Method Detail

service

public void service(ServiceManager manager)
             throws ServiceException

Specified by:

service in interface Serviceable

Throws:

ServiceException

hasVariable

public boolean hasVariable(String path)

Returns true if the path contains variables to be resolved.
If it returns false, then resolvePath(String, List, Extraction, Path) can be called with null parameters for contents and extraction.

Parameters:

path - The relative path to resolve

Returns:

true if the path contains variables to be resolved

isFolder

public boolean isFolder(String path)

Returns true if the unresolved path represents a folder, i.e. its last element does not contain a '.' character.

Parameters:

path - The relative path to resolve

Returns:

true if the unresolved path represents a folder

resolvePath

public Map<Path,List<Content>> resolvePath(String path,
                                                 List<Content> contents,
                                                 Extraction extraction,
                                                 Path basePath)

Resolve the given path, which can contain variables, with the values for the given contents.
Thus, the result is a Map of resolved Paths, each value containg the list of contents for its associated resolved path key.
If a variable is multivalued, a content can be in several paths at the same time in the result.

For instance, foo/a_${meta1/meta2/meta3}_m_${meta4}_z/bar\qux/${meta5} could be resolved to the path foo / a_val1_m_val2_z / bar / qux / val3 for some contents.

Parameters:

path - The relative path to resolve. It must not start, nor end with a '/' or a '\' character

contents - The contents. Can be null if hasVariable(String) was called before and returned false.

extraction - The extraction. Can be null if hasVariable(String) was called before and returned false.

basePath - The base absolute path

Returns:

The absolute resolved paths mapped with their matching contents.
If the returned map contains only one path with a null list, it means that all contents match for that given single path.
