streaming
public static IResourceDescriptor streaming(IResourceDescriptor delegate, ISerializableUnaryOperator<InputStream> transformer)
Creates a resource descriptor that that delegates to another descriptor, but applies a transformer to the input stream of the resource's content. Unliketext(IResourceDescriptor, Charset, ISerializableUnaryOperator)
, this does not read the content into memory and may be more efficient.- Parameters:
delegate
- Delegate from which to obtain the URI and the content.transformer
- Transformer that transforms the input stream of the delegate.- Returns:
- A resource descriptor that transforms the resource content with the given transformer.

text
public static IResourceDescriptor text(IResourceDescriptor delegate, Charset charset, ISerializableUnaryOperator<String> transformer)
Creates a resource descriptor that that delegates to another descriptor, but applies a transformer to the plain text content of the resource, using a specifiedCharset
. The content of the resource is read into memory, but only when the resource content is requested.- Parameters:
delegate
- Delegate from which to obtain the URI and the content.charset
- Charset for reading the content of the delegate as a string and converting the result back to bytes.transformer
- Transformer for the resource content.- Returns:
- A resource descriptor that transforms the resource content with the given transformer.
