function _node_types_build

Builds and returns the list of available node types.

This function reads from disk individual config files that define the available content types in the system. Modules may bundle a content type with their module by including a "node.type.[type_name].json" config file in their module's config directory. Each file should contain:

• name: (required) The human-readable name of the node type.
• base: (required) The base string used to construct callbacks corresponding to this node type (for example, if base is defined as example_foo, then example_foo_insert will be called when inserting a node of that type). This string is usually the name of the module, but not always.
• description: (required) A brief description of the node type.
• help: (optional) Help information shown to the user when creating a node of this type.
• has_title: (optional) A Boolean indicating whether or not this node type has a title field.
• title_label: (optional) The label for the title field of this content type.
• locked: (optional) A Boolean indicating whether the administrator can change the machine name of this type. FALSE = changeable (not locked), TRUE = unchangeable (locked).

Return value

An object with two properties::

• names: Associative array of the names of node types, keyed by the type.
• types: Associative array of node type objects, keyed by the type.

These arrays will also include obsolete types: types that were previously defined by modules that have been disabled, likely by a module that was provided a node type and then was disabled. These are indicated in the type object by $type->disabled being set to TRUE.
