Method Detail

getText

public java.lang.String getText()

Returns the text.

Returns:

the text

setText

public void setText(java.lang.String text)

Sets the text.

Parameters:

text - the text

toPDFString

protected java.lang.String toPDFString()

Description copied from class: PDFObject

This method returns a String representation of the PDF object. The result is normally converted/encoded to a byte array by toPDF(). Only use this method to implement the serialization if the object can be fully represented as text. If the PDF representation of the object contains binary content use toPDF() or output(OutputStream) instead.

Overrides:

toPDFString in class PDFObject

Returns:

String the String representation
