Class CurlyToken

java.lang.Object

com.tangosol.coherence.dsltools.precedence.OPToken

com.tangosol.coherence.dsltools.precedence.NestingOPToken

com.tangosol.coherence.dsltools.termlanguage.CurlyToken

All Implemented Interfaces:

Cloneable

public class CurlyToken
extends NestingOPToken

CurlyToken is used to process expressions between bracketing characters such as are between "{" and "}" which should result in a bag such as {1,3,4,5}. It can be used as a literal or with a functor.

Constructor Detail

CurlyToken

public CurlyToken(String sId,
                  int nBp)

Construct a new CurlyToken with the given parameters.

Parameters:

sId - string identifier for this token

nBp - the binding power for this token

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

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
