Class GroovyLexer

All Implemented Interfaces:
Lexer

public final class GroovyLexer extends DefaultJFlexLexer
This class is a scanner generated by JFlex 1.7.0 from the specification file src/main/jflex/jsyntaxpane/lexers/groovy.flex
  • Field Details

  • Constructor Details

    • GroovyLexer

      public GroovyLexer()
      Default constructor is needed as we will always call the yyreset
    • GroovyLexer

      public GroovyLexer(Reader in)
      Creates a new scanner
      Parameters:
      in - the java.io.Reader to read input from.
  • Method Details

    • yychar

      public int yychar()
      Description copied from class: DefaultJFlexLexer
      Return the char number from beginning of input stream. This is NOT implemented by JFLex, so the code must be added to create this and return the private yychar field
      Specified by:
      yychar in class DefaultJFlexLexer
      Returns:
    • yyclose

      public final void yyclose() throws IOException
      Closes the input stream.
      Throws:
      IOException
    • 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 ZZ_INITIAL. Internal scan buffer is resized down to its initial length, if it has grown.
      Specified by:
      yyreset in class DefaultJFlexLexer
      Parameters:
      reader - the new input stream
    • yystate

      public final int yystate()
      Returns the current lexical state.
    • yybegin

      public final void yybegin(int newState)
      Enters a new lexical state
      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 DefaultJFlexLexer
      Returns:
    • 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
      Specified by:
      yycharat in class DefaultJFlexLexer
      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.
      Specified by:
      yylength in class DefaultJFlexLexer
      Returns:
    • 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 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.
      Specified by:
      yylex in class DefaultJFlexLexer
      Returns:
      the next token
      Throws:
      IOException - if any I/O-Error occurs
