Method Detail

getStatus

int getStatus()

Get the parsing status of the element. This is a non-blocking operation.

Returns:

one of SourceElement.STATUS_NOT, SourceElement.STATUS_ERROR, SourceElement.STATUS_PARTIAL, or SourceElement.STATUS_OK

---

prepare

Task prepare()

Begin parsing this source element. This method is non-blocking; it only returns a task that can be used to control the ongoing parse. Initially the getStatus() should be SourceElement.STATUS_NOT, and change to one of the other three when parsing is complete, according to whether or not errors were encountered, and their severity.

Returns:

a task to control the preparation of the element

---

setPackage

void setPackage(Identifier id)
                throws SourceException

Set the package of this source file.

Parameters:

id - the package name, or null to use the default package

Throws:

SourceException - if the operation cannot proceed

---

getPackage

Identifier getPackage()

Get the package of this source file.

Returns:

the package name, or null if this source file is in the default package

---

getImports

Import[] getImports()

Get all imports.

Returns:

the imports

---

changeImports

void changeImports(Import[] elems,
                   int action)
                   throws SourceException

Change the set of imports.

Parameters:

elems - the imports to change

action - one of ADD, REMOVE, or SET

Throws:

SourceException - if the action cannot be handled

---

changeClasses

void changeClasses(ClassElement[] elems,
                   int action)
                   throws SourceException

Change the set of top-level classes.

Parameters:

elems - the classes to change

action - one of ADD, REMOVE, or SET

Throws:

SourceException - if the action cannot be handled

---

getClasses

ClassElement[] getClasses()

Get all top-level classes.

Returns:

the classes

---

getClass

ClassElement getClass(Identifier name)

Find a top-level class by name.

Parameters:

name - the name to look for

Returns:

the class, or null if it does not exist

---

getAllClasses

ClassElement[] getAllClasses()

Get all classes recursively, both top-level and inner.

Returns:

all classes

---

runAtomic

void runAtomic(Runnable run)

Lock the underlaing document to have exclusive access to it and could make changes on this SourceElement.

Parameters:

run - the action to run

---

runAtomicAsUser

void runAtomicAsUser(Runnable run)
                     throws SourceException

Executes given runnable in "user mode" does not allowing any modifications to parts of text marked as guarded. The actions should be run as "atomic" so either happen all at once or none at all (if a guarded block should be modified).

Parameters:

run - the action to run
