    public class PresentationTextObject

extends AbstractNamedAFPObject

The Presentation Text object is the data object used in document processing environments for representing text which has been prepared for presentation. Text, as used here, means an ordered string of characters, such as graphic symbols, numbers, and letters, that are suitable for the specific purpose of representing coherent information. Text which has been prepared for presentation has been reduced to a primitive form through explicit specification of the characters and their placement in the presentation space. Control sequences which designate specific control functions may be embedded within the text. These functions extend the primitive form by applying specific characteristics to the text when it is presented. The collection of the graphic characters and control codes is called Presentation Text, and the object that contains the Presentation Text is called the PresentationText object.

The content for this object can be created using `PtocaBuilder`.

Constructor Detail

### PresentationTextObject

    public PresentationTextObject(java.lang.String name)

  Construct a new PresentationTextObject for the specified name argument, the name should be an 8 character identifier.

  Parameters:
    `name` - the name of this presentation object

Method Detail

### createTextData

    public void createTextData(AFPTextDataInfo textDataInfo)
                        throws java.io.UnsupportedEncodingException

  Create the presentation text data for the byte array of data.

  Parameters:
    `textDataInfo` - The afp text data
  Throws:
    `java.io.UnsupportedEncodingException` - thrown if character encoding is not supported

### createControlSequences

    public void createControlSequences(PtocaProducer producer)
                                throws java.io.UnsupportedEncodingException

  Creates a chain of control sequences using a producer.

  Parameters:
    `producer` - the producer
  Throws:
    `java.io.UnsupportedEncodingException` - thrown if character encoding is not supported

### createLineData

    public void createLineData(AFPLineDataInfo lineDataInfo)

  Drawing of lines using the starting and ending coordinates, thickness and orientation arguments.

  Parameters:
    `lineDataInfo` - the line data information.

### writeStart

    protected void writeStart(java.io.OutputStream os)
                       throws java.io.IOException

  Helper method to write the start of the Object.

  Overrides:
    `writeStart` in class `AbstractStructuredObject`
  Parameters:
    `os` - The stream to write to
  Throws:
    `java.io.IOException` - throws an I/O exception if one occurred

### writeContent

    protected void writeContent(java.io.OutputStream os)
                         throws java.io.IOException

  Helper method to write the contents of the Object.

  Overrides:
    `writeContent` in class `AbstractStructuredObject`
  Parameters:
    `os` - The stream to write to
  Throws:
    `java.io.IOException` - throws an I/O exception if one occurred

### writeEnd

    protected void writeEnd(java.io.OutputStream os)
                     throws java.io.IOException

  Helper method to write the end of the Object.

  Overrides:
    `writeEnd` in class `AbstractStructuredObject`
  Parameters:
    `os` - The stream to write to
  Throws:
    `java.io.IOException` - an I/O exception if one occurred

### endControlSequence

    public void endControlSequence()

  A control sequence is a sequence of bytes that specifies a control function. A control sequence consists of a control sequence introducer and zero or more parameters. The control sequence can extend multiple presentation text data objects, but must eventually be terminated. This method terminates the control sequence.

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `AbstractNamedAFPObject`
