Unigine::Interpreter Class

Header:

#include <UnigineInterpreter.h>

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().

Methods:

Name	Description View: Sort by:
get	Returns the current interpreter pointer.
getExternClass	Returns an external user class from UnigineScript.
getExternFunction	Returns an external user function from UnigineScript.
getExternVariable	Returns an external user variable from UnigineScript.
getStack	Returns the current interpreter stack depth.
addExternClass	Adds an external user class to UnigineScript.
addExternDefine	Adds a definition to UnigineScript.
addExternFunction	Adds an external user function to UnigineScript.
addExternLibrary	Adds an external library namespace to UnigineScript.
addExternVariable	Adds an external user variable to UnigineScript.
addGroup	Adds a new group with the specified name.
error	Interpreter error function.
popStack	Pops the variable from the current interpreter stack.
removeExternClass	Remove a user class from UnigineScript.
removeExternDefine	Removes an external definition with the specified name from UnigineScript.
removeExternFunction	Removes an external user function from UnigineScript.
removeExternLibrary	Removes an external library namespace from UnigineScript.
removeExternVariable	Removes an external user variable from UnigineScript.
removeGroup	Removes all the elements (definitions, libraries, variables, functions, classes) added via addExternDefine(), addExternLibrary(), addExternVariable(), addExternFunction() and addExternClass() methods that belong to the specified group.

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.

NoticeAll 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.
