Method Detail

warning

void warning(java.lang.String message,
             java.lang.String sourceName,
             int line,
             int lineOffset)

Report a warning. The implementing class may choose to ignore the warning if it desires.

Parameters:

message - a String describing the warning

sourceName - a String describing the JavaScript source where the warning occurred; typically a filename or URL

line - the line number associated with the warning

lineOffset - the offset into lineSource where problem was detected

error

void error(java.lang.String message,
           java.lang.String sourceName,
           int line,
           int lineOffset)

Report an error. The implementing class is free to throw an exception if it desires. If execution has not yet begun, the JavaScript engine is free to find additional errors rather than terminating the translation. It will not execute a script that had errors, however.

Parameters:

message - a String describing the error

sourceName - a String describing the JavaScript source where the error occurred; typically a filename or URL

line - the line number associated with the error

lineOffset - the offset into lineSource where problem was detected
