Misuse Details

Details about the known misuse from the MUBench dataset.

Description:	Iterator.next() is invoked without prior check of hasNext().
Fix Description:
Violation Types:	missing/condition/value_or_state
In File:	com/google/javascript/jscomp/SimpleDefinitionFinder.java
In Method:	visit(NodeTraversal, Node, Node)
Code with Misuse:	class SimpleDefinitionFinder.DefinitionGatheringCallback { @Override public void visit(NodeTraversal traversal, Node node, Node parent) { // Arguments of external functions should not count as name // definitions. They are placeholder names for documentation // purposes only which are not reachable from anywhere. if (inExterns && NodeUtil.isName(node) && parent.getType() == Token.LP) { return; } Definition def = DefinitionsRemover.getDefinition(node, inExterns); if (def != null) { String name = getSimplifiedName(def.getLValue()); if (name != null) { Node rValue = def.getRValue(); if ((rValue != null) && !NodeUtil.isImmutableValue(rValue) && !NodeUtil.isFunction(rValue)) { // Unhandled complex expression Definition unknownDef = new UnknownDefinition(def.getLValue(), inExterns); def = unknownDef; } // TODO(johnlenz) : remove this stub dropping code if it becomes // illegal to have untyped stubs in the externs definitions. if (inExterns) { // We need special handling of untyped externs stubs here: // the stub should be dropped if the name is provided elsewhere. List<Definition> stubsToRemove = Lists.newArrayList(); String qualifiedName = node.getQualifiedName(); // If there is no qualified name for this, then there will be // no stubs to remove. This will happen if node is an object // literal key. if (qualifiedName != null) { for (Definition prevDef : nameDefinitionMultimap.get(name)) { if (prevDef instanceof ExternalNameOnlyDefinition && !jsdocContainsDeclarations(node)) { String prevName = prevDef.getLValue().getQualifiedName(); if (qualifiedName.equals(prevName)) { // Drop this stub, there is a real definition. stubsToRemove.add(prevDef); } } } for (Definition prevDef : stubsToRemove) { nameDefinitionMultimap.remove(name, prevDef); } } } nameDefinitionMultimap.put(name, def); definitionSiteMap.put(node, new DefinitionSite(node, def, traversal.getModule(), traversal.inGlobalScope(), inExterns)); } } if (inExterns && (parent != null) && NodeUtil.isExpressionNode(parent)) { String name = getSimplifiedName(node); if (name != null) { // TODO(johnlenz) : remove this code if it becomes illegal to have // stubs in the externs definitions. // We need special handling of untyped externs stubs here: // the stub should be dropped if the name is provided elsewhere. // We can't just drop the stub now as it needs to be used as the // externs definition if no other definition is provided. boolean dropStub = false; if (!jsdocContainsDeclarations(node)) { String qualifiedName = node.getQualifiedName(); if (qualifiedName != null) { for (Definition prevDef : nameDefinitionMultimap.get(name)) { String prevName = prevDef.getLValue().getQualifiedName(); if (qualifiedName.equals(prevName)) { dropStub = true; break; } } } } if (!dropStub) { // Incomplete definition Definition definition = new ExternalNameOnlyDefinition(node); nameDefinitionMultimap.put(name, definition); definitionSiteMap.put(node, new DefinitionSite(node, definition, traversal.getModule(), traversal.inGlobalScope(), inExterns)); } } } } } `class SimpleDefinitionFinder.UseSiteGatheringCallback { @Override public void visit(NodeTraversal traversal, Node node, Node parent) { Collection<Definition> defs = getDefinitionsReferencedAt(node); if (defs == null) { return; } Definition first = defs.iterator().next(); String name = getSimplifiedName(first.getLValue()); Preconditions.checkNotNull(name); nameUseSiteMultimap.put( name, new UseSite(node, traversal.getModule())); } }`
