Method Detail

getInputStreamForResource

public InputStream getInputStreamForResource(String resourceLocation)
Description copied from interface: IOTools.ResourceLocator
Returns an InputStream that gets its bytes from the specified resource. A return value of null indicates that the resource could not be found (do not throw an exception as the search may continue on to other locators). A return value of null can also be used to indicate that this particular locator can not supply the resource in the desired format (for example, it can not be returned as a URL, but it might be able to be returned as an InputStream).

Specified by:
getInputStreamForResource in interface IOTools.ResourceLocator
Parameters:
resourceLocation - the name of the resource to find.
Returns:
the InputStream or null if the specified resource could not be found by this locator.

Returns a URL that gets its bytes from the specified resource. A return value of null indicates that the resource could not be found (do not throw an exception as the search may continue on to other locators). A return value of null can also be used to indicate that this particular locator can not supply the resource in the desired format (for example, it can not be returned as an URL, but it might be able to be returned as an InputStream).

Specified by:
