All Implemented Interfaces:
  java.lang.Cloneable, java.text.AttributedCharacterIterator, java.text.CharacterIterator, GVTAttributedCharacterIterator

    public class GVTACIImpl

extends java.lang.Object
implements GVTAttributedCharacterIterator

GVTACIImpl 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 GVTAttributedCharacterIterator.TextAttributes.

Nested Class Summary
`class` `GVTACIImpl.TransformAttributeFilter` AttributeFilter which converts (extended) location attributes SVGAttributedCharacterIterator.TextAttribute.X, TextAttribute.Y, TextAttribute.ROTATE attributes to TextAttribute.TRANSFORM attributes.

Constructor Detail

### GVTACIImpl

    public GVTACIImpl()

  Constructs a new GVTAttributedCharacterIterator with no attributes and a null string.

### GVTACIImpl

    public GVTACIImpl(java.text.AttributedCharacterIterator aci)

  Constructs a GVTACIImpl whose contents are equivalent to those of aci. This constructor creates a new copy of the source data in `aci`.

Method Detail

### setString

    public void setString(java.lang.String s)

  Sets this iterator's contents to an unattributed copy of String s.

  Specified by:
    `setString` in interface `GVTAttributedCharacterIterator`

### setString

    public void setString(java.text.AttributedString s)

  Assigns this iterator's contents to be equivalent to AttributedString s.

  Specified by:
    `setString` in interface `GVTAttributedCharacterIterator`

### setAttributeArray

    public void setAttributeArray(GVTAttributedCharacterIterator.TextAttribute attr,
                                  java.lang.Object[] attValues,
                                  int beginIndex,
                                  int endIndex)

  Sets values of a per-character attribute associated with the content string. Characters from `beginIndex` to `endIndex` (zero-offset) are assigned values for attribute key `attr` from the array `attValues.` If the length of attValues is less than character span `(endIndex-beginIndex)` the last value is duplicated; if attValues is longer than the character span the extra values are ignored. Note that if either beginIndex or endIndex are outside the bounds of the current character array they are clipped accordingly.

  Specified by:
