Method Summary
protected  boolean canPerformAction(org.eclipse.jface.action.IAction action, org.eclipse.jdt.core.IMember member)
          Return true if the action can be applied to the given IMember; can be overridden, but must call superclass.
protected  boolean deleteFlag(org.eclipse.jdt.core.IMember member, int flag, int flagTokenName)
          Delete modifier indicated by flag and flagTokenName using the compilation unit's buffer and an IScanner.

          Insert modifier indicated by newFlag (Flags.AccPublic) compilation unit's buffer and an IScanner.
protected abstract  boolean isChecked(org.eclipse.jface.action.IAction action, org.eclipse.jdt.core.IMember member)
          Return true if the given IMember conforms to the action modifier; subclasses must override.
protected abstract  boolean performAction(org.eclipse.jface.action.IAction action, org.eclipse.jdt.core.IMember member)
          Perform the action against the given IMember; subclasses must override.
protected  boolean replaceFlag(org.eclipse.jdt.core.IMember member, int newFlag, int replacingFlag, int replacingTokenName)
          Replace modifier indicated by replacingFlag with newFlag using the compilation unit's buffer and an IScanner.
 void run(org.eclipse.jface.action.IAction action)

Method Detail

canPerformAction

protected boolean canPerformAction(org.eclipse.jface.action.IAction action,
                                   org.eclipse.jdt.core.IMember member)
Return true if the action can be applied to the given IMember; can be overridden, but must call superclass.

deleteFlag

protected boolean deleteFlag(org.eclipse.jdt.core.IMember member,
                             int flag,
                             int flagTokenName)
Delete modifier indicated by flag and flagTokenName using the compilation unit's buffer and an IScanner. This is an example of "fine-grained" source code analysis where the context is very narrow (a member declaration). AST rewriters would be more appropriate if it were a more complex analysis.

insertFlag

protected boolean insertFlag(org.eclipse.jdt.core.IMember member,
                             int newFlag)
Insert modifier indicated by newFlag (Flags.AccPublic) compilation unit's buffer and an IScanner. This is an example of "fine-grained" source code analysis where the context is very narrow (a member declaration). AST rewriters would be more appropriate if it were a more complex analysis.

isChecked

protected abstract boolean isChecked(org.eclipse.jface.action.IAction action,
                                     org.eclipse.jdt.core.IMember member)
Return true if the given IMember conforms to the action modifier; subclasses must override.

performAction

protected abstract boolean performAction(org.eclipse.jface.action.IAction action,
                                         org.eclipse.jdt.core.IMember member)
Perform the action against the given IMember; subclasses must override.

replaceFlag

protected boolean replaceFlag(org.eclipse.jdt.core.IMember member,
                              int newFlag,
                              int replacingFlag,
                              int replacingTokenName)
Replace modifier indicated by replacingFlag with newFlag using the compilation unit's buffer and an IScanner. This is an example of "fine-grained" source code analysis where the context is very narrow (a member declaration). AST rewriters would be more appropriate if it were a more complex analysis.

run

public void run(org.eclipse.jface.action.IAction action)
Delegate the processing of the run action to subclasses.

Specified by:
run in interface org.eclipse.ui.IActionDelegate

selectionChanged

public void selectionChanged(org.eclipse.jface.action.IAction action,
                             org.eclipse.jface.viewers.ISelection selection)
Determine if the current action applies to the IMembers, given their current state. If the selection is homogeneous, also check the action if all conform to this action's modifier.

Specified by:
selectionChanged in interface org.eclipse.ui.IActionDelegate
