示例1: continueStatement

/**
* ContinueStatement :
* continue Identifier? ; // [no LineTerminator here]
*
* See 12.7
*
* Parse CONTINUE statement.
*/

// Capture CONTINUE token.
final int continueLine = line;
final long continueToken = token;
// CONTINUE tested in caller.
nextOrEOL();
LabelNode labelNode = null;
// SEMICOLON or label.
switch (type) {
case RBRACE:
case SEMICOLON:
case EOL:
case EOF:

}
示例2: breakStatement
