Constructor Detail

PythonSymlinkTree

public PythonSymlinkTree(String category,
                         BuildTarget target,
                         ProjectFilesystem filesystem,
                         Path root,
                         com.google.common.collect.ImmutableMap<Path,SourcePath> links,
                         com.google.common.collect.ImmutableSortedSet<SourcePath> directoriesToMerge,
                         SourcePathRuleFinder ruleFinder)

Creates an instance of SymlinkTree

Parameters:

category - A name used in the symlink steps

target - The target for this rule

filesystem - The filesystem that the tree lives on

root - The directory to create symlinks in

links - A map of path within the link tree to the target of the symlikm

directoriesToMerge - A map of relative paths within the link tree into which files from the value will be recursively linked. e.g. if a file at /tmp/foo/bar should be linked as /tmp/symlink-root/subdir/bar, the map should contain {Paths.get("subdir"), SourcePath(Paths.get("tmp", "foo")) }

ruleFinder - Used to iterate over directoriesToMerge in order get the build time

Method Detail

shouldDeleteExistingSymlink

protected boolean shouldDeleteExistingSymlink(ProjectFilesystem projectFilesystem,
                                              Path existingTarget)

Overrides:
