GVTAttributedCharacterIterator Used to implement SVG <tspan> and <text> attributes. This implementation is designed for efficient support of per-character attributes (i.e. single character attribute spans). It supports an extended set of TextAttributes, via inner class SVGAttributedCharacterIterator.TextAttributes.

Method Summary | |
Object |
clone()
Create a copy of this iterator |
char |
current()
Get the character at the current position (as returned by getIndex()). |
char |
first()
Sets the position to getBeginIndex(). |
Set |
getAllAttributeKeys()
Get the keys of all attributes defined on the iterator's text range. |
Object |
getAttribute(AttributedCharacterIterator.Attribute attribute)
Get the value of the named attribute for the current character. |
Map |
getAttributes()
Returns a map with the attributes defined on the current character. |
int |
getBeginIndex()
Get the start index of the text. |
int |
getEndIndex()
Get the end index of the text. |
int |
getIndex()
Get the current index. |
int |
getRunLimit()
Get the index of the first character following the run with respect to all attributes containing the current character. |
int |
getRunLimit(AttributedCharacterIterator.Attribute attribute)
Get the index of the first character following the run with respect to the given attribute containing the current character. |
int |
getRunLimit(Set attributes)
Get the index of the first character following the run with respect to the given attributes containing the current character. |
int |
getRunStart()
Get the index of the first character of the run with respect to all attributes containing the current character. |
int |
getRunStart(AttributedCharacterIterator.Attribute attribute)
Get the index of the first character of the run with respect to the given attribute containing the current character. |
int |
getRunStart(Set attributes)
Get the index of the first character of the run with respect to the given attributes containing the current character. |
char |
last()
Sets the position to getEndIndex()-1 (getEndIndex() if the text is empty) and returns the character at that position. |
char |
next()
Increments the iterator's index by one, returning the next character. |
char |
previous()
Decrements the iterator's index by one and returns the character at the new index. |
void |
setAttributeArray(GVTAttributedCharacterIterator.TextAttribute attr,
Object[] attValues,
int beginIndex,
int endIndex)
Sets values of a per-character attribute associated with the content string. |
char |
setIndex(int position)
Sets the position to the specified position in the text. |
void |
setString(AttributedString s)
Assigns this iterator's contents to be equivalent to AttributedString s. |
void |
setString(String s)
Sets this iterator's contents to an unattributed copy of String s. |
