方法详细资料

getImmutableProp

@NotNull
public @NotNull org.babyfish.jimmer.meta.ImmutableProp getImmutableProp()

getSourceId

@NotNull
public @NotNull Object getSourceId()

getDetachedTargetId

@Nullable
public @Nullable Object getDetachedTargetId()

getAttachedTargetId

@Nullable
public @Nullable Object getAttachedTargetId()

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 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 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

getType

@NotNull
public @NotNull AssociationEvent.Type getType()

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

equals

public boolean equals(Object o)

覆盖:

equals 在类中 Object

toString

public String toString()

覆盖:

toString 在类中 Object
