Constructor Detail

KeywordOPToken

public KeywordOPToken(String s)

Construct a new KeywordOPToken with the given parameters.

Parameters:

s - string value of the identifier

Method Detail

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

led

public Term led(OPParser parser,
                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:

parser - the parser that is the context for parsing

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

Returns:

an AstNode
