Constructor Details

PrefixOPToken

public PrefixOPToken(String sId,
 int nBP)

Construct a new PrefixOPToken with the given parameters.

Parameters:

sId - string identifier for this token

nBP - the binding power for this token

PrefixOPToken

public PrefixOPToken(String sId,
 int nBp,
 String sASTName)

Construct a new PrefixOPToken with the given parameters.

Parameters:

sId - string representation of the token

nBp - the binding power for this token

sASTName - the name for this tokens AST

Method Details

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
