Returns the words to highlight for UNIX shell scripts.

指定者:

getWordsToHighlight 在类中 AbstractTokenMaker

返回:

A TokenMap containing the words to highlight for UNIX shell scripts.

另请参阅:

AbstractTokenMaker.getWordsToHighlight()

getTokenList

public Token getTokenList(javax.swing.text.Segment text,
                 int startTokenType,
                 int startOffset)

Returns a list of tokens representing the given text.

参数:

text - The text to break into tokens.

startTokenType - The token with which to start tokenizing.

startOffset - The offset at which the line of tokens begins.

返回:

A linked list of tokens representing text.

addNullToken

public void addNullToken()

Adds a null token to the end of the current linked list of tokens. This should be put at the end of the linked list whenever the last token on the current line is NOT a multi-line token.

指定者:

addNullToken 在接口中 TokenMaker

addToken

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

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

指定者:

addToken 在接口中 TokenMaker

参数:

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.

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.

参数:

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.

createOccurrenceMarker

protected OccurrenceMarker createOccurrenceMarker()

Returns the occurrence marker to use for this token maker. Subclasses can override to use different implementations.

返回:

The occurrence marker to use.

getClosestStandardTokenTypeForInternalType

public int getClosestStandardTokenTypeForInternalType(int type)

Returns the closest "standard" token type for a given "internal" token type (e.g. one whose value is < 0).

The default implementation returns type always, which denotes that a mapping from internal token types to standard token types is not defined; subclasses can override.

指定者:

getClosestStandardTokenTypeForInternalType 在接口中 TokenMaker

参数:

type - The token type.

返回:

The closest "standard" token type.

getCurlyBracesDenoteCodeBlocks

public boolean getCurlyBracesDenoteCodeBlocks()

Returns whether this programming language uses curly braces ('{' and '}') to denote code blocks.

The default implementation returns false; subclasses can override this method if necessary.

指定者:

getCurlyBracesDenoteCodeBlocks 在接口中 TokenMaker

返回:

Whether curly braces denote code blocks.

getInsertBreakAction

public javax.swing.Action getInsertBreakAction()

Returns an action to handle "insert break" key presses (i.e. Enter). The default implementation returns null. Subclasses can override.

指定者:

getInsertBreakAction 在接口中 TokenMaker

返回:

The default implementation always returns null.

getLastTokenTypeOnLine

public int getLastTokenTypeOnLine(javax.swing.text.Segment text,
                         int initialTokenType)

Returns the last token on this line's type if the token is "unfinished", or TokenTypes.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 TokenTypes.COMMENT_MULTILINE for that line. This is useful for doing syntax highlighting.

指定者:

getLastTokenTypeOnLine 在接口中 TokenMaker

参数:

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).

返回:

The last token on this line's type, or TokenTypes.NULL if the line was completed.

getOccurrenceMarker

public OccurrenceMarker getOccurrenceMarker()

Returns the object in charge of marking all occurrences of the token at the current caret position, if it is a relevant token. If null is returned, a default OccurrenceMarker is used.

指定者:

getOccurrenceMarker 在接口中 TokenMaker

返回:

The occurrence marker for this language, or null for none.

getShouldIndentNextLineAfter

public boolean getShouldIndentNextLineAfter(Token token)

The default implementation returns false always. Languages that wish to better support auto-indentation can override this method.

指定者:

getShouldIndentNextLineAfter 在接口中 TokenMaker

参数:

token - The token the previous line ends with.

返回:

Whether the next line should be indented.

isMarkupLanguage

public boolean isMarkupLanguage()

The default implementation returns false always. Subclasses that are highlighting a markup language should override this method to return true.

指定者:

isMarkupLanguage 在接口中 TokenMaker

返回:

false always.

resetTokenList

protected void resetTokenList()

Deletes the linked list of tokens so we can begin anew. This should never have to be called by the programmer, as it is automatically called whenever the user calls getLastTokenTypeOnLine(Segment, int) or TokenMaker.getTokenList(Segment, int, int).

setLanguageIndex

public void setLanguageIndex(int languageIndex)

Sets the language index to assign to tokens moving forward. This property is used to designate tokens as being in "secondary" languages (such as CSS or JavaScript in HTML).

参数:

languageIndex - The new language index. A value of 0 denotes the "main" language, any positive value denotes a specific secondary language. Negative values will be treated as 0.
