Examples of org.apache.derby.impl.io.vfmem.VirtualFile.mkdir()

org.apache.derby.impl.io.vfmem.VirtualFile.mkdir()
Creates the directory denoted by this virtual file if it doesn't exist.
For the directory to be created, it cannot exist already (either as a file or a directory), and any parent directories must exist. @return {@code true} if the directory was created, {@code false}otherwise.
