Description

A Windows file mapping is the association of a file's contents with a portion of the virtual address space of a process within a Windows operating system. The system creates a file mapping object (also known as a section object) to maintain this association. A file view is the portion of virtual address space that a process uses to access the file's contents. File mapping allows the process to use both random input and output (I/O) and sequential I/O. It also allows the process to work efficiently with a large data file, such as a database, without having to map the whole file into memory. Multiple processes can also use memory-mapped files to share data. Processes read from and write to the file view using pointers, just as they would with dynamically allocated memory. The use of file mapping improves efficiency because the file resides on disk, but the file view resides in memory.[based on https://docs.microsoft.com/en-us/windows/win32/memory/file-mapping]

Shape Properties

Instances of observable:WindowsFilemapping can have the following properties:

PROPERTY	PROPERTY TYPE	DESCRIPTION	MIN COUNT	MAX COUNT	LOCAL TYPE (type defined for property on this class)	GLOBAL RANGE (type range for property globally)

observable:hasChanged	owl:DatatypeProperty		0	1	xsd:boolean	xsd:boolean
observable:state	owl:DatatypeProperty		0	1	xsd:string	xsd:string
core:UcoObject
core:createdBy	owl:ObjectProperty	The identity that created a characterization of a concept.	0	1	core:IdentityAbstraction	core:IdentityAbstraction
core:description	owl:DatatypeProperty	A description of a particular concept characterization.	0	*	xsd:string	xsd:string
core:externalReference	owl:ObjectProperty	Specifies a reference to a resource outside of the UCO.	0	*	core:ExternalReference	core:ExternalReference
core:hasFacet	owl:ObjectProperty	Further sets of properties characterizing a concept based on the particular context of the class and of the particular instance of the concept being characterized.	0	*	core:Facet	core:Facet
core:id	owl:DatatypeProperty	A globally unique identifier for a characterization of a concept.	0	1	types:Identifier	types:Identifier
core:modifiedTime	owl:DatatypeProperty	Specifies the time that this particular version of the object was modified. The object creator can use the time it deems most appropriate as the time this version of the object was modified. The value of the modified property for a given object version MUST be later than or equal to the value of the created property. Object creators MUST update the modified property when creating a new version of an object. The modified timestamp MUST be precise to the nearest millisecond (exactly three digits after the decimal place in seconds).	0	*	xsd:dateTime	xsd:dateTime
core:name	owl:DatatypeProperty	The name of a particular concept characterization.	0	1	xsd:string	xsd:string
core:objectCreatedTime	owl:DatatypeProperty	The time at which a characterization of a concept is created. This time pertains to the time of creating the record object, and is not an intrinsic characteristic of the concept.	0	1	xsd:dateTime	xsd:dateTime
core:objectMarking	owl:ObjectProperty	Marking definitions to be applied to a particular concept characterization in its entirety.	0	*	core:MarkingDefinitionAbstraction	core:MarkingDefinitionAbstraction
core:specVersion	owl:DatatypeProperty	The version of UCO ontology or subontology specification used to characterize a concept.	0	1	xsd:string	xsd:string
core:tag	owl:DatatypeProperty	A generic tag/label.	0	*	xsd:string	xsd:string
core:type	owl:DatatypeProperty	The explicitly-defined type of characterization of a concept.	0	*	xsd:string	xsd:string
