## Class JcrNodeTypeManager

- java.lang.Object
- - org.modeshape.jcr.JcrNodeTypeManager

- All Implemented Interfaces:
    NodeTypeManager

      @Immutable
      public class JcrNodeTypeManager
      extends Object
      implements NodeTypeManager

  Local implementation of @{link NodeTypeManager}. This class handles translation between `Name`s and `String`s based on the namespace registry from the session's execution context in order to support transient namespace remappings. All `NodeType`s returned by this implementation are wrapped with the execution context of the session to allow proper ongoing handling of names. This implies that reference equality is not a safe test for node type equivalence.

- - ### Method Detail

    - #### getAllNodeTypes

          public NodeTypeIterator getAllNodeTypes()
                                           throws RepositoryException

      Specified by:
        `getAllNodeTypes` in interface `NodeTypeManager`
      Throws:
        `RepositoryException`

    - #### getMixinNodeTypes

          public NodeTypeIterator getMixinNodeTypes()
                                             throws RepositoryException

      Specified by:
        `getMixinNodeTypes` in interface `NodeTypeManager`
      Throws:
        `RepositoryException`

    - #### getNodeType

          public org.modeshape.jcr.JcrNodeType getNodeType(String nodeTypeName)
                                                    throws NoSuchNodeTypeException,
                                                           RepositoryException

      Specified by:
        `getNodeType` in interface `NodeTypeManager`
      Throws:
        `NoSuchNodeTypeException`
        `RepositoryException`

    - #### hasNodeType

          public boolean hasNodeType(String nodeTypeName)

      Returns true if and only if the node type with the given name exists.

      This is equivalent to the following code:

           try {
               getNodeType(nodeTypeName);
               return true;
           } catch (NoSuchNodeTypeException nsnte) {
               return false;
           }

      However, the implementation is more efficient that the approach listed above and does not rely upon exceptions.
      Specified by:
        `hasNodeType` in interface `NodeTypeManager`
      Parameters:
        `nodeTypeName` - the name of the node type
      Returns:
        true if the named node type does exist, or false otherwise

        `InvalidNodeTypeDefinitionException` - if a `NodeTypeDefinition` within the `Collection` is invalid or if the `Collection` contains an object of a type other than `NodeTypeDefinition`.
        `NodeTypeExistsException` - if `allowUpdate` is `false` and a `NodeTypeDefinition` within the `Collection` specifies a node type name that is already registered.
        `UnsupportedRepositoryOperationException` - if this implementation does not support node type registration.
        `RepositoryException` - if another error occurs.

          public NodeTypeIterator registerNodeTypes(URL url,
                                           boolean allowUpdate)
                                             throws IOException,

      Description copied from interface: `NodeTypeManager`
      Registers or updates the node type definitions per the Compact Node Definition (CND) file given by the supplied URL. This method is used to register or update a set of node types with mutual dependencies. Returns an iterator over the resulting `NodeType` objects.

      The effect of the method is "all or nothing"; if an error occurs, no node types are registered or updated.

      Parameters:
        `url` - the URL that can be resolved to the file containing the node type definitions in CND format
        `allowUpdate` - a boolean stating whether existing node type definitions should be modified/updated
      Returns:
        the registered node types.
      Throws:
        `IOException` - if there is a problem reading from the supplied stream
        `InvalidNodeTypeDefinitionException` - if a `NodeTypeDefinition` within the `Collection` is invalid or if the `Collection` contains an object of a type other than `NodeTypeDefinition`.
        `NodeTypeExistsException` - if `allowUpdate` is `false` and a `NodeTypeDefinition` within the `Collection` specifies a node type name that is already registered.
        `UnsupportedRepositoryOperationException` - if this implementation does not support node type registration.
        `RepositoryException` - if another error occurs.
