Description copied from class: ResourceHelper

If a ResourceInfo is not compressable, ResourceHelper.getInputStream(ResourceInfo, javax.faces.context.FacesContext) will call this method to return a stream to the actual resource.

Specified by:

getNonCompressedInputStream in class ResourceHelper

Parameters:

resource - the resource to obtain an InputStream to

ctx - the FacesContext for the current request

Returns:

an InputStream to the resource

Throws:

IOException - if an error occurs obtaining the stream

Specified by:

getURL in class ResourceHelper

Parameters:

resource - the resource to obtain a URL reference to

ctx - the FacesContext for the current request

Returns:

a URL to the specified resource, otherwise null if no resource is found

                               FacesContext ctx)

Description copied from class: ResourceHelper

Search for the specified library/localPrefix combination in an implementation dependent manner.

Specified by:

findLibrary in class ResourceHelper

Parameters:

libraryName - the name of the library

localePrefix - the logicial identifier for a locale specific library. if no localePrefix is configured, pass null

contract - the name of the contract

ctx - the FacesContext for the current request @return a LibraryInfo if a matching library based off the inputs can be found, otherwise returns null

findResource

public ResourceInfo findResource(LibraryInfo library,
                                 String resourceName,
                                 String localePrefix,
                                 boolean compressable,
                                 FacesContext ctx)

Description copied from class: ResourceHelper

Search for the specified resource based in the library/localePrefix/resourceName combination in an implementation dependent manner.

If the resource is found, and is compressable, call ResourceHelper.handleCompression(com.sun.faces.application.resource.ClientResourceInfo) to compress the content.

Specified by:

findResource in class ResourceHelper

Parameters:

library - the library this resource should be a part of. If the the resource that is being searched for isn't part of a library, then pass null

resourceName - the name of the resource that is being searched for

localePrefix - the logicial identifier for a locale specific library. if no localePrefix is configured, pass null

compressable - true if the resource can be compressed

ctx - the FacesContext for the current request

Returns:

a ResourceInfo if a matching resource based off the inputs can be found, otherwise returns null
