Function IsDeprecatedDeclaration

internal/ast/utilities.go:1217–1219

IsDeprecatedDeclaration reports whether the given declaration is marked as @deprecated. It checks NodeFlagsPossiblyContainsDeprecatedTag on combined node flags, then confirms by walking up to find the node with the flag and performing a JSDoc lookup.

(declaration *Node)

// It checks NodeFlagsPossiblyContainsDeprecatedTag on combined node flags, then confirms
// by walking up to find the node with the flag and performing a JSDoc lookup.
func IsDeprecatedDeclaration(declaration *Node) bool {
	return IsDeprecatedDeclarationWithCachedFlags(declaration, GetCombinedNodeFlags(declaration))
}

// IsDeprecatedDeclarationWithCachedFlags is the core logic for IsDeprecatedDeclaration,
// parameterized on pre-computed combined flags so the checker can supply cached flags.
