Constructor Detail

WebappStructure

public WebappStructure(List<org.apache.maven.model.Dependency> dependencies)

Creates a new empty instance.

Parameters:

dependencies - the dependencies of the project

Method Detail

getDependenciesInfo

public List<DependencyInfo> getDependenciesInfo()

Returns the list of DependencyInfo for the project.

Returns:

the dependencies information of the project

getDependencies

public List<org.apache.maven.model.Dependency> getDependencies()

Returns the dependencies of the project.

Returns:

the dependencies of the project

isRegistered

public boolean isRegistered(String path)

Specify if the specified path is registered or not.

Parameters:

path - the relative path from the webapp root directory

Returns:

true if the path is registered, false otherwise

registerFile

public boolean registerFile(String id,
                            String path)

Registers the specified path for the specified owner. Returns true if the path is not already registered, false otherwise.

Parameters:

id - the owner of the path

path - the relative path from the webapp root directory

Returns:

true if the file was registered successfully

registerFileForced

public boolean registerFileForced(String id,
                                  String path)

Forces the registration of the specified path for the specified owner. If the file is not registered yet, a simple registration is performed. If the file already exists, the owner changes to the specified one.

Beware that the semantic of the return boolean is different than the one from registerFile(String, String); returns true if an owner replacement was made and false if the file was simply registered for the first time.

Parameters:

id - the owner of the path

path - the relative path from the webapp root directory

Returns:

false if the file did not exist, true if the owner was replaced

registerFile

public void registerFile(String id,
                         String path,

                  throws IOException

Registers the specified path for the specified owner. Invokes the callback with the result of the registration.

Parameters:

id - the owner of the path

path - the relative path from the webapp root directory

callback - the callback to invoke with the result of the registration
