- All Superinterfaces:
- All Known Implementing Classes:
Parser's error reporter is set to an instance of this interface, then this interface's
warning(java.lang.String, java.lang.String, int, int)and
error(java.lang.String, java.lang.String, int, int)methods are called instead of the
These methods take a source char offset and a length. The rationale is that in interactive IDE-type environments, the source is available and the IDE will want to indicate where the error occurred and how much code participates in it. The start and length are generally chosen to fit within a single line, for readability, but the client is free to use the AST to determine the affected node(s) from the start position and change the error or warning's display bounds.
All Methods Instance Methods Abstract Methods Modifier and Type Method Description
error(String message, String sourceName, int offset, int length)Report an error.
warning(String message, String sourceName, int offset, int length)Report a warning.
warningReport a warning.
The implementing class may choose to ignore the warning if it desires.
Stringdescribing the warning
offset- the warning's 0-indexed char position in the input stream
length- the length of the region contributing to the warning
errorReport an error.
The implementing class is free to throw an exception if it desires.
message- a String describing the error
offset- 0-indexed char position of the error in the input stream
length- the length of the region contributing to the error
