ScmCommandBuilder

implements CommandBuilder<B extends CommandBuilder<B>>

com.atlassian.stash.scm.ScmCommandBuilder<B extends com.atlassian.stash.scm.ScmCommandBuilder<B>>

Class Overview

Augments the CommandBuilder with SCM-related properties, still supporting creating free-form commands. SCM command builders are specifically intended to be used with binaries such as git, hg or svn, which provide a variety of different commands, each accepting different arguments and input and producing different output, to carry out their functionality.

Summary

Public Methods
@Nonnull <T> Command<T>	build(CommandOutputHandler<T> outputHandler) Builds a `Command` which, when `executed`, will provide output to the provided `outputHandler` for processing.
@Nonnull B	command(String command) Sets the command to execute.

Inherited Methods

From interface com.atlassian.stash.scm.CommandBuilder

@Nonnull B	argument(String argument) Appends the provided argument.
@Nonnull B	argumentAfter(String anchor, String argument) Inserts the provided argument immediately after the specified anchor, if the anchor can be found.
@Nonnull B	argumentAt(int index, String argument) Inserts the provided argument at the specified index.
@Nonnull B	argumentBefore(String anchor, String argument) Inserts the provided argument immediately before the specified anchor, if the anchor can be found.
@Nonnull B	clearArguments() Clears any arguments which have been set.
@Nonnull B	clearInputHandler() Clears the `input handler`, if one has been set.
@Nonnull B	defaultErrorHandler() Applies the default `error handler`, which will collect any output written to the error stream and provide that output to the `exit handler`.
@Nonnull B	errorHandler(CommandErrorHandler value) Sets the `error handler` which will be used to process any output written to the error stream as the command runs.
@Nonnull B	inputHandler(CommandInputHandler value) Sets the `input handler` which will be used to feed data to the command's input stream.

@Nonnull <T> Command<T>	build(CommandOutputHandler<T> outputHandler) Builds a `Command` which, when `executed`, will provide output to the provided `outputHandler` for processing.
@Nonnull B	clearEnvironment() Clears any environment variables which have been set.
@Nonnull B	defaultExitHandler() Applies the default `CommandExitHandler`.
@Nonnull B	defaultWorkingDirectory() Applies the default working directory, which is the working directory for the current Java process.
@Nonnull B	environment(String name, String value) Adds an environment variable with the specified `name` and `value`.
@Nonnull B	exitHandler(CommandExitHandler value) Sets the `CommandExitHandler` which should be invoked after the command exits.
@Nonnull B	workingDirectory(File value) Sets the working directory which should be used when the command is run.
@Nonnull B	workingDirectory(String value) Sets the working directory which should be used when the command is run.

Public Methods

@Nonnull public Command<T> build (CommandOutputHandler<T> outputHandler)

Builds a Command which, when executed, will provide output to the provided outputHandler for processing.

If no command has been set, the first argument is assumed to be the command. For SCMs with unified binaries that have no default command, if no command has been set and no arguments have been provided, implementations may throw an exception rather than executing the process which, most likely, will simply print usage information and exit.

Parameters

outputHandler	the handler to receive and process output from the command as it executes

Returns

the built command

Throws

IllegalStateException	if no command has been set and no arguments were provided
NullPointerException	if the provided `outputHandler` is `null`

@Nonnull public B command (String command)

Sets the command to execute.

Most SCMs, such as git, hg or svn, have a single unified binary which expects the command to run as its first argument. This property separates that special command argument from the others, allowing other arguments to be cleared without clearing the command as well.

Parameters

command	the SCM command to execute

Returns

this

Throws

IllegalArgumentException	if the provided `command` is empty or blank
NullPointerException	if the provided `command` is `null`
