Constructor Detail

LiteralOPToken

public LiteralOPToken(LiteralBaseToken bt)

Construct a new LiteralOPToken with the given parameters.

Parameters:

bt - the LiteralBaseToken that holds the literal info

LiteralOPToken

public LiteralOPToken(String s,
                      int nTypeCode,
                      String sNudASTName)

Construct a new LiteralOPToken with the given parameters.

Parameters:

s - string representation of the literal

nTypeCode - the type code for this literal token

sNudASTName - the name to use for building an AST

LiteralOPToken

public LiteralOPToken(String s,
                      int nTypeCode)

Construct a new LiteralOPToken with the given parameters.

Parameters:

s - string representation of the literal

nTypeCode - the type code for this literal token

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

toString

public String toString()

Return a human-readable description for this token.

Overrides:

toString in class OPToken

Returns:

a String description of the token
