Unigine::Interpreter Class

Header:#include <UnigineInterpreter.h>

List of functions:

Unigine interpreter.

To group the elements (definitions, libraries, variables, functions, classes) together you need to create a group via addGroup(). Then, this group can be assigned as an argument to the element via the following methods:

If the same group is added to several elements, all of them can be removed from interpreter at once via removeGroup().

Interpreter Class

Members

static void * get()

Returns the current interpreter pointer.

Return value

Interpreter pointer.

static ExternClassBase * getExternClass(const char * name)

Returns an external user class from UnigineScript.

Arguments

  • const char * name - Name of the class.

Return value

Pointer to the external class.

static ExternFunctionBase * getExternFunction(const char * name)

Returns an external user function from UnigineScript.

Arguments

  • const char * name - Name of the function.

Return value

Pointer to the external function.

static ExternVariableBase * getExternVariable(const char * name)

Returns an external user variable from UnigineScript.

Arguments

  • const char * name - Name of the variable.

Return value

Pointer to the external variable.

static int getStack()

Returns the current interpreter stack depth.

Return value

Interpreter stack depth.

static void addExternClass(const char * name, ExternClassBase * extern_class, int group_id)

Adds an external user class to UnigineScript. To create an external function use MakeExternClass() command.

Arguments

  • const char * name - Name of the class.
  • ExternClassBase * extern_class - Pointer to the external class.
  • int group_id - ID of the group.

void addExternDefine(const char * name, int group_id)

Adds a definition to UnigineScript. This function is similar to #define Foo.

Arguments

  • const char * name - Name of the definition.
  • int group_id - ID of the group.

void addExternFunction(const char * name, ExternFunctionBase * extern_function, int group_id)

Adds an external user function to UnigineScript. To create an external function use addExternFunction() command.

Arguments

  • const char * name - Name of the function.
  • ExternFunctionBase * extern_function - Pointer to the external function.
  • int group_id - ID of the group.

void addExternLibrary(const char * name, int group_id)

Adds an external library namespace to UnigineScript.
Notice
All external variables and functions with names like library.function() will be treated as library functions.

Arguments

  • const char * name - Name of the library.
  • int group_id - ID of the group.

void addExternVariable(const char * name, ExternVariableBase * extern_variable, int group_id)

Adds an external user variable to UnigineScript.

Arguments

  • const char * name - Name of the variable.
  • ExternVariableBase * extern_variable - Pointer to the external variable.
  • int group_id - ID of the group.

int addGroup(const char * group_name)

Adds a new group with the specified name. This group is assigned as an argument to the element via the following methods: If the same group is added to several elements (definitions, libraries, variables, functions, classes), all of them can be removed from interpreter at once via removeGroup().

Arguments

  • const char * group_name - Name of the group.

Return value

ID of the group.

void error(const char * format)

Interpreter error function.

Arguments

  • const char * format - Format string. It is similar to the format string for printf() in C.

static Variable popStack()

Pops the variable from the current interpreter stack.

Return value

A variable.

static void removeExternClass(const char * name)

Remove a user class from UnigineScript.

Arguments

  • const char * name - Name of the class.

static void removeExternDefine(const char * name)

Removes an external definition with the specified name from UnigineScript. This function is similar to #undef Foo.

Arguments

  • const char * name - Name of the definition.

static void removeExternFunction(const char * name)

Removes an external user function from UnigineScript.

Arguments

  • const char * name - Name of the function.

static void removeExternLibrary(const char * name)

Removes an external library namespace from UnigineScript.

Arguments

  • const char * name - Name of the library.

static void removeExternVariable(const char * name)

Removes an external user variable from UnigineScript.

Arguments

  • const char * name - Name of the variable.

void removeGroup(const char * group_name)

Removes all the elements (definitions, libraries, variables, functions, classes) added via addExternDefine(), addExternLibrary(), addExternVariable(), addExternFunction() and addExternClass() methods that belong to the specified group.

Arguments

  • const char * group_name - Name of the group.
