The ParseType abstract base class for parsing one "type" of Nodes.

This superclass allows each Node to be parsed by different ParseTypes that all fall under the same inherited superclass. It would have been difficult for each node to parse itself (redundant code for operators,etc), and it also would have been difficult and poor design to make the Parser responsible for each type of input. Thus, the Parser subordinates the task of parsing to the ParseTypes contained in the Language class. Each ParseType is responsible for parsing an whole group of Nodes, and each Node subclass should have a ParseType defined for it.

IsMyType	method	public	Tests whether or not the next object to be parsed can be handled by this ParseType.

ParseOne	method	public	Parses the next object in the input string if possible.

Code:

public ParseType (

const ParseType & )

Tests whether or not the next object to be parsed can be handled by this ParseType.

This function allows the Language and the Parser class to subordinate the task of parsing an input string. Because each ParseType can recognize and parse itself, the code is very extendable and more object oriented.

Code:

public virtual bool IsMyType (

ParseData & myData ) const = 0

automatically generated

Source:

parsetype.hh

Code:

public ParseType & operator = (

const ParseType & )

Parses the next object in the input string if possible.

Like IsMyType(), this allows subordinator because the ParseType is able to perform its own parsing when given the ParseData.
