Method Summary | |

void |
addNullToken()
Adds a null token to the end of the current linked list of tokens. |
void |
addToken(char[] array,
int start,
int end,
int tokenType,
int startOffset)
Adds the token specified to the current linked list of tokens. |
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. |
void |
addToken(Segment segment,
int start,
int end,
int tokenType,
int startOffset)
Adds the token specified to the current linked list of tokens. |
abstract boolean |
getCompleteCloseTags()
Returns whether markup close tags should be completed. |
boolean |
getCurlyBracesDenoteCodeBlocks()
Returns whether this programming language uses curly braces ('{' and '}') to denote code blocks. |
Action |
getInsertBreakAction()
Returns an action to handle "insert break" key presses (i.e. |
int |
getLastTokenTypeOnLine(Segment text,
int initialTokenType)
Returns the last token on this line's type if the token is "unfinished", or Token.NULL if it was finished. |
String[] |
getLineCommentStartAndEnd()
Returns the text to place at the beginning and end of a line to "comment" it in a this programming language. |
boolean |
getMarkOccurrencesOfTokenType(int type)
Returns whether tokens of the specified type should have "mark occurrences" enabled for the current programming language. |
boolean |
getShouldIndentNextLineAfter(Token token)
The default implementation returns false always. |
boolean |
isMarkupLanguage()
Overridden to return true . |
protected void |
resetTokenList()
Deletes the linked list of tokens so we can begin anew. |
void |
setWhitespaceVisible(boolean visible,
RSyntaxTextArea textArea)
Sets whether tokens are generated that "show" whitespace. |

in interface TokenMaker
public void addToken(Segment segment, int start, int end, int tokenType, int startOffset)
segment
- Segment
to get text from.start
- Start offset in segment
of token.end
- End offset in segment
of token.tokenType
- The token's type.startOffset
- The offset in the document at which this token
occurs.public void addToken(char[] array, int start, int end, int tokenType, int startOffset)

array
- The character array from which to get the text.start
- Start offset in segment
of token.end
- End offset in segment
of token.tokenType
- The token's type.startOffset
- The offset in the document at which this token
occurs.public void addToken(char[] array, int start, int end, int tokenType, int startOffset, boolean hyperlink)
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.public boolean getCurlyBracesDenoteCodeBlocks()
The default implementation returns false
; subclasses can
override this method if necessary.
getCurlyBracesDenoteCodeBlocks
in interface TokenMaker
public Action getInsertBreakAction()
null
. Subclasses
can override.
getInsertBreakAction
in interface TokenMaker
null
.public int getLastTokenTypeOnLine(Segment text, int initialTokenType)
Token.NULL
if it was finished. For example, if C-style
syntax highlighting is being implemented, and text
contained a line of code that contained the beginning of a comment but
no end-comment marker ("*\/"), then this method would return
Token.COMMENT_MULTILINE
for that line. This is useful
for doing syntax highlighting.
getLastTokenTypeOnLine
in interface TokenMaker
text
- The line of tokens to examine.initialTokenType
- The token type to start with (i.e., the value
of getLastTokenTypeOnLine
for the line before
text
).
Token.NULL
if the line was completed.public boolean getMarkOccurrencesOfTokenType(int type)
Token.IDENTIFIER
.
Subclasses can override this method to support other token types, such
as Token.VARIABLE
.
getMarkOccurrencesOfTokenType
in interface TokenMaker
type
- The token type.
public boolean getShouldIndentNextLineAfter(Token token)
false
always. Languages
that wish to better support auto-indentation can override this method.
getShouldIndentNextLineAfter
in interface TokenMaker
token
- The token the previous line ends with.
protected void resetTokenList()
getLastTokenTypeOnLine(Segment, int)
or
TokenMaker.getTokenList(Segment, int, int)
.
public void setWhitespaceVisible(boolean visible, RSyntaxTextArea textArea)
setWhitespaceVisible
in interface TokenMaker
visible
- Whether whitespace should be visible.
