public class ResourceDirectoryParser
extends java.lang.Object
SymbolTable. The
parser expects a resource directory that contains sub-directories with a name in the format
X(-Y)* where X is a pseudo resource type (see below) and Y are
optional qualifiers. Inside each directory, only resource files should exist.
The pseudo resource type is either the resource type or the value values. If
the first segment of the directory name is values, files in the directory are treated as
resource XML values, parsed using ResourceValuesXmlParser and the generated symbol tables
are merged to form the resulting one.
The qualifiers are irrelevant as far as the directory parser is concerned and are ignored.
One symbol will be generated per resource file, with the exception of resource files in the
values directory and resources declared inside other XML files (e.g. "@+string/my_string"
declared inside layout/activity_name.xml would generate a new Symbol of type String and name my_string).
For files the symbol's name is the resource file name with optional extension removed. The only characters allowed in the symbol's name are lowercase letters, digits and the underscore character.
For values declared inside XML files the symbol's name is the element's name XML tag
value. Dots and colons are allowed, but deprecated and therefore support for them will end soon.
Subdirectories in the resource directories are ignored.
For testing purposes, it is guaranteed that the resource directories are processed by name
with all the values directories being processed last. Inside each directory, files are
processed in alphabetical order. All symbols are assigned an ID, even if they are duplicated.
Duplicated symbols are not present in the final symbol table. So, if for example, the following
resources are defined drawable/a.png, drawable-hdpi/a.png and layout/b.xml, two symbols will exist, drawable/a and layout/b with IDs 1
and 3, respectively. This behavior, that ensures ID assignment is deterministic, should
not be relied upon except for testing.
