Field Detail

lastModifiedCacheTime

public long lastModifiedCacheTime

Number millseconds before we re-check file's modified time.

LAST_MODIFIED_CACHE_TIME

public static final long LAST_MODIFIED_CACHE_TIME

Method Detail

clear

public void clear()

Reset the set of known modules.

find

public ModuleInfo find(Compilation comp)

findWithClassName

public ModuleInfo findWithClassName(String className)

findWithSourcePath

public ModuleInfo findWithSourcePath(Path sourceAbsPath, String sourcePath)

findWithSourcePath

public ModuleInfo findWithSourcePath(String sourcePath)

getInstance

public static ModuleManager getInstance()

For now assumes a single global ModuleManager. Later, might have multiple managers.

loadPackageInfo

public void loadPackageInfo(String packageName)

Search for and if needed load the ModuleSet for a package.

register

public void register(String moduleClass, String moduleSource, String moduleUri)

Called by compiler-generated code. The compiler generates in each package a class that extends ModuleSet, and that contains a register method that calls back to this method. This method then registers the specified module.

searchWithClassName

public ModuleInfo searchWithClassName(String className)

setCompilationDirectory

public void setCompilationDirectory(String path)
