Properties

IsInteger

Gets true because this PDF numeric object is integer value.

public sealed override bool IsInteger { get; }
Public NotOverridable Overrides ReadOnly Property IsInteger As Boolean
Property Value
System.Boolean

true because this PDF numeric object is integer value.

Overrides

Value

Gets a System.Int32 value of this PdfInteger instance.

public int Value { get; }
Public ReadOnly Property Value As Integer
Property Value
System.Int32

A System.Int32 value of this PdfInteger instance.

Methods

Create(Int32)

Creates the PdfInteger instance from the specified System.Int32 value.

public static PdfInteger Create(int value)
Public Shared Function Create(value As Integer) As PdfInteger
Parameters
value
System.Int32

The integer value.

Returns
PdfInteger

A PdfInteger instance created from the specified System.Int32 value.

Remarks

GemBox.Pdf assembly doesn't publicly expose constructors for types assignable from PdfObject (except PdfDocument), PdfContentElement, and PdfBasicObject types. These types are instead instantiated either through static Create or other factory methods.

Reasons for this is to support either the current or future extensibility of the type without affecting backward compatibility and without using composition to reduce the number of object allocations.

For example, PdfNumber type is implemented as PdfInteger and internal PdfReal type. When using Create(Double) method, GemBox.Pdf assembly is able to create either PdfReal or PdfInteger, or return a cached instance of PdfInteger available for an implementation-defined interval of integers, thus reducing memory overhead.

PdfString and PdfName types have several internal implementations that reduce the number of System.Array allocations.

PdfArray type is currently implemented as a dynamic array. In the future, GemBox.Pdf assembly might provide an internal implementation that is immutable (without a need to use composition) to reduce memory overhead and optimize cloning operation.

PdfDictionary type is currently implemented as a hash table with a separate chaining collision resolution. In the future, GemBox.Pdf assembly might provide an internal implementation that uses dynamic array (without a need to use composition) if number of entries is small, to reduce memory overhead and, potentially, improve performance.

All these current and future implementations would not be possible in a backward compatible way (without unnecessary usage of composition) if constructors were publicly exposed.
