Method Detail

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. Unlike text(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 specified Charset. 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.
