Class ActionProfileInfo

java.lang.Object
io.github.zhh2001.jp4.pipeline.ActionProfileInfo
public final class ActionProfileInfo extends Object
Read-only metadata for one P4 action profile, derived from P4Info. Construction is internal to P4Info.fromBytes(byte[]) and friends; users obtain instances through P4Info.actionProfile(String).

An action profile is the indirect-action mechanism for tables: instead of binding an action inline on every entry, a table can reference one or more pre-configured action profile members (or groups of members when withSelector() is true). The tableIds() set lists which tables share this profile.

The selector_size_semantics field added in newer P4Info revisions is intentionally not exposed in v1.4; it can be added in a future v1.x release without affecting the existing surface.

Instances are constructed once during P4Info parsing and are immutable thereafter; safe to share across threads.

Since:
1.4.0

  • Method Summary

    Modifier and Type
    Method
    Description
    int
    id()
    P4Runtime numeric id assigned by p4c.
    int
    maxGroupSize()
    Maximum weighted member entries per group; 0 when the profile does not use a selector.
    String
    name()
    Fully-qualified action-profile name, e.g.
    long
    size()
    Maximum total member entries the profile can hold; if withSelector() is true the semantics depend on the target's selector_size_semantics.
    Set<Integer>
    tableIds()
    Immutable set of table ids that share this action profile.
    String
    toString()
     
    boolean
    withSelector()
    True iff the action profile uses dynamic selection (action selector).
