ThirdPartyPackage

Internal class representing an extracted Unity Asset Store package ready for processing and import. Wraps the package metadata (ThirdPartyPackageInfo), version (ThirdPartyPackageVersion), extracted import items, icon path, and ProcessorTable. Implements IEnumerable<ImportPackageItem> for iterating over all items.

Definition

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

internal class ThirdPartyPackage : IEnumerable<ImportPackageItem>

Implements: IEnumerable<ImportPackageItem>

Remarks

ThirdPartyPackage is created exclusively through the static Extract() factory method, which:

1. Retrieves the ProcessorTable for the package's product ID from ThirdPartyPackageProcessor

2. Extracts all assets from the .unitypackage file via Unity's internal PackageUtility.ExtractAndPrepareAssetList()

3. Wraps each extracted asset as a proxy ImportPackageItem

The constructor is private — direct instantiation is not allowed.

Properties

Property	Type	Access	Description
IconPath	string	public	File path to the package's icon texture
Info	ThirdPartyPackageInfo	public	Package identity and metadata
Version	ThirdPartyPackageVersion	public	The specific version being imported

Methods

GetProcessedValue

Looks up a key in the processor table within the specified context(s).

public string GetProcessedValue(string key, ProcessorTable.Context context = ProcessorTable.Context.ALL)

Returns: The mapped value, or null if not found.

TryGetProcessedValue

Attempts to look up a key in the processor table within the specified context(s).

public bool TryGetProcessedValue(string key, out string value, ProcessorTable.Context context = ProcessorTable.Context.ALL)

Returns: true if the key was found and has a non-empty value.

GetImportItems

Returns only the items marked as visible (filtered by PrepareProcessor during pre-processing).

public IEnumerable<ImportPackageItem> GetImportItems()

GetEnumerator

Iterates over all import items (including non-visible ones).

public IEnumerator<ImportPackageItem> GetEnumerator()

GetImportItems() vs enumerating directly. Iterating the package directly (foreach item in package) returns all items. GetImportItems() filters to only items where Visible == true. Pre-processors like PathProcessor iterate all items; post-processors typically use GetImportItems().

Static Methods

Extract

Factory method that creates a ThirdPartyPackage by extracting assets from the .unitypackage file.

public static ThirdPartyPackage Extract(ThirdPartyPackageInfo packageInfo, ThirdPartyPackageVersion version)

Parameter	Type	Description
packageInfo	ThirdPartyPackageInfo	Package metadata (product ID, names, etc.)
version	ThirdPartyPackageVersion	The version to extract (provides the .unitypackage asset path)

Returns: A fully extracted ThirdPartyPackage with all import items and processor table.
