Properties

	Name	Description
	Count	Returns the number of metadata tags this instance represents.
	Exists	Returns whether this model exists in the bitmaps metadata structure.
	Item	Returns the metadata tag at the given index. This operation is slow when accessing all tags.
	List	Returns a list of all metadata tags this instance represents.
	Model	Retrieves the datamodel that this instance represents.

Methods

	Name	Description
	AddTag(MetadataTag)	Adds new tag to the bitmap or updates its value in case it already exists. Key will be used as key.
	AddTag(IEnumerableMetadataTag)	Adds a list of tags to the bitmap or updates their values in case they already exist. Key will be used as key.
	DestoryModel	Destroys the metadata model which will remove all tags of this model from the bitmap.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetEnumerator	Retrieves an object that can iterate through the individual MetadataTags in this MetadataModel.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetTag	Returns the specified metadata tag.
	GetTagArrayT	Returns an array containing the data of the specified tag.
	GetTagFromIndex	Returns the tag at the given index.
	GetTagText	Returns the string contained by the specified tag.
	GetTagValueT	Returns the value of the specified tag.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetUInt32Array	Returns an array containg the data of the specified tag as unsigned 32bit integer.
	GetUInt32Value	Returns the value of the tag as unsigned 32bit integer.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RegexSearch	Searches for a pattern in each metadata tag and returns the result as a list.
	RemoveTag	Removes the specified tag from the bitmap.
	SetTagValue(String, Object)	Sets the value of the specified tag.
	SetTagValueT(String, NullableT)	Sets the value of the specified tag.
	SetTagValueUndefined	Sets the value of the specified tag as undefined.
	TagExists	Returns whether the specified tag exists.
	ToDirectionType	Returns the equivalent MetadataModelDirectionReference for the specified String.
	ToInteroperabilityType	Returns the equivalent MetadataModelInteroperabilityMode for the specified String.
	ToLatitudeType	Returns the equivalent MetadataModelLatitudeType for the specified String.
	ToLongitudeType	Returns the equivalent MetadataModelLongitudeType for the specified String.
	ToString	Converts the model of the MetadataModel object to its equivalent string representation. (Overrides ObjectToString.)
	ToString(NullableMetadataModelDirectionReference)	Returns the equivalent String for the specified MetadataModelDirectionReference.
	ToString(NullableMetadataModelInteroperabilityMode)	Returns the equivalent String for the specified MetadataModelInteroperabilityMode.
	ToString(NullableMetadataModelLatitudeType)	Returns the equivalent String for the specified MetadataModelLatitudeType.
	ToString(NullableMetadataModelLongitudeType)	Returns the equivalent String for the specified MetadataModelLongitudeType.
	ToString(NullableMetadataModelVelocityUnit)	Returns the equivalent String for the specified MetadataModelVelocityUnit.
	ToUnitType	Returns the equivalent MetadataModelVelocityUnit for the specified String.
