TResources.FindReader function

Member of TResourcespublicIn unit resource

Searches for a suitable resource reader

Declaration

pascal

class function FindReader(aStream: TStream; aExtension: string)
: TAbstractResourceReader
class function FindReader(aStream: TStream): TAbstractResourceReader

Arguments

`aStream`	The stream to be probed
`aExtension`	The extension the reader is registered for

Function result

An instance of a TAbstractResourceReader descendant.

Description

This method tries to find a resource reader able to read the stream passed as parameter.

If an extension is specified, only readers matching that extension are tried. The extension is case-insensitive and includes the leading dot, unless the empty string is passed (which means "no extension", e.g. a unix executable, which doesn't have an extension).

If a suitable reader is found, an instance of that reader is returned.

To make a resource reader class known, add that resource reader unit to the uses clause of your program.

Errors

If no suitable reader is found, an EResourceReaderNotFoundException exception is raised.
