openComment

boolean openComment

true if an open "/*" was found on this line

a

char[] a

start

int start

stop

int stop

keywords

static java.lang.String[] keywords

kSize

static int kSize

keys

static char[][][] keys

Stores vectors alphabetically ordered. Each of these vectors contains all the keywords that start with the same letter. There should be no more than 30 sorts of starting characters and 15 keywords starting with the same letter.

keysLengths

static int[] keysLengths

How many keys are into each vector.

keyBuffer1

char[][] keyBuffer1

keyBuffer2

char[][] keyBuffer2

c

int c

The pointer inside the current segment

Constructor Detail

VerilogScanner

VerilogScanner()

Method Detail

static void ()

init

final void init(javax.swing.text.Segment s)

noMoreTokens

final boolean noMoreTokens()

no more tears !

getToken

final boolean getToken()

debug

void debug(java.lang.String s)

matchKeyword

void matchKeyword()

Checks whether there is a kwyword starting at tha current point or not and sets the tokType accordingly. The c pointer is advanced to the first unmatched character.

scanCommentEnd

boolean scanCommentEnd()

Returns:

true if the multiline comment ends on this line

isKeywordConstituent

static final boolean isKeywordConstituent(char c)

We could use isAlpha, but as u see from the keyword table, there appear only lower case words an tha characters '0' ad '1', so we can shrink the number of tests.

isAlpha

static final boolean isAlpha(char c)

isAlpha1

static final boolean isAlpha1(char c)

isDigit

static final boolean isDigit(char c)

main

public static void main(java.lang.String[] args)
