Public Methods

Method Description
CreateMethod ( VList methodBody ) : LNode

Creates the default method definition to wrap around the body of the rule, which has already been generated. Returns Basis with the specified new method body. If Basis is null, a simple default method signature is used, e.g. public void R() {...} where R is the rule name.
GetMethodSignature ( ) : LNode

Returns Basis if it's a method signature; otherwise constructs a default signature.

Method Details

CreateMethod() public method

Creates the default method definition to wrap around the body of the rule, which has already been generated. Returns Basis with the specified new method body. If Basis is null, a simple default method signature is used, e.g. public void R() {...} where R is the rule name.
public CreateMethod ( VList methodBody ) : LNode
methodBody VList The parsing code that was generated for this rule.
return LNode

GetMethodSignature() public method

Returns Basis if it's a method signature; otherwise constructs a default signature.
public GetMethodSignature ( ) : LNode
return LNode

Property Details

Basis public_oe property

A node that contains the original code of the rule, or, if the rule was created programmatically, the method prototype (e.g. #fn(int, Rule, #(#var(int, arg))), which means int Rule(int arg)). This can be null, in which case the default prototype is void Rule();, or if the rule is a starting rule or token, public void Rule();.
The Basis is also used to provide an error location.
