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 classorg.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 interfaceorg.fife.ui.rsyntaxtextarea.TokenMaker
- Overrides:
getLineCommentStartAndEnd
in classorg.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 fromtext
. 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 whichtext
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 classorg.fife.ui.rsyntaxtextarea.AbstractJFlexTokenMaker
- Throws:
IOException
-
yybegin
public final void yybegin(int newState)
Enters a new lexical state- Specified by:
yybegin
in classorg.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 classorg.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
