| 50 | * A factory for creating {@link KeyInfo} objects from scratch or for |
| 51 | * unmarshalling a <code>KeyInfo</code> object from a corresponding XML |
| 52 | * representation. |
| 53 | * |
| 54 | * <p>Each instance of <code>KeyInfoFactory</code> supports a specific |
| 55 | * XML mechanism type. To create a <code>KeyInfoFactory</code>, call one of the |
| 56 | * static {@link #getInstance getInstance} methods, passing in the XML |
| 57 | * mechanism type desired, for example: |
| 58 | * |
| 59 | * <blockquote><code> |
| 60 | * KeyInfoFactory factory = KeyInfoFactory.getInstance("DOM"); |
| 61 | * </code></blockquote> |
| 62 | * |
| 63 | * <p>The objects that this factory produces will be based |
| 64 | * on DOM and abide by the DOM interoperability requirements as defined in the |
| 65 | * <a href="../../../../../../technotes/guides/security/xmldsig/overview.html#DOM Mechanism Requirements"> |
| 66 | * DOM Mechanism Requirements</a> section of the API overview. See the |
| 67 | * <a href="../../../../../../technotes/guides/security/xmldsig/overview.html#Service Provider"> |
| 68 | * Service Providers</a> section of the API overview for a list of standard |
| 69 | * mechanism types. |
| 70 | * |
| 71 | * <p><code>KeyInfoFactory</code> implementations are registered and loaded |
| 72 | * using the {@link java.security.Provider} mechanism. |
| 73 | * For example, a service provider that supports the |
| 74 | * DOM mechanism would be specified in the <code>Provider</code> subclass as: |
| 75 | * <pre> |
| 76 | * put("KeyInfoFactory.DOM", "org.example.DOMKeyInfoFactory"); |
| 77 | * </pre> |
| 78 | * |
| 79 | * <p>Also, the <code>XMLStructure</code>s that are created by this factory |
| 80 | * may contain state specific to the <code>KeyInfo</code> and are not |
| 81 | * intended to be reusable. |
| 82 | * |
| 83 | * <p>An implementation MUST minimally support the default mechanism type: DOM. |
| 84 | * |
| 85 | * <p>Note that a caller must use the same <code>KeyInfoFactory</code> |
| 86 | * instance to create the <code>XMLStructure</code>s of a particular |
| 87 | * <code>KeyInfo</code> object. The behavior is undefined if |
| 88 | * <code>XMLStructure</code>s from different providers or different mechanism |
| 89 | * types are used together. |
| 90 | * |
| 91 | * <p><b>Concurrent Access</b> |
| 92 | * <p>The static methods of this class are guaranteed to be thread-safe. |
| 93 | * Multiple threads may concurrently invoke the static methods defined in this |
| 94 | * class with no ill effects. |
| 95 | * |
| 96 | * <p>However, this is not true for the non-static methods defined by this |
| 97 | * class. Unless otherwise documented by a specific provider, threads that |
| 98 | * need to access a single <code>KeyInfoFactory</code> instance concurrently |
| 99 | * should synchronize amongst themselves and provide the necessary locking. |
| 100 | * Multiple threads each manipulating a different <code>KeyInfoFactory</code> |
| 101 | * instance need not synchronize. |
