Enum Constant Detail

REQUEST_RESPONSE

@Stability(value=Stable)
public static final LambdaInvocationType REQUEST_RESPONSE

Invoke the function synchronously.

Keep the connection open until the function returns a response or times out. The API response includes the function response and additional data.

EVENT

@Stability(value=Stable)
public static final LambdaInvocationType EVENT

Invoke the function asynchronously.

Send events that fail multiple times to the function's dead-letter queue (if it's configured). The API response only includes a status code.

DRY_RUN

@Stability(value=Stable)
public static final LambdaInvocationType DRY_RUN

Validate parameter values and verify that the user or role has permission to invoke the function.

Method Detail

values

public static LambdaInvocationType[] 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 (LambdaInvocationType c : LambdaInvocationType.values())
    System.out.println(c);

Returns:

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

valueOf

public static LambdaInvocationType 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
