraphParser

public final class GraphParser
extends Object

Parser for string representations of JPA EntityGraph (RootGraph) and Subgraph (SubGraph), using a simple syntax defined by the `graph.g` Antlr grammar.

The parse(java.lang.Class<T>, java.lang.CharSequence, javax.persistence.EntityManager) methods all create a root EntityGraph based on the passed entity class and parse the graph string into that root graph.

The parseInto(org.hibernate.graph.Graph<T>, java.lang.CharSequence, javax.persistence.EntityManager) methods parse the graph string into a passed graph, which may be a sub-graph

Multiple graphs made for the same entity type can be merged. See EntityGraphs.merge(javax.persistence.EntityManager, java.lang.Class<T>, javax.persistence.EntityGraph<T>...).

方法详细资料

parse

public static <T> RootGraph<T> parse(Class<T> rootType,

                                     javax.persistence.EntityManager entityManager)

Creates a root graph based on the passed `rootType` and parses `graphText` into the generated root graph

参数:

rootType - The root entity type

graphText - The textual representation of the graph

entityManager - The EntityManager

抛出:

InvalidGraphException - if the textual representation is invalid.

parseInto

public static <T> void parseInto(Graph<T> graph,

Parses the textual graph representation into the specified graph.

参数:

graph - The target graph. This is the graph that will be populated by this process

graphText - Textual representation of the graph

entityManager - The EntityManager

抛出:

InvalidGraphException - if the textual representation is invalid.

parseInto
