Class DestructuredTarget

java.lang.Object

com.google.javascript.jscomp.DestructuredTarget

public final class DestructuredTarget
extends java.lang.Object

Represents a single target inside a destructuring pattern, whether another pattern or a lhs expression.

Call inferType to do type inference on the target lazily. This class is designed so that a caller can get information about a target, use that information to do additional type inference, and finally call inferType if desired.

createAllNonEmptyTargetsInPattern

public static com.google.common.collect.ImmutableList<DestructuredTarget> createAllNonEmptyTargetsInPattern(JSTypeRegistry registry,
                                                                                                            JSType patternType,

Returns all the targets directly in the given pattern, except for EMPTY nodes

EMPTY nodes occur in array patterns with elisions, e.g. `[, , a] = []`
