Hi.

I have my own implementation of IResourceChangeListener, which recognizes
when file was moved and then makes some modifications to i's content. But
when I try to save this modified content to file using IFile.setContent(),
i get the following exception:

org.eclipse.core.internal.resources.ResourceException: The resource tree
is locked for modifications.
at
org.eclipse.core.internal.resources.WorkManager.checkIn(Work Manager.java:115)
at
org.eclipse.core.internal.resources.Workspace.prepareOperati on(Workspace.java:1747)
at org.eclipse.core.internal.resources.File.setContents(File.ja va:364)
at org.eclipse.core.internal.resources.File.setContents(File.ja va:469)

I understand that I cannot modify file's content while processing resource
delta. So I need someway to delay this modifaction. Is there a standart
way to do this (maybe some queue, which accepts runnables, and then exutes
them in batch after processing whole resource delta and unlocking resource
tree) or I have to write my own implementation for this operation?

Thanks.
