Class GVTACIImpl

public class GVTACIImpl extends 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
classGVTACIImpl.TransformAttributeFilter
AttributeFilter which converts (extended) location attributes SVGAttributedCharacterIterator.TextAttribute.X, TextAttribute.Y, TextAttribute.ROTATE attributes to TextAttribute.TRANSFORM attributes.
Constructor Summary
GVTACIImpl()
Constructs a new GVTAttributedCharacterIterator with no attributes and a null string.
GVTACIImpl(AttributedCharacterIterator aci)
Constructs a GVTACIImpl whose contents are equivalent to those of aci.

Constructor Detail

GVTACIImpl

public GVTACIImpl()
Constructs a new GVTAttributedCharacterIterator with no attributes and a null string.

GVTACIImpl

public GVTACIImpl(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

clone

public Object clone()
Create a copy of this iterator

current

public char current()
Get the character at the current position (as returned by getIndex()).
Specified by: java.text.CharacterIterator.

first

public char first()
Sets the position to getBeginIndex().

Returns: the character at the start index of the text.
Specified by: java.text.CharacterIterator.

getAllAttributeKeys

public Set getAllAttributeKeys()
Get the keys of all attributes defined on the iterator's text range.

getAttribute

public Object getAttribute(Attribute attribute)
Get the value of the named attribute for the current character.

getAttributes

public Map getAttributes()
Returns a map with the attributes defined on the current character.

getBeginIndex

public int getBeginIndex()
Get the start index of the text.
Specified by: java.text.CharacterIterator.

getEndIndex

public int getEndIndex()
Get the end index of the text.
Specified by: java.text.CharacterIterator.

getIndex

public int getIndex()
Get the current index.
Specified by: java.text.CharacterIterator.

getRunLimit

public int getRunLimit()
Get the index of the first character following the run with respect to all attributes containing the current character.

getRunLimit

public int getRunLimit(Attribute attribute)
Get the index of the first character following the run with respect to the given attribute containing the current character.

getRunLimit

public int getRunLimit(Set attributes)
Get the index of the first character following the run with respect to the given attributes containing the current character.

getRunStart

public int getRunStart()
Get the index of the first character of the run with respect to all attributes containing the current character.

getRunStart

public int getRunStart(Attribute attribute)
Get the index of the first character of the run with respect to the given attribute containing the current character.

Parameters: attribute The attribute for whose appearance the first offset is requested.

getRunStart

public int getRunStart(Set attributes)
Get the index of the first character of the run with respect to the given attributes containing the current character.

Parameters: attributes the Set of attributes which begins at the returned index.

last

public char last()
Sets the position to getEndIndex()-1 (getEndIndex() if the text is empty) and returns the character at that position.
Specified by: java.text.CharacterIterator.

next

public char next()
Increments the iterator's index by one, returning the next character.

Returns: the character at the new index.
Specified by: java.text.CharacterIterator.

previous

public char previous()
Decrements the iterator's index by one and returns the character at the new index.
Specified by: java.text.CharacterIterator.

setAttributeArray

public void setAttributeArray(GVTAttributedCharacterIterator.TextAttribute attr, 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.

setIndex

public char setIndex(int position)
Sets the position to the specified position in the text.

Parameters: position The new (current) index into the text.

Returns: the character at new index position.
Specified by: java.text.CharacterIterator.

setString

public void setString(String s)
Sets this iterator's contents to an unattributed copy of String s.

setString

public void setString(AttributedString s)
Assigns this iterator's contents to be equivalent to AttributedString s.
