Method Details
-
getResource
Obtain the object that represents the resource at the given path. Note the resource at that path may not exist.- Parameters:
path
- The path for the resource of interest relative to the root of the web application. It must start with '/'.- Returns:
- The object that represents the resource at the given path
-
list
Obtain the list of the names of all of the files and directories located in the specified directory.- Parameters:
path
- The path for the resource of interest relative to the root of the web application. It must start with '/'.- Returns:
- The list of resources. If path does not refer to a directory then a zero length array will be returned.
-
listWebAppPaths
Obtain the Set of the web applications pathnames of all of the files and directories located in the specified directory. Paths representing directories will end with a "/" character.- Parameters:
path
- The path for the resource of interest relative to the root of the web application. It must start with '/'.- Returns:
- The Set of resources. If path does not refer to a directory then an empty set will be returned.
-
mkdir
Create a new directory at the given path.- Parameters:
path
- The path for the new resource to create relative to the root of the web application. It must start with '/'.- Returns:
true
if the directory was created, otherwisefalse
-
write
Create a new resource at the requested path using the provided InputStream.- Parameters:
path
- The path to be used for the new Resource. It is relative to the root of the web application and must start with '/'.is
- The InputStream that will provide the content for the new Resource.overwrite
- Iftrue
and the resource already exists it will be overwritten. Iffalse
and the resource already exists the write will fail.- Returns:
true
if and only if the new Resource is written
-
setRoot
-
getClassLoaderOnly
boolean getClassLoaderOnly()Should resources returned by this resource set only be included in any results when the lookup is explicitly looking for class loader resources. i.e. should these resources be excluded from look ups that are explicitly looking for static (non-class loader) resources.- Returns:
true
if these resources should only be used for class loader resource lookups, otherwisefalse
-
setClassLoaderOnly
void setClassLoaderOnly(boolean classLoaderOnly) -
getStaticOnly
boolean getStaticOnly()Should resources returned by this resource set only be included in any results when the lookup is explicitly looking for static (non-class loader) resources. i.e. should these resources be excluded from look ups that are explicitly looking for class loader resources.- Returns:
true
if these resources should only be used for static (non-class loader) resource lookups, otherwisefalse
-
setStaticOnly
void setStaticOnly(boolean staticOnly) -
getBaseUrl
URL getBaseUrl()Obtain the base URL for this set of resources. One of the uses of this is to grant read permissions to the resources when running under a security manager.- Returns:
- The base URL for this set of resources
-
setReadOnly
void setReadOnly(boolean readOnly) Configures whether or not this set of resources is read-only.- Parameters:
readOnly
-true
if this set of resources should be configured to be read-only- Throws:
IllegalArgumentException
- if an attempt is made to configure aWebResourceSet
that is hard-coded to be read-only as writable
-
isReadOnly
boolean isReadOnly()Obtains the current value of the read-only setting for this set of resources.- Returns:
true
if this set of resources is configured to be read-only, otherwisefalse
-
gc
void gc()Implementations may cache some information to improve performance. This method triggers the clean-up of those resources.
