Class FieldAttributor

java.lang.Object
  org.jeospace.text.FieldAttributor

public class FieldAttributor

extends java.lang.Object

The field attributor maps a format StringBuffer's Fields to beginning and ending indices within the buffer. Once the format has completed, this information can then be called upon to initialize a FieldPosition object or to create an AttributedCharacterIterator.

This class is limited to only allowing a single attribute (the Field) per substring. The creation of this class was necessitated by the fact that potentially useful classes, constructors and methods within the java.text package were limited to package accessibility.

Method Detail

initialize

protected void initialize(java.lang.StringBuffer buffer)

Initialize and reset the FieldAttributor's objects to process a new formatting StringBuffer.

add

protected void add(java.text.Format.Field attr,
                   int begin,
                   int end)

Add a Field - index pair mapping

getFieldPosition

public void getFieldPosition(java.text.FieldPosition pos)

Initialize the begin and end indices of the FieldPosition object. The indices will be set to coorespond to a field within the formatted StringBuffer if the buffer contains a field specified in the FieldPosition object. Otherwise the indices are set to 0.

getIterator

public java.text.AttributedCharacterIterator getIterator()

Return the AttributedCharacterIterator for the formatted StringBuffer
