Interface IInvocationContext


public interface IInvocationContext

Context information for quick fix and quick assist processors.

Note: this interface is not intended to be implemented.

Provisional API: This class/interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.


Method Summary
 JavaScriptUnit getASTRoot()
          Returns an AST of the compilation unit, possibly only a partial AST focused on the selection offset (see ASTParser.setFocalPosition(int)).
 IJavaScriptUnit getCompilationUnit()
           
 ASTNode getCoveredNode()
          Convenience method to evaluate the AST node that is covered by the current selection.
 ASTNode getCoveringNode()
          Convenience method to evaluate the AST node covering the current selection.
 int getSelectionLength()
           
 int getSelectionOffset()
           
 

Method Detail

getCompilationUnit

IJavaScriptUnit getCompilationUnit()
Returns:
Returns the current compilation unit.

getSelectionOffset

int getSelectionOffset()
Returns:
Returns the offset of the current selection

getSelectionLength

int getSelectionLength()
Returns:
Returns the length of the current selection

getASTRoot

JavaScriptUnit getASTRoot()
Returns an AST of the compilation unit, possibly only a partial AST focused on the selection offset (see ASTParser.setFocalPosition(int)). The returned AST is shared and therefore protected and cannot be modified. The client must check the AST API level and do nothing if they are given an AST they can't handle. (see AST.apiLevel()).

Returns:
Returns the root of the AST corresponding to the current compilation unit.

getCoveringNode

ASTNode getCoveringNode()
Convenience method to evaluate the AST node covering the current selection.

Returns:
Returns the node that covers the location of the problem

getCoveredNode

ASTNode getCoveredNode()
Convenience method to evaluate the AST node that is covered by the current selection.

Returns:
Returns the node that is covered by the location of the problem
