## Detailed Description

This is the main class for the compiler.

It calls the parser and processes the CST into an AST and then uses translators to translate the AST into the final resources.

## Member Function Documentation

static String Ogre::ScriptCompiler::formatErrorCode | ( | uint32 | code | ) | `[static]`

bool Ogre::ScriptCompiler::compile | ( | const String & | str,
|  | const String & | source,
|  | const String & | group |
| ) |  |  |

Takes in a string of script code and compiles it into resources.

Parameters:

  | str | The script code
  | source | The source of the script code (e.g. a script file)
  | group | The resource group to place the compiled resources into

bool Ogre::ScriptCompiler::compile | ( | const ConcreteNodeListPtr & | nodes,
|  | const String & | group |
| ) |  |  |

Compiles resources from the given concrete node list.

bool Ogre::ScriptCompiler::_compile | ( | AbstractNodeListPtr | nodes,
|  | const String & | group |
| ) |  |  |

Compiles the given abstract syntax tree.

void Ogre::ScriptCompiler::addError | ( | uint32 | code,
|  | const String & | file,
|  | int | line,
|  | const String & | msg = `""` |
| ) |  |  |

Adds the given error to the compiler's list of errors.

void Ogre::ScriptCompiler::setListener | ( | ScriptCompilerListener * | listener | ) |

Sets the listener used by the compiler.

ScriptCompilerListener* Ogre::ScriptCompiler::getListener | ( |  | ) |

Returns the currently set listener.

const String& Ogre::ScriptCompiler::getResourceGroup | ( |  | ) | const

Returns the resource group currently set for this compiler.

void Ogre::ScriptCompiler::addNameExclusion | ( | const String & | type | ) |

Adds a name exclusion to the map.

Name exclusions identify object types which cannot accept names. This means that excluded types will always have empty names. All values in the object header are stored as object values.

void Ogre::ScriptCompiler::removeNameExclusion | ( | const String & | type | ) |

Removes a name exclusion.

bool Ogre::ScriptCompiler::_fireEvent | ( | const String & | name,
|  | const std::vector< Any > & | args,
|  | Any * | retval |
| ) |  |  |

Internal method for firing the handleEvent method.

Any Ogre::ScriptCompiler::_fireCreateObject | ( | const String & | type,
|  | const std::vector< Any > & | args |
| ) |  |  |

Internal method for firing the createObject event.

AbstractNodeListPtr Ogre::ScriptCompiler::convertToAST | ( | const ConcreteNodeListPtr & | nodes | ) | `[private]`

void Ogre::ScriptCompiler::processImports | ( | AbstractNodeListPtr & | nodes | ) | `[private]`

This built-in function processes import nodes.

AbstractNodeListPtr Ogre::ScriptCompiler::loadImportPath | ( | const String & | name | ) | `[private]`

Loads the requested script and converts it to an AST.

Reimplemented in Ogre::CompositorScriptCompiler2, and Ogre::ParticleScriptCompiler.

AbstractNodeListPtr Ogre::ScriptCompiler::locateTarget | ( | AbstractNodeList * | nodes,
|  | const String & | target |

| ) |  |  | `[private]`

Handles object inheritance and variable expansion.

void Ogre::ScriptCompiler::processVariables | ( | AbstractNodeList * | nodes | ) | `[private]`

Handles processing the variables.

void Ogre::ScriptCompiler::overlayObject | ( | const AbstractNodePtr & | source,
|  | ObjectAbstractNode * | dest |
| ) |  |  | `[private]`

This function overlays the given object on the destination object following inheritance rules.

bool Ogre::ScriptCompiler::isNameExcluded | ( | const String & | cls,
|  | AbstractNode * | parent |
| ) |  |  | `[private]`

Returns true if the given class is name excluded.

void Ogre::ScriptCompiler::initWordMap | ( |  | ) | `[private]`

This function sets up the initial values in word id map.
