Method Summary

void	close() Close this executor, allowing it to clean up any open resources.
void	execute(CopyBranchCommand command) Execute a command to copy an entire branch to a new location.
void	execute(CopyNodeCommand command) Execute a command to copy a node to a new location.
void	execute(CreateNodeCommand command) Execute a command to create a node and set the node's properties.
void	execute(DeleteBranchCommand command) Execute a command to delete an entire branch.
void	execute(GetChildrenCommand command) Execute a command to get the children of a node.
void	execute(GetNodeCommand command) 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 CommandExecutor.execute(GetPropertiesCommand) and CommandExecutor.execute(GetChildrenCommand) methods. This method implementation simply delegates to both the AbstractCommandExecutor.execute(GetPropertiesCommand) and AbstractCommandExecutor.execute(GetChildrenCommand) methods, and should be overridden by subclasses that can process GetNodeCommand more efficiently as a single command.
void	execute(GetPropertiesCommand command) Execute a command to get the properties of a node.
void	execute(MoveBranchCommand command) Execute a command to move a branch from one location to another.
void	execute(RecordBranchCommand command) Execute a command to record the structure of a branch.
void	execute(SetPropertiesCommand command) Execute a command to set some (or all) of the properties on a node.

Constructor Detail

SingleProjectionCommandExecutor

public SingleProjectionCommandExecutor(ExecutionContext context,
                                       String sourceName,
                                       Projection projection,
                                       RepositoryConnectionFactory connectionFactory)

Parameters:

context - the execution context in which the executor will be run; may not be null

sourceName - the name of the RepositorySource that is making use of this executor; may not be null or empty

projection - the projection used for the cached information; may not be null and must have exactly one rule

connectionFactory - the factory for RepositoryConnection instances

SingleProjectionCommandExecutor

public SingleProjectionCommandExecutor(ExecutionContext context,
                                       String sourceName,

                                       RepositoryConnectionFactory connectionFactory)

Parameters:

context - the execution context in which the executor will be run; may not be null

sourceName - the name of the RepositorySource that is making use of this executor; may not be null or empty

now - the current time; may be null if the system time is to be used

projection - the projection used for the cached information; may not be null and must have exactly one rule

connectionFactory - the factory for RepositoryConnection instances

Method Detail

close

public void close()

Close this executor, allowing it to clean up any open resources.

Specified by:

close in interface CommandExecutor

Overrides:

close in class AbstractCommandExecutor

See Also:

AbstractCommandExecutor.close()

execute

public void execute(GetChildrenCommand command)
             throws RepositorySourceException

Execute a command to get the children of a node.

Specified by:

execute in interface CommandExecutor

Overrides:

execute in class AbstractCommandExecutor

Parameters:

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

Throws:

RepositorySourceException - if there is an error executing the command

See Also:

AbstractCommandExecutor.execute(org.jboss.dna.graph.commands.GetChildrenCommand)

execute

public void execute(GetPropertiesCommand command)
             throws RepositorySourceException

Execute a command to get the properties of a node.

Specified by:

execute in interface CommandExecutor

Overrides:

execute in class AbstractCommandExecutor

Parameters:

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

Throws:

RepositorySourceException - if there is an error executing the command

See Also:

AbstractCommandExecutor.execute(org.jboss.dna.graph.commands.GetPropertiesCommand)

execute

public 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 CommandExecutor.execute(GetPropertiesCommand) and CommandExecutor.execute(GetChildrenCommand) methods.

This method implementation simply delegates to both the AbstractCommandExecutor.execute(GetPropertiesCommand) and AbstractCommandExecutor.execute(GetChildrenCommand) methods, and should be overridden by subclasses that can process GetNodeCommand more efficiently as a single command.

Specified by:

execute in interface CommandExecutor

Overrides:

execute in class AbstractCommandExecutor

Parameters:

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

Throws:

RepositorySourceException - if there is an error executing the command

See Also:

AbstractCommandExecutor.execute(org.jboss.dna.graph.commands.GetNodeCommand)

execute

public void execute(CreateNodeCommand command)
             throws RepositorySourceException

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

Specified by:

Overrides:

execute in class AbstractCommandExecutor

Parameters:

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

Throws:

RepositorySourceException - if there is an error executing the command

See Also:

AbstractCommandExecutor.execute(org.jboss.dna.graph.commands.CreateNodeCommand)

execute

public void execute(SetPropertiesCommand command)
