isChanged

public boolean isChanged(org.babyfish.jimmer.meta.ImmutableProp prop)

从接口复制的说明: DatabaseEvent

Is the value of specified property changed.

指定者:

isChanged 在接口中 DatabaseEvent

参数:

prop - The specified property

返回:

Is the value of specified property changed

• If the current event is EntityEvent, returns whether the declaring type of specified property is assignable from the entity type of current event object and whether the value of specified property is changed.
• If the current event is AssociationEvent returns whether the specified property is AssociationEvent.getImmutableProp()

isChanged

public boolean isChanged(org.babyfish.jimmer.meta.TypedProp<?,?> prop)

从接口复制的说明: DatabaseEvent

Is the value of specified property changed

指定者:

isChanged 在接口中 DatabaseEvent

参数:

prop - The specified property

返回:

Is the value of specified property changed

• If the current event is EntityEvent, returns whether the declaring type of specified property is assignable from the entity type of current event object and whether the value of specified property is changed.
• If the current event is AssociationEvent returns whether the specified property is AssociationEvent.getImmutableProp()

getConnection

@Nullable
public @Nullable Connection getConnection()

从接口复制的说明: DatabaseEvent

Determine whether the trigger for sending the current event is within a transaction or based on binlog

• If the event is fired by binlog trigger, returns null
• If the event is fired by transaction trigger, returns current trigger

Notes, If you use jimmer in spring-boot and accept events with `@EventListener`, it will be very important to determine whether this property is null. Because once the `triggerType` of `SqlClient` is set to `BOTH`, the same event will be notified twice.

指定者:

getConnection 在接口中 DatabaseEvent

返回:

The current connection or null

getReason

@Nullable
public @Nullable Object getReason()

指定者:

getReason 在接口中 DatabaseEvent

getImmutableType

@NotNull
public @NotNull org.babyfish.jimmer.meta.ImmutableType getImmutableType()

Get the changed ref of specified property

类型参数:

T - The return type of specified property

参数:

prop - The specified property

返回:

If the value of specified property is NOT changed, return a changed ref object which is a wrapper of both old value and new value; otherwise, return null.

抛出:

IllegalArgumentException - The declaring type of specified property is not assignable from the entity type of current event object

getChangedRef

类型参数:

T - The return type of specified property

参数:

prop - The specified property

返回:

If the value of specified property is NOT changed, return a changed ref object which is a wrapper of both old value and new value; otherwise, return null.

抛出:

IllegalArgumentException - The declaring type of specified property is not assignable from the entity type of current event object

getUnchangedValue

public <T> T getUnchangedValue(org.babyfish.jimmer.meta.ImmutableProp prop)

Get the value of specified property if it is not changed.

类型参数:

T - The return type of returned property

参数:

prop - The specified property

返回:

The unchanged value of specified property

抛出:

IllegalArgumentException -

• The declaring type of specified property is not assignable from the entity type of current event object
