Class GltfAssetReader

java.lang.Object

de.javagl.jgltf.model.io.GltfAssetReader

public final class GltfAssetReader
extends java.lang.Object

A class for reading a glTF asset in a version-agnostic form.

The read(URI) method allows reading the asset from a URI. The external references of the asset will be resolved against the parent of the given URI, and loaded automatically. The respective data may then be obtained with GltfAsset.getReferenceData(String).

The readWithoutReferences(URI) and readWithoutReferences(InputStream) methods allow reading an asset from a URI or an input stream, without resolving external references. This is mainly intended for binary- or embedded glTF assets that do not have external references, or for cases where the external references should be resolved manually.

Such a GltfAsset may then be processed further, for example, by creating a GltfModel using GltfModels.create(GltfAsset).

Method Detail

setJsonErrorConsumer

public void setJsonErrorConsumer(java.util.function.Consumer<? super JsonError> jsonErrorConsumer)

Set the given consumer to receive JsonErrors that may occur when a glTF is read

Parameters:

jsonErrorConsumer - The JsonError consumer

read

public GltfAsset read(java.net.URI uri)
               throws java.io.IOException

Read the GltfAsset from the given URI

Parameters:

uri - The URI

Returns:

The GltfAsset

Throws:

java.io.IOException - If an IO error occurs

read

public GltfAsset read(java.nio.file.Path path)
               throws java.io.IOException

Read the GltfAsset from the given path

Parameters:

path - The path

Returns:

The GltfAsset

Throws:

java.io.IOException - If an IO error occurs

readWithoutReferences

public GltfAsset readWithoutReferences(java.net.URI uri)
                                throws java.io.IOException

Read the GltfAsset from the given URI.

In contrast to the read(URI) method, this method will not resolve any external references.

This is mainly intended for binary- or embedded glTF assets that do not have external references.

Parameters:

uri - The URI

Returns:

The GltfAsset

Throws:

java.io.IOException - If an IO error occurs

readWithoutReferences

public GltfAsset readWithoutReferences(java.io.InputStream inputStream)
                                throws java.io.IOException

Read the glTF asset from the given input stream. The caller is responsible for closing the given stream.

In contrast to the read(URI) method, this method will not resolve any external references.

This is mainly intended for binary- or embedded glTF assets that do not have external references, or for cases where the external references should be resolved manually.

Parameters:

inputStream - The input stream

Returns:

The GltfAsset

Throws:

java.io.IOException - If an IO error occurred
