ScriptProcessorRegistry

public ScriptProcessorRegistry()

Method Detail

setDefaultScriptProcessor

public void setDefaultScriptProcessor(String defaultScriptProcessorName)

Sets the name of the default script processor

Parameters:

defaultScriptProcessor - the name of the default script processor

registerScriptProcessor

public void registerScriptProcessor(ScriptProcessor scriptProcessor)

Registers a script processor

Parameters:

scriptProcessor - the script processor to register

registerScriptProcessor

public void registerScriptProcessor(ScriptProcessor scriptProcessor,
                                    String extension,
                                    String name)

Registers a script processor

Parameters:

scriptProcessor - the script processor to register

extension -

name -

getDefaultScriptProcessor

protected ScriptProcessor getDefaultScriptProcessor()

Gets the default script processor.

Returns:

the default script processor

getScriptProcessor

public ScriptProcessor getScriptProcessor(String path)

Returns the script processor that matches the file extension for the given path. If a script processor cannot be matched to the path, the default script processor will be returned.

Parameters:

path - the path

Returns:

the script processor

getScriptProcessor

public ScriptProcessor getScriptProcessor(ScriptContent scriptContent)

Returns the best fit script processor for the given script content object. If a script processor cannot be matched, the default script processor will be returned.

Parameters:

path - the path

Returns:

the script processor

getScriptProcessorByExtension

public ScriptProcessor getScriptProcessorByExtension(String extension)

Gets the script processor registered for the given extension

Parameters:

extension - the extension

Returns:

the script processor by extension or null if no match

findValidScriptPath

public String findValidScriptPath(String path)

Returns a variation on the provided path that exists and is processable by one of the processors in this registry. First attempts to find a script processor that contains the content located at the given path (using extension information, if available). If no match is found, iterates over the file extensions and attempts to find a match. Path can therefore be values like: testfile.js - matches to file testfile.js using javascript procesor testfile - matches for all extensions, potentially looking at testfile.js, testfile.groovy, etc. The extension annotated path is returned which will correctly dispatch to the discovered processor.

Parameters:

path - the path

Returns:

a valid processor file path or null if no match

getRegisteredExtensions

public String[] getRegisteredExtensions()

Returns the extensions with registered processors

Returns:

the registered extensions

getExtensionForProcessor

public String getExtensionForProcessor(ScriptProcessor scriptProcessor)

Gets the extension for given processor.

Parameters:

scriptProcessor - the script processor

Returns:

the extension for processor

reset

public void reset()

Resets all of the registered script processors
