| * ======== Types ======== |
| * Basic constants and types |
| * |
| * This module defines basic constants and types used throughout the |
| * `xdc.runtime` package and, in some cases, in every module. |
| * |
| * The `{@link #Common$ Common$}` structure defined by the `Types` module |
| * is available for (or common to) all modules. Every field of the |
| * `Common$` structure is a configuration parameter that may be set within |
| * a configuration script for any module (not just the |
| * `xdc.runtime` modules). The fields of this structure are typically read |
| * by the modules in the `xdc.runtime` package at configuration time to |
| * control the generation of data structures that are embedded in the |
| * application and referenced by these modules at runtime. |
| * |
| * Every module has a configuration parameter named |
| * `{@link #common$ common$}` that is of type `Common$`. This allows the user |
| * of any module to control the module's diagnostics, where its instances |
| * are allocated, how they are allocated, and (for gated modules) what |
| * gate it should use to protect critical sections. |
| * |
| * @a(Examples) |
| * Configuration example: The following configuration script specifies |
| * that the instance objects managed by the `Memory` module in the |
| * `xdc.runtime` package should be placed in the ".fast" memory section |
| * and that `ENTRY` diagnostics should be available at runtime. |
| * |
| * @p(code) |
| * var Memory = xdc.useModule('xdc.runtime.Memory"); |
| * Memory.common$.instanceSection = ".fast"; |
| * Memory.common$.diags_ENTRY = Diags.RUNTIME_OFF |
| * @p |
| * |
| * Note that by setting `Memory.common$.diags_ENTRY` to `Diags.RUNTIME_OFF` |
| * we are both enabling `ENTRY` events and specifying that they are initially |
| * disabled; they must be explicitly enabled at runtime. See the |
| * `{@link Diags}` modules for additional information. |

| * ======== ModuleId ======== |
| * Unique module identifier |
| * |
| * Module IDs are assigned at configuration time based in the set |
| * of modules that are "used" in the application. So, although each |
| * module has a unique 16-bit ID at runtime this ID may vary between |
| * configurations of the application. |
| * |
| * To save precious data space, module names are managed by the |
| * `{@link Text}` module and it is this table that is used to assign |
| * module IDs. If the table is maintained on the target, the module ID |
| * is an "index" into this table; otherwise, the module ID is simply |
| * a unique integer less than the total number of modules in the |
| * application. |
| * |
| * Although module IDs are not independent of an application's |
| * configuration, a module's ID may be compared to a runtime value |
| * symbolically. Every module has a (generated) method that returns |
| * the module's ID; e.g., a module named `Task` has a method named |
| * `Task_Module_id()` which returns `Task`'s module ID. |
| * |
| * @p(code) |
| * #include <xdc/runtime/Types.h> |
| * #include <ti/sysbios/knl/Task.h> |
| * : |
| * void checkId(Types_ModuleId modId) { |
| * if (Task_Module_id() == modId) { |
| * System_printf("Task module"); |

| * |
| * @field(diags_INTERNAL) The `{@link Diags#INTERNAL}` bit of a module's |
| * diagnostics mask. |
| * |
| * @field(diags_LIFECYCLE) The `{@link Diags#LIFECYCLE}` category of a |

