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, PDFReal represents a single floating point value. Others represent a collection of PDFObjects, such as PDFArray, an indexed array of data elements. A PDFReal represents a single floating point value, and may be inserted into any collection object. **Uses types:** [`Document`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/Document.md), [`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md), [`PDFObjectComparison`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/enum/PDFObjectComparison.md), [`PDFObjectEnumProc`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObjectEnumProc.md) ## Constructors ### PDFReal ```csharp Datalogics.PDFL.PDFReal.PDFReal(double value, Document doc, bool indirect) ``` *constructor* **Parameters** - `value` (`double`): Double value of this PDFReal - `doc` ([`Document`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/Document.md)): Document object containing this PDFReal - `indirect` (`bool`): flag marking this as an indirect PDFObject General constructor ### PDFReal ```csharp Datalogics.PDFL.PDFReal.PDFReal(double value, PDFObject docFromObj, bool indirect) ``` *constructor* **Parameters** - `value` (`double`): Double value of this PDFReal - `docFromObj` ([`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md)): The new PDFArray will be created in the same document as this object. - `indirect` (`bool`): flag marking this as an indirect PDFObject General constructor ## Properties ### Document ```csharp Document Datalogics.PDFL.PDFObject.Document { get; } ``` The Document of which this object is a member. Returns null if the Document is not known by PDFL, or if it is a temporary document. If the Document is not null, then it shares the same internal data with other Document objects that refer to the same file. Document objects returned this way do not contribute to the internal count that keeps the Document open, and will become invalid if the main reference to the document is disposed. ### Generation ```csharp int Datalogics.PDFL.PDFObject.Generation { get; } ``` The generation number for this object. Only indirect objects have a generation number. **Exceptions** - `ApplicationException`: direct objects do not have a generation number. ### ID ```csharp int Datalogics.PDFL.PDFObject.ID { get; } ``` The ID number for this object. Only indirect objects have an ID number. **Exceptions** - `ApplicationException`: direct objects do not have an ID number. ### Indirect ```csharp bool Datalogics.PDFL.PDFObject.Indirect { get; } ``` Indicates if this object is indirect or direct. ### PDFHashValue ```csharp int Datalogics.PDFL.PDFObject.PDFHashValue { get; } ``` The 32-bit hash value for this object. The hash value is used internally to quickly access the object, and is not generally useful for PDFObject users. Note that two PDFObjects with equal hash values are not necessarily equal; use Equals() to check for equality. ### Value ```csharp double Datalogics.PDFL.PDFReal.Value { get; } ``` Floating-point value of this object. ## Methods ### Clone ```csharp PDFObject Datalogics.PDFL.PDFObject.Clone() ``` **Returns:** [`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md) A new PDFObject that is a copy of this object. Makes a new copy of this PDFObject in memory, in the same document and using same direct/indirect setting as this PDFObject. ### Clone ```csharp PDFObject Datalogics.PDFL.PDFObject.Clone(Document doc) ``` **Parameters** - `doc` ([`Document`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/Document.md)): The target document in which to create the copy. **Returns:** [`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md) A new PDFObject that is a copy of this object in the specified document. Makes a new copy of this PDFObject in memory, in the supplied document, using the same direct/indirect setting as this PDFObject. ### Clone ```csharp PDFObject Datalogics.PDFL.PDFObject.Clone(Document doc, bool indirect) ``` **Parameters** - `doc` ([`Document`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/Document.md)): The target document in which to create the copy. - `indirect` (`bool`): If true, the copy will be an indirect object; if false, it will be direct. **Returns:** [`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md) A new PDFObject that is a copy of this object in the specified document. Makes a new copy of this PDFObject in memory, in the supplied document, using supplied direct/indirect setting. ### Clone ```csharp PDFObject Datalogics.PDFL.PDFObject.Clone(PDFObject obj) ``` **Parameters** - `obj` ([`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md)): The reference object whose document will be used for the copy. **Returns:** [`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md) A new PDFObject that is a copy of this object in the same document as obj. Makes a new copy of this PDFObject in memory, in the same document as another object, using the same direct/indirect setting as this PDFObject. ### Clone ```csharp PDFObject Datalogics.PDFL.PDFObject.Clone(PDFObject obj, bool indirect) ``` **Parameters** - `obj` ([`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md)): The reference object whose document will be used for the copy. - `indirect` (`bool`): If true, the copy will be an indirect object; if false, it will be direct. **Returns:** [`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md) A new PDFObject that is a copy of this object in the same document as obj. Makes a new copy of this PDFObject in memory, in the same document as another object, using supplied direct/indirect setting. ### CompareTo ```csharp PDFObjectComparison Datalogics.PDFL.PDFObject.CompareTo(PDFObject rhs) ``` **Parameters** - `rhs` ([`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md)): the other PDFObject to compare. **Returns:** [`PDFObjectComparison`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/enum/PDFObjectComparison.md) A PDFObjectComparison value that relates this object to the rhs object Compares this object to another object. The result is useful for ordering or sorting PDFObjects. No other significance should be attached to the result. In particular, an unequal result indicates nothing about the type of either object. The result is valid only within a single instance of the document. ### Destroy ```csharp void Datalogics.PDFL.PDFObject.Destroy() ``` **Returns:** `void` Destroys this object. This method does nothing if this object is a direct scalar object. If a composite object (an array, dictionary or stream) is destroyed: • All the direct objects in it are automatically destroyed. • The indirect objects in it are not destroyed. ### Dispose ```csharp void Datalogics.PDFL.PDFObject.Dispose() ``` **Returns:** `void` ### EnumPDFObjects ```csharp bool Datalogics.PDFL.PDFObject.EnumPDFObjects(PDFObjectEnumProc enumProc) ``` **Parameters** - `enumProc` ([`PDFObjectEnumProc`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObjectEnumProc.md)): A user-supplied callback to call for each element of the object. of obj. Neither proc nor any routine called by proc may modify the object. Doing so can produce undefined results or errors. For example, if the object is an array, enumProc must not call Remove(); if the object is a dictionary, enumProc must not call Put(). **Returns:** `bool` Returns true if every call to enumProc returned true. As soon as any call to enumProc returns false, the enumeration stops and EnumPDFObject() returns false. Enumerates the elements of a PDFObject by calling a user-supplied procedure for each component of the object. • For scalars or strings, the proc is not called, and CosObjEnum() returns true. • For dictionaries, proc is called for each key-value pair. The order in which the key-value pairs are enumerated is undefined. • For arrays, proc is called with each element as the first paramater to proc, and the NULL object as the second parameter. Array elements are enumerated in ascending order of index. • For streams, proc is called once, with the stream's dictionary as the first parameter to the proc and the NULL object as the second parameter. ### Equals ```csharp override bool Datalogics.PDFL.PDFObject.Equals(object obj) ``` **Parameters** - `obj` (`object`) **Returns:** `override bool` ### ToString ```csharp override string Datalogics.PDFL.PDFReal.ToString() ``` **Returns:** `override string` A string describing this PDFReal, including its value and properties. Returns a string representation of this PDFReal object. The returned string includes property information and the floating-point value in a human-readable format.
