AttributedCharacterIterator

interface AttributedCharacterIterator : CharacterIterator
java.text.AttributedCharacterIterator

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.

When getting a run with no explicit attributes specified (i.e., calling getRunStart() and getRunLimit()), any contiguous text segments having the same attributes (the same set of attribute/value pairs) are treated as separate runs if the attributes have been given to those text segments separately.

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.

Public methods

getAllAttributeKeys

Added in API level 1
abstract fun getAllAttributeKeys(): MutableSet<AttributedCharacterIterator.Attribute!>!

Returns the keys of all attributes defined on the iterator's text range. The set is empty if no attributes are defined.

Return
MutableSet<AttributedCharacterIterator.Attribute!>! the keys of all attributes

getAttribute

Added in API level 1
abstract fun getAttribute(attribute: AttributedCharacterIterator.Attribute!): Any!

Returns the value of the named attribute for the current character. Returns null if the attribute is not defined.

Parameters
attribute AttributedCharacterIterator.Attribute!: the desired attribute
Return
Any! the value of the named attribute or null

getAttributes

Added in API level 1
abstract fun getAttributes(): MutableMap<AttributedCharacterIterator.Attribute!, Any!>!

Returns a map with the attributes defined on the current character.

Return
MutableMap<AttributedCharacterIterator.Attribute!, Any!>! a map with the attributes defined on the current character

getRunLimit

Added in API level 1
abstract fun getRunLimit(): Int

Returns the index of the first character following the run with respect to all attributes containing the current character.

Any contiguous text segments having the same attributes (the same set of attribute/value pairs) are treated as separate runs if the attributes have been given to those text segments separately.

Return
Int the index of the first character following the run

getRunLimit

Added in API level 1
abstract fun getRunLimit(attribute: AttributedCharacterIterator.Attribute!): Int

Returns the index of the first character following the run with respect to the given attribute containing the current character.

Parameters
attribute AttributedCharacterIterator.Attribute!: the desired attribute
Return
Int the index of the first character following the run

getRunLimit

Added in API level 1
abstract fun getRunLimit(attributes: MutableSet<out AttributedCharacterIterator.Attribute!>!): Int

Returns the index of the first character following the run with respect to the given attributes containing the current character.

Parameters
attributes MutableSet<out AttributedCharacterIterator.Attribute!>!: a set of the desired attributes
Return
Int the index of the first character following the run

getRunStart

Added in API level 1
abstract fun getRunStart(): Int

Returns the index of the first character of the run with respect to all attributes containing the current character.

Any contiguous text segments having the same attributes (the same set of attribute/value pairs) are treated as separate runs if the attributes have been given to those text segments separately.

Return
Int the index of the first character of the run

getRunStart

Added in API level 1
abstract fun getRunStart(attribute: AttributedCharacterIterator.Attribute!): Int

Returns the index of the first character of the run with respect to the given attribute containing the current character.

Parameters
attribute AttributedCharacterIterator.Attribute!: the desired attribute.
Return
Int the index of the first character of the run

getRunStart

Added in API level 1
abstract fun getRunStart(attributes: MutableSet<out AttributedCharacterIterator.Attribute!>!): Int

Returns the index of the first character of the run with respect to the given attributes containing the current character.

Parameters
attributes MutableSet<out AttributedCharacterIterator.Attribute!>!: a set of the desired attributes.
Return
Int the index of the first character of the run
