All Implemented Interfaces:

Cloneable

public class ParenOPToken
extends NestingOPToken

ParenOPToken is used to process expressions that are between "(" and ")". This can be an arithmetic expression such as (a+(b*c)+d). This class can also process the argument list to function calls such as f(a,b,c). Finally this class can process list literals such as (1,3,4,5).

Constructor Details

ParenOPToken

public ParenOPToken(String sId,
 int nBp)

Construct a new ParenOpToken with the given parameters.

Parameters:

sId - string identifier for this token

nBp - the binding power for this token

ParenOPToken

public ParenOPToken(String sId,
 int nBp,
 String sLedASTName,
 String sNudASTName)

Construct a new ParenOpToken with the given parameters.

Parameters:

sId - string representation of the token

nBp - the binding power for this token

sLedASTName - the name for this tokens AST

sNudASTName - the name for this tokens AST

Method Details

led

public Term led(OPParser p,
 Term leftNode)

Process this token and possibly the given leftNodein the context of a parser with the left denotation. A led method typically will be interested t in the token to the left. The processing results in an Abstract Syntax Tree Node that captures the meaning

Overrides:

led in class OPToken

Parameters:

p - the parser that is the context for parsing

leftNode - an ast Term that the token is possibly interested in

Returns:

an AstNode

nud

public Term nud(OPParser p)

Process this token in the context of parser p with the null denotation. A nud method typically will have no interest in the token to the left. The processing results in an Abstract Syntax Tree Node that captures the meaning

Overrides:

nud in class OPToken

Parameters:

p - the parser that is the context for parsing

Returns:

an AstNode
