A branch specification ('spec') is a named, user-defined mapping of
depot files to depot files. It can be used with most of the commands
that operate on two sets of files ('copy', 'merge', 'integrate',
'diff2', etc.)

Creating a branch spec does not branch files. To branch files, use
'p4 copy', with or without a branch spec.

The 'branch' command puts the branch spec into a temporary file and
invokes the editor configured by the environment variable $P4EDITOR.
Saving the file creates or modifies the branch spec.

The branch spec contains the following fields:

Branch: The branch spec name (read only).

Owner: The user who created this branch spec. Can be changed.

Update: The date this branch spec was last modified.

Access: The date of the last command used with this spec.

Description: A description of the branch spec (optional).

Options: Flags to change the branch spec behavior. The defaults
are marked with *.

locked Permits only the owner to change the spec.
unlocked * Prevents the branch spec from being deleted.

View: Lines mapping of one view of depot files to another.
Both the left and right-hand sides of the mappings refer
to the depot namespace. See 'p4 help views' for more on
view syntax.

New branch specs are created with a default view that maps all depot
files to themselves. This view must be changed before the branch
spec can be saved.

The -d flag deletes the named branch spec.

The -o flag writes the branch spec to standard output. The user's
editor is not invoked.

The -i flag causes a branch spec to be read from the standard input.
The user's editor is not invoked.

The -f flag enables a user with 'admin' privilege to delete the spec
or set the 'last modified' date. By default, specs can be deleted
only by their owner.

A branch spec can also be used to expose the internally generated
mapping of a stream to its parent. (See 'p4 help stream' and 'p4
help streamintro'.)

The -S stream flag will expose the internally generated mapping.
The -P flag may be used with -S to treat the stream as if it were a
child of a different parent. The -o flag is required with -S.

Examples
To create a branch spec [-i]:
Copy
BranchSpec newBranchSpec = new BranchSpec();
newBranchSpec.Id = "newBranchSpec";
newBranchSpec.Owner = "admin";
newBranchSpec.Description = " created by perforce";
newBranchSpec.ViewMap = new ViewMap();
string v0 = "//depot/main/... //depot/rel1/...";
string v1 = "//depot/main/... //depot/rel2/...";
string v2 = "//depot/dev/... //depot/main/...";
newBranchSpec.ViewMap.Add(v0);
newBranchSpec.ViewMap.Add(v1);
newBranchSpec.ViewMap.Add(v2);
Options opts = new Options(BranchSpecCmdFlags.Input);
_repository.CreateBranchSpec(newBranchSpec, opts);
