Enum SurroundingTransactionDetectorMethodInterceptor

java.lang.Object

java.lang.Enum<SurroundingTransactionDetectorMethodInterceptor>

org.springframework.data.repository.core.support.SurroundingTransactionDetectorMethodInterceptor

All Implemented Interfaces:

Serializable, Comparable<SurroundingTransactionDetectorMethodInterceptor>, Advice, Interceptor, MethodInterceptor

public enum SurroundingTransactionDetectorMethodInterceptor
extends Enum<SurroundingTransactionDetectorMethodInterceptor>
implements MethodInterceptor

MethodInterceptor detecting whether a transaction is already running and exposing that fact via isSurroundingTransactionActive(). Useful in case subsequent interceptors might create transactions themselves but downstream components have to find out whether there was one running before the call entered the proxy.

Method Detail

values

public static SurroundingTransactionDetectorMethodInterceptor[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SurroundingTransactionDetectorMethodInterceptor c : SurroundingTransactionDetectorMethodInterceptor.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SurroundingTransactionDetectorMethodInterceptor valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
