Method Detail

checkSyntax

public ISeriesEditorSyntaxError[] checkSyntax(int iElementStart,
                                              int iElementEnd)

Syntax checks the given Element number.

Specified by:

checkSyntax in interface IISeriesEditorSyntaxChecker

Specified by:

checkSyntax in class ISeriesEditorSyntaxChecker

checkSyntax

public ISeriesEditorSyntaxError[] checkSyntax(String strLine)

Invokes the syntax checker proxy if available. The proxy is given the instance to this class. The proxy calls this instance's addSyntaxError method for each syntax error string.

checkSyntaxOfRange

public void checkSyntaxOfRange(int iElementStart,
                               int iElementEnd)

Syntax checks the specified line

Specified by:

checkSyntaxOfRange in interface IISeriesEditorSyntaxChecker

Specified by:

checkSyntaxOfRange in class ISeriesEditorSyntaxChecker

See Also:

com.ibm.etools.iseries.editor.ISeriesEditorSyntaxChecker#checkSyntaxOfRange(int, int)

isAvailable

public boolean isAvailable()

Returns whether syntax checking is available.

Specified by:

isAvailable in interface IISeriesEditorSyntaxChecker

Specified by:

isAvailable in class ISeriesEditorSyntaxChecker

isCancelable

public boolean isCancelable()

Returns whether the syntax checker is cancelable before the operation is complete.

Specified by:

isCancelable in class ISeriesEditorSyntaxChecker

getRPGSpecialCharBytes

public static byte[] getRPGSpecialCharBytes(String strSpecialChars)

This API is a workaround for RPG NL variant chars problem in syntax checker and verifier. Internal use only. Declare as public The special chars array is organized as @, $, # in ISeriesEditorParser. In some encoding, a variant char is converted to multiple bytes. For example, in Chinese GB18030, the $ special char is converted to 4 bytes. There is a bug on Syntax checker DLL and Verifier DLL right now which only takes the first 3 bytes and treat them as @, $, #. Because a variant char converts to multiple bytes, the byte for the variant char after that variant char is not used by syntax checker and verifier. Thus, this variant char will be flagged as invalid. For GB18030, both Chinese $ and # are flagged as invalid. To workaround this problem, rearrange the byte array so that it contains a complete byte for variant chars as many as possible. For example, in GB18030 case, the #'s byte and $' bytes will be switched so that #'s byte is the second element in specialchar's byte array. As a result, # will not be flagged as invalid. $ sign in GB18030 is still flagged as invalid as before.
