Public Methods

Method	Description
EnumerateTowardsGlobal ( this scope ) : IEnumerable	Enumerates scopes from the current up to the global scope.
FindFunctionDefinitionByName ( this scope, string name, int position ) : IVariable	Locates function with a given name inside the scope. Only function definition that appear before the given position are analyzed except when scope is the global scope.
FindVariableDefinitionByName ( this scope, string name, int position ) : IVariable	Locates variable with a given name inside the scope. Only items that appear before the given position are analyzed except when scope is the global scope.
GetApplicableVariables ( this scope, int position ) : IEnumerable	Enumerates definitions of variables applicable to the given scope. Traverses scopes from the provided scope up and enumerates variables that appear at the left side of the left-hand assignment operator or at the right side of the right-hand assignment operator. Includes both regular variables as well as function definitions. Includes assignments that appear in the file up to the specified position except in the global scope it enumerates all assignments.
GetScopeVariables ( this scope, int position ) : IEnumerable	Enumerates definitions of variables applicable to the given scope. Enumerates all the variables that appear at the left side of the left assignment operator or at the right side of the right-hand assignment operator. Includes both regular variables as well as function definitions.

Method Details

EnumerateTowardsGlobal() public static method

Enumerates scopes from the current up to the global scope.

public static EnumerateTowardsGlobal ( this scope ) : IEnumerable
scope	this
return	IEnumerable

FindFunctionDefinitionByName() public static method

Locates function with a given name inside the scope. Only function definition that appear before the given position are analyzed except when scope is the global scope.

public static FindFunctionDefinitionByName ( this scope, string name, int position ) : IVariable
scope	this
name	string
position	int
return	IVariable

FindVariableDefinitionByName() public static method

Locates variable with a given name inside the scope. Only items that appear before the given position are analyzed except when scope is the global scope.

public static FindVariableDefinitionByName ( this scope, string name, int position ) : IVariable
scope	this
name	string
position	int
return	IVariable

GetApplicableVariables() public static method

Enumerates definitions of variables applicable to the given scope. Traverses scopes from the provided scope up and enumerates variables that appear at the left side of the left-hand assignment operator or at the right side of the right-hand assignment operator. Includes both regular variables as well as function definitions. Includes assignments that appear in the file up to the specified position except in the global scope it enumerates all assignments.

public static GetApplicableVariables ( this scope, int position ) : IEnumerable
scope	this
position	int
return	IEnumerable

GetScopeVariables() public static method

Enumerates definitions of variables applicable to the given scope. Enumerates all the variables that appear at the left side of the left assignment operator or at the right side of the right-hand assignment operator. Includes both regular variables as well as function definitions.

public static GetScopeVariables ( this scope, int position ) : IEnumerable
scope	this	Scope to look into
position	int	/// If scope is not a global scope, then only variables before this position /// will be enumerated. In global scope all variables are enumerated. This /// reflects how variables are visible when file is sources and user types /// somewhere in inner scope. ///
return	IEnumerable
