BackgroundIn a project, it is found that when a checkbox is added to a tree, it is very slow to initialize it.

Cascade Cascade, only affects crud cud and does not affect reads. Do not set cascading, from a party can read one side, set up a cascade, from one side, the default can not read a lot of the party.If there is an association between two objects, whether it's a one-to-many, one-way, or two-way, if from a can be directed to B:A--->bBy default, the save of a does not
Hibernate collection mappings are often used for both "inverse" and "cascade" properties. For me, hibernate contact is not deep and the language level of all kinds of factors, found that these two properties is difficult to understand, helpless had to this two attribute interpretation work to Google and Baidu, see a lot of cow people's explanation, plus their own in the Eclipse debugging, on the " Inverse "and" ca
Because of the time, I am here to test the environment is a one-to-many relationship in the use of the annotated way of cascading, there are a lot of posts on the Internet, I have seen, but, I would like to summarize it, it felt that the cascade is unidirectional, not bidirectional, meaning that, we set two classes of the relationship between objects, Always set in one side is very specific, on the other side to set a mappedby, but if you want both si
It has been said that in the case of heap sizeWhy give a so "arbitrary" advice, not what I do with the CMS GC, but the CMS GC has always been I love a GC implementation, the reason is recommended in the case of 1, the trigger rate is not good setIn the version of JDK 1.6, the trigger ratio of the CMS GC defaults to old when used to 92%, assuming the heap size of
The domestic common CMS has dedecms, Phpcms, WordPress, Imperial cms, 5UCMS, etc., but for us, CMS or PHP is good. Different CMS focus is also different, is not easy to get started, the template is not many, the setup complex is not complex, SEO effect how, these are must be clear of the problem. Saying "the enemy can
Oracle Foreign keys only have cascade deletion and no Cascade update, but sometimes such functions may be required in the system, so the implementation process is recorded here. There are two constraints in Oracle: latency constraint and non-latency constraint. The so-called non-Delay Constraint means that when a record is changed, it will immediately check the constraints and check whether the modificati
Function: Whether the object within the annotated field is cascaded. Optional values: Javax.persistence.CascadeType.PERSIST, MERGE, REMOVE, REFRESH, DETACH, all. Choose one or more of these, and the curly braces are not available when you choose one. PERSIST The persist operation of the Cascade session. Assuming cascade = {Cascadetype.persist} is configured on the @manytomany annotation o
component of many.Cascade defines a cascade relationship between objects on both sides of a relationship, whereas inverse defines a relationship and an object's cascading relationship.Inverse is valid only for Set+one-to-many (or many-to-many), not for Many-to-one, one-to-one. Cascade is valid for relationship tokens.Inverse works on the collective object as a whole, c
Tags: style io using AR for data CTI SP on MySQL supports foreign key storage engine only InnoDB, when creating foreign keys, requires the parent table must have a corresponding index, the child table when creating foreign keys will also automatically create the corresponding index. When you create an index, you can specify the corresponding actions on the child table when the parent table is deleted, updated, including RESTRICT,NO action,SET NULL , and CASC
Personal definition: Primary prosecution: maintain one side of the joined table, usually the Creator side, which will be more efficient. Operation Principle: If inverse is set to false, one is set to true. When cascade is used to check the business status, the value one is true. I ,? Inverse acts as the party holding the set object and determines whether to control the entire set. true --- No, it is only configured in one-to-pair and allow-to-pai
We need to pay attention to the integrity of references when designing databases. During my career as a DBA, I saw many designs taking an extreme path. Before entering the detailed description of the delete cascade option, let's take a look at another option. You can set the udpate cascade option in a table with a foreign key. In my career, I have never met the need to update one or more columns with fore
First, Introduction:The AdaBoost classifier is composed of Cascade classifiers, which means that the final classifier is composed of several simple classifiers cascade. In the image detection, the inspection window through each level classifier, so that in the previous layer of detection in most of the candidate areas are excluded, all through the detection of each level of the area is the target area.Once
Stacking order and cascading context are two concepts, but they have an inseparable relationship, stacking order is very simple ^_^, serious thinking can be, and the stack context is insignificant, I just need to move the red line you understand, all said, is too simple.
