Private Methods

Méthode	Description
AddError ( YAMPParseError error ) : ParseEngine	Add a parse error to the list of parse errors.
AddError ( YAMPParseError error, Block part ) : ParseEngine	Add a parse error to the list of parse errors with the block causing the error.
Advance ( ) : ParseEngine	Advances by one character.
Advance ( Int32 shift ) : ParseEngine	Advances by the specified amount of characters.
AdvanceTo ( Char target ) : ParseEngine	Advances to a specified character.
AdvanceTo ( String target ) : ParseEngine	Advances to a sequence of characters given by string.
AdvanceToNextLine ( ) : ParseEngine	Advances to the next line, i.e. the next new line character.
HasMarker ( Marker marker ) : System.Boolean
InsertMarker ( Marker marker ) : ParseEngine
ParseBlock ( Statement statement, Operator defaultOperator = null ) : Statement	Parses a block with a default operator if no operator has been found.
ParseStatement ( ) : Statement	Standard parsing of a statement (ends with ; or }).
ParseStatement ( Char termination, YAMPParseError>.Func terminationMissing = null, Func handleCharacter = null ) : Statement	More custom parsing of a statement (ends with a custom termination char).
RemoveMarker ( Marker marker ) : ParseEngine
Replace ( Int32 index, Char replacement ) : ParseEngine	Replaces a character at a specified index by the given one.
SetOffset ( Int32 line, Int32 column ) : ParseEngine	Sets an offset of the parser, i.e. sets line and column to (different) values.
SetPointer ( Int32 newPosition ) : ParseEngine	Sets the character pointer to a new position.
Skip ( ) : ParseEngine	Skips to the next significant character avoiding line comments, block comments, whitespaces or new lines.
