public interface: AttributedCharacterIterator [javadoc |
source]
All Implemented Interfaces:
CharacterIterator
All Known Implementing Classes:
AttributedSegment, AttributedStringIterator, AttributedStringIterator
An AttributedCharacterIterator allows iteration through both text and
related attribute information.
An attribute is a key/value pair, identified by the key. No two
attributes on a given character can have the same key.
The values for an attribute are immutable, or must not be mutated
by clients or storage. They are always passed by reference, and not
cloned.
A run with respect to an attribute is a maximum text range for
which:
- the attribute is undefined or null for the entire range, or
- the attribute value is defined and has the same non-null value for the
entire range.
A run with respect to a set of attributes is a maximum text range for
which this condition is met for each member attribute.
The returned indexes are limited to the range of the iterator.
The returned attribute information is limited to runs that contain
the current character.
Attribute keys are instances of AttributedCharacterIterator.Attribute and its
subclasses, such as java.awt.font.TextAttribute.
| Nested Class Summary: |
|---|
| public static class | AttributedCharacterIterator.Attribute | Defines attribute keys that are used to identify text attributes. These
keys are used in AttributedCharacterIterator and AttributedString. |
| Method from java.text.AttributedCharacterIterator Detail: |
public Set getAllAttributeKeys()
Returns the keys of all attributes defined on the
iterator's text range. The set is empty if no
attributes are defined. |
public Object getAttribute(AttributedCharacterIterator.Attribute attribute)
Returns the value of the named attribute for the current character.
Returns null if the attribute is not defined. |
public Map getAttributes()
Returns a map with the attributes defined on the current
character. |
public int getRunLimit()
Returns the index of the first character following the run
with respect to all attributes containing the current character. |
public int getRunLimit(AttributedCharacterIterator.Attribute attribute)
Returns the index of the first character following the run
with respect to the given attribute containing the current character. |
public int getRunLimit(Set attributes)
Returns the index of the first character following the run
with respect to the given attributes containing the current character. |
public int getRunStart()
Returns the index of the first character of the run
with respect to all attributes containing the current character. |
public int getRunStart(AttributedCharacterIterator.Attribute attribute)
Returns the index of the first character of the run
with respect to the given attribute containing the current character. |
public int getRunStart(Set attributes)
Returns the index of the first character of the run
with respect to the given attributes containing the current character. |
