Method Detail

getAvailabilityZones

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

Select subnets only in the given AZs.

Default: no filtering on AZs is done

getOnePerAz

@Stability(value=Stable)
 @Nullable
default Boolean getOnePerAz()

If true, return at most one subnet per AZ.

Default: false

getSubnetFilters

@Stability(value=Stable)
 @Nullable
default List<SubnetFilter> getSubnetFilters()

List of provided subnet filters.

Default: - none

getSubnetGroupName

@Stability(value=Stable)
 @Nullable
default String getSubnetGroupName()

Select the subnet group with the given name.

Select the subnet group with the given name. This only needs to be used if you have multiple subnet groups of the same type and you need to distinguish between them. Otherwise, prefer subnetType.

This field does not select individual subnets, it selects all subnets that share the given subnet group name. This is the name supplied in subnetConfiguration.

At most one of subnetType and subnetGroupName can be supplied.

Default: - Selection by type instead of by name

getSubnetName

@Stability(value=Deprecated)
 @Deprecated
 @Nullable
default String getSubnetName()

Deprecated. Use `subnetGroupName` instead

(deprecated) Alias for `subnetGroupName`.

Select the subnet group with the given name. This only needs to be used if you have multiple subnet groups of the same type and you need to distinguish between them.

getSubnets

@Stability(value=Stable)
 @Nullable
default List<ISubnet> getSubnets()

Explicitly select individual subnets.

Use this if you don't want to automatically use all subnets in a group, but have a need to control selection down to individual subnets.

Cannot be specified together with subnetType or subnetGroupName.

Default: - Use all subnets in a selected group (all private subnets by default)

getSubnetType

@Stability(value=Stable)
 @Nullable
default SubnetType getSubnetType()

Select all subnets of the given type.

At most one of subnetType and subnetGroupName can be supplied.

Default: SubnetType.PRIVATE (or ISOLATED or PUBLIC if there are no PRIVATE subnets)

builder

@Stability(value=Stable)
static SubnetSelection.Builder builder()

Returns:

a SubnetSelection.Builder of SubnetSelection
