PDFInteger Class

classPDFInteger : PDFObject

Namespace:datalogics_interface

Inherits from:: PDFObject

Detailed Description

All objects in a PDF document are built from a collection of simpler objects that represent fundamental datatypes like numbers, strings and arrays. PDFObject and its subclasses allow direct access and manipulation of these simple objects. Some subclasses represent single data elements. For example, PDFInteger represents a single integer value. Others represent a collection of PDFObjects, such as PDFArray, an indexed array of data elements.

A PDFInteger represents a single integer value, and may be inserted into any collection object.

Constructor & Destructor Documentation

PDFInteger(intvalue, Document &doc, boolindirect)

Parameters

value: int: Integer value of this PDFInteger
doc: Document &: Document object containing this PDFInteger
indirect: bool: flag marking this as an indirect PDFObject

General constructor

Member Function Documentation

intget_generation()

Returns:

The generation number of this indirect object.

Only indirect objects have a generation number.

intget_id()

Returns:

The ID number of this indirect object.

Only indirect objects have an ID number.

boolget_indirect()

Returns:

true if this object is indirect, false if it is direct.

Indicates if this object is indirect or direct.

PDFObjectTypeget_type()

Returns:

PDFObjectType

The underlying Cos type of this object. Prefer this over dynamic_cast/try_as chains in hot paths.

intget_value()

Returns:

int

Integer value of this object.

booloperator!=(const PDFObject &other)

Parameters

other: const PDFObject &

Returns:

true if <code>other</code> is not equal to this.

Inequality.

booloperator==(const PDFObject &other)

Parameters

other: const PDFObject &: The other PDFObject to compare against.

Returns:

true if the two objects are equal, false otherwise.

Compare if two objects are equal.

std::stringto_string()

Returns:

A string describing this PDFObject.

The string includes the object's indirect status, and if indirect, its ID and generation number.

T *try_as(typename T)

Parameters

: typename T

Returns:

T *

Attempt to downcast this object to a derived Cos type such as PDFString, PDFDict, PDFArray, PDFStream, PDFName, PDFInteger, PDFReal, or PDFBoolean. Returns nullptr if the object's actual type doesn't match T.

const T *try_as(typename T)

Parameters

: typename T

Returns:

const T *

Const overload of try_as(). Returns a const pointer, or nullptr.
