GLXFManager Class

Modifiers: final
GLXFManager is a class that manages the inflation of glXF files into Spatial SDK entities. It manages the full lifecycle of glXFs that are inflated, including deletion.
For more info on how to use glXFs, visit our docs.
Example of inflating a glXF file: 
// ImmersiveActivity.kt(your Spatial SDK activity)
private fun loadGLXF() {
  activityScope.launch {
    glXFManager.inflateGLXF(Uri.parse("apk:///demoproject1.glxf"))
  }
}

Methods

addReloadedGLXFUris ( toReloadUris , basePath )
Adds URIs that should be loaded using the local file system instead of the APK file system. This is used when hot reloading to reload GLXFs so that future GLXFs use the reloaded files. It is recommended not to use this unless you know what you're doing.
Parameters
toReloadUris: Set  The URIs that have been reloaded and use the local file system instead of the APK file system.
basePath: File  The base path of the reloaded files.
deleteGLXF ( glxfInfo )
Deletes root entity and all children. Removes references to the deleted GLXFInfo from the maps.
Example: 
// ImmersiveActivity.kt(your Spatial SDK activity)
glXFManager.deleteGLXF(glXFInfo)
Signature 
fun deleteGLXF(glxfInfo: GLXFInfo)
Parameters
glxfInfo: GLXFInfo  The GLXFInfo to remove.
deleteGLXF ( entity )
Deletes the GLXFInfo the entity belongs to along with all other entities in that GLXFInfo.
Example: 
// ImmersiveActivity.kt(your Spatial SDK activity)
// If you have a reference to the root entity but not the GLXFInfo
glXFManager.deleteGLXF(gltfxEntity)
Signature 
fun deleteGLXF(entity: Entity)
Parameters
entity: Entity  The entity associated with GLXF to remove.
deleteGLXFEntityAndGetDeletedChildren ( entity )
Deletes a GLXF entity and get the deleted children. This is used for handling the deletion of children entities when deleting a GLXF entity. It is recommended not to use this unless you know what you're doing.
Example: 
// ImmersiveActivity.kt(your Spatial SDK activity)
val deletedChildren = glXFManager.deleteGLXFEntityAndGetDeletedChildren(gltfxEntity)
for (childEntity in deletedChildren) {
  // Do something with each deleted child entity
  println("Deleted child entity: $childEntity")
}
Signature 
fun deleteGLXFEntityAndGetDeletedChildren(entity: Entity): Set<Entity>
Parameters
entity: Entity  The entity to delete.
Returns
Set  A set of deleted children entities.

fun getGLXFInfo(keyName: String): GLXFInfo
Parameters
keyName: String  The key name of the GLXFInfo object to retrieve.

hasGLXFInfoForUri ( uri )
Checks if there is a GLXFInfo object for a given URI. This is useful for checking if a glXF file is in use. It is used mostly for hot reloading glXFs. 
// ImmersiveActivity.kt(your Spatial SDK activity)
val uri = Uri.parse("apk:///scenes/Composition.glxf")
if (glXFManager.hasGLXFInfoForUri(uri)) {
  // The GLXF has already been loaded

fun hasGLXFInfoForUri(uri: Uri): Boolean
Parameters
uri: Uri  The URI to check.
Returns
Boolean  True if a GLXFInfo object exists for the URI, false otherwise.
inflateComposition ( compositionName , assetFolderPath , rootEntity , keyName , onLoaded )
Parses the Composition glxf file and calls inflateGLXF, inflates a GLXF file into a GLXFInfo object, adds it to the map of GLXFInfo objects, and sets the GLXF component on the root entity of the GLXF file. 
// ImmersiveActivity.kt(your Spatial SDK activity)
private fun loadGLXF() {
