public  intgetRunStart(Attribute attribute)
     Returns the index of the first character of the run with respect to the given attribute containing the current character.
public  intgetRunStart(Set attributes)
     Returns the index of the first character of the run with respect to the given attributes containing the current character.
public  charlast()
     Sets the position to getEndIndex()-1 (getEndIndex() if the text is empty) and returns the character at that position.
public  charnext()
     Increments the iterator's index by one and returns the character at the new index.
public  charprevious()
     Decrements the iterator's index by one and returns the character at the new index.
public  charsetIndex(int position)
     Sets the position to the specified position in the text and returns that character.
Parameters:

Gets the character at the current position (as returned by getIndex()). the character at the current position or DONE if the currentposition is off the end of the text.
See Also:   MTextIterator.getIndex



first
public char first()(Code)
Sets the position to getBeginIndex() and returns the character at that position. the first character in the text, or DONE if the text is empty
See Also:   MTextIterator.getBeginIndex



getAllAttributeKeys
public Set getAllAttributeKeys()(Code)
Returns the keys of all attributes defined on the iterator's text range. The set is empty if no attributes are defined.



getAttribute
public Object getAttribute(Object attribute)(Code)
Returns the value of the named attribute for the current character. Returns null if the attribute is not defined.
Parameters:
  attribute - the key of the attribute whose value is requested.



getAttribute
public Object getAttribute(Attribute attribute)(Code)
Returns the value of the named attribute for the current character. Returns null if the attribute is not defined.
Parameters:
  attribute - the key of the attribute whose value is requested.



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



getBeginIndex
public int getBeginIndex()(Code)
Returns the start index of the text. the index at which the text begins.



getEndIndex
public int getEndIndex()(Code)
Returns the end index of the text. This index is the index of the first character following the end of the text. the index after the last character in the text



getIndex
public int getIndex()(Code)
Returns the current index. the current index.



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



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



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



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



getRunStart
