VsFunctionCall

class VsFunctionCall : public VsExpr

Inheritance:

Public Fields
VsStatementList* statements: Statements that make up this function. Used by VsFunctionCall.

Public Methods
static void addArg(const char *argName): Again, used during parsing, adds arguments
void endDefinition(VsStatementList *stmnts): And when function is done, this cleans everything up and remembers what statements are part of this function definition:
virtual VsValue evaluate(VsFunctionCall *parent): Evaluate method.
static VsVar* findIdentifier(const char *name): Returns the local variable, argument, or global variable with the given name
VsValue getArg(int whichArg): Argument getting/setting routines, used by VsArgOrLocal class.
const char* getName(): Returns name of this function definition
int getNumArgs(): Returns number of arguments
int getNumLocals(): Returns number of local vars and args
static int isAnUnimplementedFunction(const char* fName)
void setArgOrLocal(int whichArg, const VsValue &newVal)
void setReturnValue(const VsValue &val): The enclosing VsFunctionCall is passed to all expressions and statements so that a return statement can turn around and call this:
VsFunctionDef(const char *name, VsParseTree *parent): FunctionDef constructor
virtual ~VsFunctionDef()

Protected Methods
virtual ~VsFunctionCall()

Private Fields
MbPList argOrLocalNames: Names of arguments and local vars
VsExprList args: Argument expressions
static VsFunctionDef* curFunction: When parsing, function being defined:
VsFunctionDef* function: Function definition contains statements
VsValue* locals: Arguments and local variables
char* name: This function's name
int numArgs: Number of arguments
int numLocals: Number of local variables
VsParseTree* parent: Script we're defined in
VsValue returnValue

Documentation

VsFunctionDef(const char *name, VsParseTree *parent)

FunctionDef constructor. Called during parsing; gotta keep track of current function so that we know if identifiers found inside the function are function arguments, local variables, or global variables. The VsParseTree argument is needed because global variables are kept by the ParseTree class.

static void addArg(const char *argName)

Again, used during parsing, adds arguments. It is assumed that this is called BEFORE findIdentifier() is called.

static VsVar* findIdentifier(const char *name)

Returns the local variable, argument, or global variable with the given name. A new local variable is automatically created and returned if the name isn't already known in this function.
