PDF supports eight basic types of objects:
"Boolean value", "Integer and real number", "String", "Name", "Array", "Dictionary", "Stream", "The null
object". For more details about PDF objects, please refer to Section 3.2 "Objects" in <PDF Reference 1.7>.
Class PDFObject is a base class for all kinds of PDF objects. It offers different functions to create different kind of PDF objects. For "Array", "Dictionary" and "Stream" PDF object, please refer to derived classes com.foxit.sdk.pdf.objects.PDFArray , com.foxit.sdk.pdf.objects.PDFDictionary and PDFStream .
If user wants to make a newly created PDF object to be an indirect object, please call function pdf.PDFDoc.addIndirectObject .
PDFObject com.foxit.sdk.pdf.objects.PDFObject.cloneObject | ( | ) |
Clone current PDF object and get the cloned PDF object.

static |
Create a PDF object from a boolean value.
[in] | boolean_value | A boolean value. |
|
static |
Create a PDF object from date time.
PDF defines a standard date format, which closely follows that of the international standard ASN.1 (Abstract Syntax Notation One), defined in ISO/ IEC 8824 (see the Bibliography). A date is defined as an ASCII string of the form (D:YYYYMMDDHHmmSSOHH'mm').
[in] | date_time | A date and time object. |
|
static |
Create a PDF object from a float number.
[in] | float_value | A float value. |
|
static |
Create a PDF object from a integer number.
[in] | integer_value | An integer value. |
|
static |
Create a PDF object from a string which represents a name.
[in] | name | A string. It should not be an empty string. |
|
static |
Create a PDF object from string.
[in] | string_value | A string. It should not be an empty string. |
|
static |
Create a reference for an indirect object.
The indirect object can be retrieved by following methods:
[in] | document | A valid PDF document object. |
[in] | object_number | The indirect object number of the indirect PDF object. This should be above 0. |
PDFObject com.foxit.sdk.pdf.objects.PDFObject.deepCloneObject | ( | ) |
Clone current PDF object and get the cloned PDF object.
This function is a totally direct copy, without any reference object inside, so the copy object can be copied to another document.

Get the PDF array object of current PDF object.
If the type of current PDF object is com.foxit.sdk.pdf.objects.PDFObject.e_Reference , this function will check the direct PDF object of current PDF object.
boolean com.foxit.sdk.pdf.objects.PDFObject.getBoolean | ( | ) | throws com.foxit.sdk.PDFException |
Get the boolean value of current PDF object.
Only useful when the type of current PDF object is com.foxit.sdk.pdf.objects.PDFObject.e_Boolean .
DateTime com.foxit.sdk.pdf.objects.PDFObject.getDateTime | ( | ) | throws com.foxit.sdk.PDFException |
