public class SLParenExpressionNode
extends SLExpressionNode

A SLExpressionNode that represents a parenthesized expression; it simply returns the value of the enclosed (child) expression. It is represented separately in the AST for the purpose of correct source attribution; this preserves the lexical relationship between the two parentheses and allows a tool to describe the expression as distinct from its contents.

Method Detail

executeGeneric

public Object executeGeneric(com.oracle.truffle.api.frame.VirtualFrame frame)

Description copied from class: SLExpressionNode

The execute method when no specialization is possible. This is the most general case, therefore it must be provided by all subclasses.

Specified by:

executeGeneric in class SLExpressionNode

executeLong

public long executeLong(com.oracle.truffle.api.frame.VirtualFrame frame)
                 throws com.oracle.truffle.api.nodes.UnexpectedResultException

Overrides:

executeLong in class SLExpressionNode

Throws:

com.oracle.truffle.api.nodes.UnexpectedResultException

executeBoolean

public boolean executeBoolean(com.oracle.truffle.api.frame.VirtualFrame frame)
                       throws com.oracle.truffle.api.nodes.UnexpectedResultException

Overrides:

executeBoolean in class SLExpressionNode

Throws:

com.oracle.truffle.api.nodes.UnexpectedResultException
