TokenImpl

java.lang.Object
- com.fr.design.gui.syntax.ui.rsyntaxtextarea.TokenImpl

所有已实现的接口:

Token, TokenTypes
```
public class TokenImpl
extends java.lang.Object
implements Token
```
The default implementation of Token.
Note: The instances of Token returned by RSyntaxDocuments are pooled and should always be treated as immutable. They should not be cast to TokenImpl and modified. Modifying tokens you did not create yourself can and will result in rendering issues and/or runtime exceptions. You have been warned!

```
    从接口复制的说明: Token
    
    Determines the offset into this token list (i.e., into the document) that covers pixel location x if the token list starts at pixel location x0
    . This method will return the document position "closest" to the x-coordinate (i.e., if they click on the "right-half" of the w in awe, the caret will be placed in between the w and e; similarly, clicking on the left-half places the caret between the a and w). This makes it useful for methods such as viewToModel found in javax.swing.text.View subclasses.
    
    指定者:
    
    getListOffset 在接口中 Token
    
    参数:
    textArea - The text area from which the token list was derived.
    e - How to expand tabs.

                   float endBeforeX)
```
    从接口复制的说明: Token
    
    Returns the position in the document that represents the last character in the token that will fit into endBeforeX-startX pixels. For example, if you're using a monospaced 8-pixel-per-character font, have the token "while" and startX is 0 and endBeforeX is 30, this method will return the document position of the "i" in "while", because the "i" ends at pixel 24, while the "l" ends at 32. If not even the first character fits in endBeforeX-startX, the first character's position is still returned so calling methods don't go into infinite loops.
    
    指定者:
    
    getOffsetBeforeX 在接口中 Token
    
    参数:
    textArea - The text area in which this token is being painted.

    endBeforeX - The x-coordinate for which you want to find the last character of t which comes before it.
    
    返回:
    The last document position that will fit in the specified amount of pixels.
  - getTextArray

```
    Returns the position in the document corresponding to the specified position in this token's internal char array (textOffset - textOffset+textCount-1).
    Note that this method does NOT do any bounds checking; you can pass in an invalid token position, and you will not receive an Exception or any other indication that the returned document position is invalid. It is up to the user to ensure valid input.
    
    指定者:
    
    tokenToDocument 在接口中 Token
