Constructor Detail

CicsLexer

public CicsLexer(LpexCharStream charStream,
                 String hostLanguage,
                 CicsLexerStyles styles,
                 CicsLexerClasses classes)

Constructor.

Parameters:

charStream - LPEX input character stream

hostLanguage - host language (e.g., LpexCommonParser.LANGUAGE_CCPP)

styles - style characters to use (predefined by the host parser)

classes - element classes to use (predefined by the host parser)

Method Detail

initialize

public void initialize()

Initializes the CICS lexer.

Specified by:

initialize in interface LpexSubparser

reinitialize

public void reinitialize()

Reinitializes the CICS lexer.

Specified by:

reinitialize in interface LpexSubparser

setTaskTags

public void setTaskTags(String[] taskTags)

Sets the comment task tags to use.

Specified by:

setTaskTags in interface ICicsLexer

processToken

public int processToken()

Retrieves and processes the next CICS token.

Specified by:

processToken in interface LpexSubparser

Returns:

LEXER_RC_OK, LEXER_RC_EOF [+LEXER_RC_MORE], LEXER_RC_END

setComment

protected void setComment(Token t)

Sets the style and element class(es) for comments. Activated by \n, \r, or * / encountered while in a comment SPECIAL_TOKEN. SPECIAL_TOKEN, rather than TOKEN, is used for these, as we don't need to see the same tokens in processToken() too, nor have them recorded in the parse.

Does the real work for the extended dummy in LpexCicsParser.jj.

Overrides:

setComment in class LpexCicsParserTokenManager

Parameters:

t - special token (token.beginLine, token.beginColumn, token.endLine, and token.endColumn identify its location: ONE-based elements and positions in the associated document view)
