com.tangosol.coherence.dsltools.precedence.OPToken

com.tangosol.coherence.dsltools.precedence.ListOpToken

All Implemented Interfaces:

Cloneable

public class ListOpToken
extends NestingOPToken

ListOPToken is used to process expressions between bracketing characters such as are between "[" and "]" which should result in a list (e.g. [1,3,4,5]). This class does nothing to limit nesting hence nested lists are possible.

Constructor Details

ListOpToken

public ListOpToken(String sId,
 int nBp)

Construct a new InfixOPToken with the given parameters.

Parameters:

sId - string identifier for this token

nBp - the binding power for this token

ListOpToken

public ListOpToken(String sId,
 int nBp,
 String sNudASTName)

Construct a new InfixOPToken with the given parameters.

Parameters:

sId - string representation of the token

nBp - the binding power for this token

sNudASTName - 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