| * |
| * @field(diags_STATUS) The `{@link Diags#STATUS}` category of a module's |
| * diagnostics mask. |
| * |
| * @field(diags_USER1) The `{@link Diags#USER1}` category of a module's |
| * diagnostics mask. |
| * |
| * @field(diags_USER2) The `{@link Diags#USER2}` category of a module's |
| * diagnostics mask. |
| * |
| * @field(diags_USER3) The `{@link Diags#USER3}` category of a module's |
| * diagnostics mask. |
| * |
| * @field(diags_USER4) The `{@link Diags#USER4}` category of a module's |
| * diagnostics mask. |
| * |
| * @field(diags_USER5) The `{@link Diags#USER5}` category of a module's |
| * diagnostics mask. |
| * |
| * @field(diags_USER6) The `{@link Diags#USER6}` category of a module's |
| * diagnostics mask. |
| * |
| * @field(diags_USER7) The `{@link Diags#USER7}` category of a module's |
| * diagnostics mask. The bit for this category has been repurposed for the |
| * `{@link Diags#INFO}` category, so the use of USER7 has been deprecated. |
| * |
| * @field(diags_INFO) The `{@link Diags#INFO}` category of a module's |
| * diagnostics mask. |
| * |
| * @field(diags_USER8) The `{@link Diags#USER8}` category of a module's |
| * diagnostics mask. The bit for this category has been repurposed for the |
| * `{@link Diags#ANALYSIS}` category, so the use of USER8 has been |
| * deprecated. |
| * |
| * @field(diags_ANALYSIS) The `{@link Diags#ANALYSIS}` category of a |
| * module's diagnostics mask. |
| * |
| * @field(fxntab) |
| * This configuration parameter is only applicable to modules that |
| * inherit an interface and have instance objects. Setting `fxntab` |
| * to `false` can save some data space but also prevents the |
| * application from using instance objects through abstract interfaces. |
| * |
| * Function tables are used whenever it's necessary to call a module's |
| * methods via an abstract interface; e.g., the `{@link Memory}` module |
| * calls methods defined by the `{@link IHeap}` interface but there may |
| * be several distinct modules that implement this interface. In order |
| * for this type of call to be possible, instance objects contain a |
| * reference to a function table containing the instance module's |
| * functions; the caller gets the module's function from the instance |
| * object and calls through a function pointer. Every module that |
| * inherits an interface has such a table and modules that do not |
| * inherit an interface do not have a function table. |
| * |
| * If this configuration parameter is set to `false`, the module's |
| * instance objects will NOT be initialized with a reference to their |
| * module's function table and, since the function table will not |
| * be referenced by the application, the resulting executable will be |
| * smaller. However, if this parameter is `false` you must never |
| * attempt to use this module's instance objects via reference this |
| * module through an abstract interface. Since this is often hard to |
| * determine, especially as an application evolves over time, you should |
| * only set this parameter to `false` when you are absolutely sure that |
| * the module's functions are always only being directly called and you |
| * need to absolutely minimize the data footprint of your application. |
| * |
| * The default for this parameter is `true`. |
| * |
| * @field(gate) A handle to the module-level `{@link IGateProvider}` |
| * instance to be used when this module calls functions from |
| * `{@link Gate}` |
| * |
| * @field(gateParams) `Gate` parameters used by this module to create |
| * the gates used when this module calls |
| * `{@link Gate#allocInstance() Gate_allocInstance}` |
| * |
| * @field(instanceHeap) Identifies the heap from which this module |
| * should allocate memory. |
| * |
| * @field(instanceSection) Identifies the section in which instances |
| * created by this module should be placed. |
| * |
| * @field(logger) The handle of the logger instance used by the module. |
| * All log events generated by the module are routed to this logger |
| * instance. See `{@link ILogger}` for details on the logger interface. |
| * See `{@link LoggerBuf}` and `{@link LoggerSys}` for two examples of |
| * logger modules provided by the `{@link xdc.runtime}` package. |
| * |
| * @field(memoryPolicy) Specifies whether this module should allow |
| * static object creation only (`{@link #CreatePolicy STATIC_POLICY}`), |
| * dynamic object creation but not deletion |
| * (`{@link #CreatePolicy CREATE_POLICY}`), or both dynamic object |
| * creation and deletion (`{@link #CreatePolicy DELETE_POLICY}`). |
| * |
| * @field(namedInstance) If set to `true`, each instance object is |
| * given an additional field to hold a string name that is used |
| * when displaying information about an instance. Setting this to |
| * `true` increases the size of the module's instance objects by a |
| * single word but improves the usability of tools that display |
| * instance objects. If set to `false`, assignments of instance |
| * names are silently ignored. This allows one to remove instance |
| * name support to save space without having to change any source code. |
| * See `{@link xdc.runtime.IInstance#name IInstance.name}` for details. |
| * |
| * @field(namedModule) If set to `true`, this module's string name |
| * is retained on the target so that it can be displayed as part |
| * of `{@link Log}` and `{@link Error}` events. Setting this to `false` |
| * saves data space in the application at the expense of readability |
| * of log and error messages associated with this module. |
| * |
| * Note: setting this to `false` also prevents one from controlling the |
| * module's diagnostics at runtime via `{@link Diags#setMask()}`. |
| * This method uses the module's name to lookup the module's |
| * diagnostics mask. It is still possible to control the module's |
| * diagnostics at design-time from a configuration script. |
