Constructor Detail

PathOPToken

public PathOPToken(String sId,
                   int nBp)

Construct a new PathOPToken with the given parameters.

Parameters:

sId - string identifier for this token

nBp - the binding power for this token

PathOPToken

public PathOPToken(String sId,
                   int nBp,
                   String sLedASTName)

Construct a new PathOPToken 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

Method Detail

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
