Method Detail

execute

void execute(GraphCommand command)
             throws RepositorySourceException

Execute a graph command. This method should examine the command's types to determine which other execute methods should be called, and should then call those methods. This method should also do nothing if the command is null.

Parameters:

command - the command to be executed

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(CompositeCommand command)
             throws RepositorySourceException

Execute a composite command that contains other commands. This method should simply obtain and execute each of the nested commands.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(GetNodeCommand command)
             throws RepositorySourceException

Execute a command to get the properties and children of a node. GetNodeCommand is a subtype of both GetPropertiesCommand and GetChildrenCommand, so this method will be called in place of the execute(GetPropertiesCommand) and execute(GetChildrenCommand) methods.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(GetPropertiesCommand command)
             throws RepositorySourceException

Execute a command to get the properties of a node.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(GetChildrenCommand command)
             throws RepositorySourceException

Execute a command to get the children of a node.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(CreateNodeCommand command)
             throws RepositorySourceException

Execute a command to create a node and set the node's properties.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(SetPropertiesCommand command)
             throws RepositorySourceException

Execute a command to set some (or all) of the properties on a node.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(CopyNodeCommand command)
             throws RepositorySourceException

Execute a command to copy a node to a new location.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(CopyBranchCommand command)
             throws RepositorySourceException

Execute a command to copy an entire branch to a new location.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(RecordBranchCommand command)
             throws RepositorySourceException

Execute a command to record the structure of a branch.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(DeleteBranchCommand command)
             throws RepositorySourceException

Execute a command to delete an entire branch.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

execute

void execute(MoveBranchCommand command)
             throws RepositorySourceException

Execute a command to move a branch from one location to another.

Parameters:

command - the command to be executed; may not be null

Throws:

RepositorySourceException - if there is an error executing the command

close

void close()
