Field Detail

className

protected java.lang.String className

Name of class that implements module. Must be non-null unless we're currently compiling the module, in which case sourcePath and comp must both be non-null.

sourcePath

public java.lang.String sourcePath

Location of source for module, if known. This can be any of an absolute URI, absolute filename, or filename relative to current working directory. Null if source not known; in that case className must be non-null. Avoid using, since "relative to current working directory" is unreliable if the working directory can change.

lastCheckedTime

public long lastCheckedTime

lastModifiedTime

public long lastModifiedTime

Last time the source file was modified. At least the last time we checked ...

Method Detail

getNamespaceUri

public java.lang.String getNamespaceUri()

The namespace URI associated with this module, or null. This is null for Scheme modules, but non-null for XQuery modules.

setNamespaceUri

public void setNamespaceUri(java.lang.String uri)

getCompilation

public Compilation getCompilation()

setCompilation

setClassName

public void setClassName(java.lang.String name)

getModuleExpRaw

public ModuleExp getModuleExpRaw()

getModuleExp

public ModuleExp getModuleExp()

setupModuleExp

public ModuleExp setupModuleExp()

If module has LAZY_DECLARATIONS, fix that.

getModuleClass

public java.lang.Class getModuleClass()
                               throws java.lang.ClassNotFoundException

Throws:

java.lang.ClassNotFoundException

getModuleClassRaw

public java.lang.Class getModuleClassRaw()

getOldModuleClass

public java.lang.Class getOldModuleClass()

setModuleClass

public void setModuleClass(java.lang.Class clas)

findFromInstance

public static ModuleInfo findFromInstance(java.lang.Object instance)

find

public static ModuleInfo find(ClassType type)

findWithClassName

public static ModuleInfo findWithClassName(java.lang.String className)

register

public static void register(java.lang.Object instance)

getInstance

public java.lang.Object getInstance()

getRunInstance

public java.lang.Object getRunInstance()

getState

public int getState()

loadByStages

public void loadByStages(int wantedState)

loadEager

public boolean loadEager(int wantedState)

Eagerly process the module and dependencies.

Returns:

true on success; false if we were unable to because of an error or a cyclic dependency.

clearClass

public void clearClass()

checkCurrent

public boolean checkCurrent(ModuleManager manager,
                            long now)

Check if this module and its dependencies are up-to-dete. Only checks the sourcePath's modification time if it is at least ModifiedCacheTime since last time we checked. As as side-effects update lastModifiedTime and lastCheckedTime.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
