Method Detail

isWritable

boolean isWritable()

Return whether the contents of this resource can be modified, e.g. via getOutputStream() or Resource.getFile().

Will be true for typical resource descriptors; note that actual content writing may still fail when attempted. However, a value of false is a definitive indication that the resource content cannot be modified.
