Method Detail

addResource

@Nullable
public Resource addResource(java.lang.String fileName,
                            byte[] data)

Adds another Resource, so that it can later be found with findResource(String), ResourceFinder.findResourceAsStream(String) and resources().

Returns:

The resource that was previously associated with the fileName, or null

addResource

@Nullable
public Resource addResource(java.lang.String fileName,
                            java.lang.String data)

Parameters:

data - The text to store (in platform default encoding)

Returns:

The resource that was previously associated with the fileName, or null

addResource

public Resource addResource(Resource resource)

Adds another Resource, so that it can later be found with findResource(String), ResourceFinder.findResourceAsStream(String) and resources().

Returns:

The resource that was previously associated with the fileName, or null

resources

public java.util.Collection<Resource> resources()

Returns:

All resources that were previously added with addResource(Resource)

setLastModified

public final void setLastModified(long lastModified)

Parameters:

lastModified - The return value of Resource.lastModified() for the next resources added

findResource

@Nullable
public final Resource findResource(java.lang.String resourceName)

Description copied from class: ResourceFinder

Finds a resource by name and return it as a Resource object.

Specified by:

findResource in class ResourceFinder

Parameters:

resourceName - Designates the resource; typically structured by slashes ("/") like "com/foo/pkg/Bar.class"

Returns:

null if the resource could not be found

list

@Nullable
public java.lang.Iterable<Resource> list(java.lang.String resourceNamePrefix,
                                         boolean recurse)

Description copied from class: ListableResourceFinder

Returns all resources who's names start with a given string. Only resources with a content are included, no "special entries" of any kind, e.g. directories.

If the prefix string ends with "/", you will get a proper directory listing (recurse=false) or directory tree (recurse=true). Example:

   resourceFinder.list("dir/", true) =>
     dir/
     dir/afile
     dir/bfile
     dir/adir/
     dir/adir/file
     dir/bdir/
     dir/bdir/file
 

Otherwise, you will get a strange subset of a directory listing, resp. directory tree, as follows:

   resourceFinder.list("dir/a", true) =>
     dir/afile
     dir/adir/
     dir/adir/file
 

Specified by:

list in class ListableResourceFinder

Parameters:

resourceNamePrefix - E.g. "" or "java/lang/"

Returns:

All resources who's name starts with the given prefix; null iff a location designated by the resourceNamePrefix does not exist
