ThirdPartyPackageVersion

Internal class representing a specific version of a third-party package. Contains the semantic version, .unitypackage file path, description, and upload ID. Created exclusively through static factory methods for two source types: local manifests and Asset Store packages.

Definition

Namespace: Paragon.Editor.ThirdPartyPackageImporter Assembly: Paragon.Editor.dll

internal class ThirdPartyPackageVersion

Remarks

The constructor is private — instances are created via FromLocalManifest() or FromStorePackage(). The AssetPath points to the .unitypackage file on disk; Available checks that this path exists, which determines whether the version can be extracted and imported.

Version String

The VersionString property returns the explicit versionString field if set, otherwise falls back to the SemVersion's implicit string conversion (Major.Minor.Patch).

Properties

Property	Type	Access	Description
Available	bool	public	true if AssetPath is non-empty and the file exists on disk
Version	SemVersion	public	Parsed semantic version (supports comparison operators)
VersionString	string	public	Display string — explicit string if set, otherwise SemVersion.ToString()
AssetPath	string	public	Absolute path to the .unitypackage file
Description	string	public	Version description or package description fallback
UploadID	int	public	Asset Store upload identifier (0 for local manifests)

Operators

Operator	Description
implicit operator string	Converts to string via ToString() (returns SemVersion string)

Static Factory Methods

FromLocalManifest

Creates a version from a local ThirdPartyPackageManifest (a package.json in the Third-Party/ directory).

public static ThirdPartyPackageVersion FromLocalManifest(ThirdPartyPackageManifest packageManifest)

Parameter	Type	Description
packageManifest	ThirdPartyPackageManifest	Local manifest with version string, description, and folder path

Asset path resolution: Searches the manifest folder for a file matching *[{versionString}].unitypackage. If no matching file is found, AssetPath is null and Available returns false.

UploadID: Set to 0 for local manifests.

FromStorePackage

Creates a version from an Asset Store package and version entry.

public static ThirdPartyPackageVersion FromStorePackage(Package package, PackageVersion packageVersion)

Parameter	Type	Description
package	Package	Store package (provides fallback description)
packageVersion	PackageVersion	Specific version entry (provides version string, local path, upload ID)

Description fallback: Uses packageVersion.description if non-empty, otherwise falls back to package.product.description.

Common Pitfalls

Check Available before calling Extract(). A version may exist as metadata (from the store) without the .unitypackage file being downloaded locally. Always check Available before passing a version to ThirdPartyPackage.Extract().

SemVersion supports implicit string conversion. Both ToString() and the implicit string operator return the semantic version string. SemVersion also supports comparison operators, so versions can be compared directly: version1.Version > version2.Version.
