Constructor Detail

QDLSyntax

public QDLSyntax()

Constructor. This must be here because JFlex does not generate a no-parameter constructor.

QDLSyntax

public QDLSyntax(Reader in)

Creates a new scanner There is also a java.io.InputStream version of this constructor.

Parameters:

in - the java.io.Reader to read input from.

QDLSyntax

public QDLSyntax(InputStream in)

Creates a new scanner. There is also java.io.Reader version of this constructor.

Parameters:

in - the java.io.Inputstream to read input from.

Method Detail

addToken

public void addToken(char[] array,
                     int start,
                     int end,
                     int tokenType,
                     int startOffset,
                     boolean hyperlink)

Adds the token specified to the current linked list of tokens.

Overrides:

addToken in class org.fife.ui.rsyntaxtextarea.TokenMakerBase

Parameters:

array - The character array.

start - The starting offset in the array.

end - The ending offset in the array.

tokenType - The token's type.

startOffset - The offset in the document at which this token occurs.

hyperlink - Whether this token is a hyperlink.

getLineCommentStartAndEnd

public String[] getLineCommentStartAndEnd(int languageIndex)

Specified by:

getLineCommentStartAndEnd in interface org.fife.ui.rsyntaxtextarea.TokenMaker

Overrides:

getLineCommentStartAndEnd in class org.fife.ui.rsyntaxtextarea.TokenMakerBase

getTokenList

public org.fife.ui.rsyntaxtextarea.Token getTokenList(Segment text,
                                                      int initialTokenType,
                                                      int startOffset)

Returns the first token in the linked list of tokens generated from text. This method must be implemented by subclasses so they can correctly implement syntax highlighting.

Parameters:

text - The text from which to get tokens.

initialTokenType - The token type we should start with.

startOffset - The offset into the document at which text starts.

Returns:

The first Token in a linked list representing the syntax highlighted text.

yyreset

public final void yyreset(Reader reader)

Resets the scanner to read from a new input stream. Does not close the old reader. All internal variables are reset, the old input stream cannot be reused (internal buffer is discarded and lost). Lexical state is set to YY_INITIAL.

Parameters:

reader - the new input stream

yyclose

public final void yyclose()
                   throws IOException

Closes the input stream.

Specified by:

yyclose in class org.fife.ui.rsyntaxtextarea.AbstractJFlexTokenMaker

Throws:

IOException

yybegin

public final void yybegin(int newState)

Enters a new lexical state

Specified by:

yybegin in class org.fife.ui.rsyntaxtextarea.AbstractJFlexTokenMaker

Parameters:

newState - the new lexical state

yytext

public final String yytext()

Returns the text matched by the current regular expression.

Specified by:

yytext in class org.fife.ui.rsyntaxtextarea.AbstractJFlexTokenMaker

yycharat

public final char yycharat(int pos)

Returns the character at position pos from the matched text. It is equivalent to yytext().charAt(pos), but faster

Parameters:

pos - the position of the character to fetch. A value from 0 to yylength()-1.

Returns:

the character at position pos

yylength

public final int yylength()

Returns the length of the matched text region.

yypushback

public void yypushback(int number)

Pushes the specified amount of characters back into the input stream. They will be read again by then next call of the scanning method

Parameters:

number - the number of characters to be read again. This number must not be greater than yylength()!

yylex

public org.fife.ui.rsyntaxtextarea.Token yylex()
                                        throws IOException

Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.

Returns:

the next token

Throws:

IOException - if any I/O-Error occurs
