IF_Trigger.PostActionContext ​

Class

apex
global class IF_Trigger.PostActionContext

Context handed to a post-trigger action when the dispatcher unwinds the outermost trigger dispatch. Carries the set of SObject types whose triggers participated in the transaction so the post-action can branch on which objects were touched without re-querying. The framework constructs and supplies this object — subscribers should not need to construct it directly outside of unit tests. Why Set<SObjectType> rather than record IDs: the post-action runs once per outermost dispatch with no per-record context, so the type-level discriminator is what's load-bearing. Per-record IDs would (1) carry an unbounded heap cost in batch contexts, (2) leak record material across post-actions written by different teams in the same org. Subscribers needing per-record context should maintain their own domain-specific statics during their trigger actions and consult them inside the post-action.

Example:

apex
// Inside a PostAction.execute(context):
if(context.touchedSObjectTypes.contains(Account.SObjectType))
{
    // Account triggers participated; run Account-domain work.
}

MethodDescription
global PostActionContext(Set<SObjectType> touched)Constructs a post-action context with the supplied set of touched SObject types.

Property Details ​

touchedSObjectTypes ​

apex
global Set<SObjectType> touchedSObjectTypes

Type: Set

The SObject types whose triggers participated in the transaction. The framework stores a defensive copy on construction and the setter is private, so the framework's own source set cannot be mutated through this reference; subscribers must still treat the returned Set as read-only — a single context instance is shared across every post-action in the dispatch, so mutating it has no defined effect and could affect other post-actions. An empty set is possible — a post-action that ran solely because of a bypassed-but-still-fired trigger could see an empty context. Subscribers should null-check defensively even though the constructor guarantees a non-null Set.

Method Details ​

PostActionContext ​

apex
global PostActionContext(Set<SObjectType> touched)

Constructs a post-action context with the supplied set of touched SObject types. A null argument is normalised to an empty Set so subscribers can safely call .contains(...) without null-checking. Intended for framework and unit-test construction; subscribers receive instances via PostAction.execute.

Parameters:

  • touched (Set) - The set of SObject types whose triggers participated, or null.
