AttributedString

public class AttributedString
extends Object

java.lang.Object
   ↳ java.text.AttributedString

AttributedString保存文本和相关的属性信息。 在文本阅读器希望通过AttributedCharacterIterator接口访问属性文本的情况下，它可以用作实际的数据存储。

属性是由键标识的键/值对。 给定角色的两个属性不能具有相同的密钥。

属性的值是不可改变的，或者不能被客户端或存储器突变。 它们总是通过引用传递，而不是克隆。

                Map<? extends AttributedCharacterIterator.Attribute, ?> attributes)

使用给定的文本和属性构造一个AttributedString实例。

Parameters
text String: The text for this attributed string.
attributes Map: The attributes that apply to the entire string.
Throws
NullPointerException if text or attributes is null.
IllegalArgumentException if the text has length 0 and the attributes parameter is not an empty Map (attributes cannot be applied to a 0-length range).

AttributedString (AttributedCharacterIterator text)

使用由AttributedCharacterIterator表示的给定属性文本构造一个AttributedString实例。

Parameters
text AttributedCharacterIterator: The text for this attributed string.
Throws

Added in API level 1 
AttributedString (AttributedCharacterIterator text, 
                int beginIndex, 
                int endIndex)

使用由AttributedCharacterIterator表示的给定属性文本的子范围构造一个AttributedString实例。 如果给定的范围产生一个空的文本，所有的属性将被丢弃。 请注意，对于原始属性范围的子范围，将丢弃由Annotation对象包装的任何属性。

Parameters
text AttributedCharacterIterator: The text for this attributed string.
beginIndex int: Index of the first character of the range.
endIndex int: Index of the character following the last character of the range.
Throws
NullPointerException if text is null.
IllegalArgumentException if the subrange given by beginIndex and endIndex is out of the text range.

                int endIndex, 
                Attribute[] attributes)

使用由AttributedCharacterIterator表示的给定属性文本的子范围构造一个AttributedString实例。 只有符合给定属性的属性才会被合并到实例中。 如果给定的范围产生一个空的文本，所有的属性将被丢弃。 请注意，对于原始属性范围的子范围，将丢弃由Annotation对象包装的任何属性。

Parameters
text AttributedCharacterIterator: The text for this attributed string.
beginIndex int: Index of the first character of the range.
endIndex int: Index of the character following the last character of the range.
attributes Attribute: Specifies attributes to be extracted from the text. If null is specified, all available attributes will be used.
Throws

Parameters
attribute AttributedCharacterIterator.Attribute: the attribute key
value Object: the value of the attribute; may be null
