    • getMainEntityVariable

      public String getMainEntityVariable(IdentificationVariableNode identificationVariable)

    • getMainIdentificationVariableNode

      public @Nullable IdentificationVariableNode getMainIdentificationVariableNode()

    • getMainSelectedEntityName

      public String getMainSelectedEntityName(PathNode pathNode)

    • getMainSelectedEntityVariable

      public String getMainSelectedEntityVariable(PathNode pathNode)

    • getMainSelectedPathNode

      public @Nullable PathNode getMainSelectedPathNode()

    • getParamNames

      public Set<String> getParamNames()

    • getEntityNames

      public Set<String> getEntityNames()

    • getConditions

      public List<SimpleConditionNode> getConditions()

    • getMainQueryConditions

      public List<SimpleConditionNode> getMainQueryConditions()
      Returns conditions of the main query. Conditions located in subqueries are not returned.

    • isInSubquery

      protected boolean isInSubquery(org.antlr.runtime.tree.CommonTree node)
      Returns true if the given node is located in a subquery. Subqueries are represented by the same node type as the main query, so the node is in a subquery if it has more than one query node among its parents.

    • isQueryWithJoins

      public boolean isQueryWithJoins()

    • isConditionForEntityProperty

      public boolean isConditionForEntityProperty(SimpleConditionNode condition, String variableName, String property)

    • isConditionForParameter

      public boolean isConditionForParameter(SimpleConditionNode condition, String parameterName)

    • isConditionIN

      public boolean isConditionIN(SimpleConditionNode condition)

    • isConditionISNULL

      public boolean isConditionISNULL(SimpleConditionNode condition)

    • isConditionISNOTNULL

      public boolean isConditionISNOTNULL(SimpleConditionNode condition)

    • isVariablePathNode

      public boolean isVariablePathNode(PathNode pathNode)

    • generateChildrenByClass
