Interface CfnRuleGroup.TCPFlagFieldProperty

All Superinterfaces:

software.amazon.jsii.JsiiSerializable

All Known Implementing Classes:

CfnRuleGroup.TCPFlagFieldProperty.Jsii$Proxy

Enclosing class:

CfnRuleGroup

@Stability(value=Stable)
public static interface CfnRuleGroup.TCPFlagFieldProperty
extends software.amazon.jsii.JsiiSerializable

TCP flags and masks to inspect packets for. This is used in the `RuleGroup.MatchAttributes` specification.

For example:

"TCPFlags": [ { "Flags": [ "ECE", "SYN" ], "Masks": [ "SYN", "ECE" ] } ]

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.networkfirewall.*;
 TCPFlagFieldProperty tCPFlagFieldProperty = TCPFlagFieldProperty.builder()
         .flags(List.of("flags"))
         // the properties below are optional
         .masks(List.of("masks"))
         .build();

Method Detail

getFlags

@Stability(value=Stable)
 @NotNull
List<String> getFlags()

Used in conjunction with the `Masks` setting to define the flags that must be set and flags that must not be set in order for the packet to match.

This setting can only specify values that are also specified in the Masks setting.

For the flags that are specified in the masks setting, the following must be true for the packet to match:

• The ones that are set in this flags setting must be set in the packet.
• The ones that are not set in this flags setting must also not be set in the packet.

getMasks

@Stability(value=Stable)
 @Nullable
default List<String> getMasks()

The set of flags to consider in the inspection.

To inspect all flags in the valid values list, leave this with no setting.

builder

@Stability(value=Stable)
static CfnRuleGroup.TCPFlagFieldProperty.Builder builder()

Returns:

a CfnRuleGroup.TCPFlagFieldProperty.Builder of CfnRuleGroup.TCPFlagFieldProperty
