Constructor Details

RemoteInvocationResult

public RemoteInvocationResult(@Nullable
 Object value)

Create a new RemoteInvocationResult for the given result value.

Parameters:

value - the result value returned by a successful invocation of the target method

RemoteInvocationResult

public RemoteInvocationResult(@Nullable
 Throwable exception)

Create a new RemoteInvocationResult for the given exception.

Parameters:

exception - the exception thrown by an unsuccessful invocation of the target method

RemoteInvocationResult

public RemoteInvocationResult()

Create a new RemoteInvocationResult for JavaBean-style deserialization (e.g. with Jackson).

• setException(java.lang.Throwable)

Method Details

setValue

public void setValue(@Nullable
 Object value)

Set the result value returned by a successful invocation of the target method, if any.

This setter is intended for JavaBean-style deserialization. Use RemoteInvocationResult(Object) otherwise.

See Also:

• RemoteInvocationResult()

getValue

@Nullable
public Object getValue()

Return the result value returned by a successful invocation of the target method, if any.

See Also:

• hasException()

setException

public void setException(@Nullable
 Throwable exception)

Set the exception thrown by an unsuccessful invocation of the target method, if any.

This setter is intended for JavaBean-style deserialization. Use RemoteInvocationResult(Throwable) otherwise.

See Also:

• RemoteInvocationResult()

getException

@Nullable
public Throwable getException()

Return the exception thrown by an unsuccessful invocation of the target method, if any.

See Also:

• hasException()

hasException

public boolean hasException()

Return whether this invocation result holds an exception. If this returns false, the result value applies (even if it is null).

See Also:

• getValue()
• getException()

hasInvocationTargetException

public boolean hasInvocationTargetException()

Return whether this invocation result holds an InvocationTargetException, thrown by an invocation of the target method itself.

See Also:

• hasException()

recreate

@Nullable
public Object recreate()
                throws Throwable

Recreate the invocation result, either returning the result value in case of a successful invocation of the target method, or rethrowing the exception thrown by the target method.

Returns:

the result value, if any

Throws:

Throwable - the exception, if any
