Method Detail

close

public void close()

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

Specified by:

close in interface CommandExecutor

See Also:

CommandExecutor.close()

execute

public 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.

Specified by:

execute in interface CommandExecutor

Parameters:

command - the command to be executed

Throws:

RepositorySourceException - if there is an error executing the command

See Also:

CommandExecutor.execute(org.jboss.dna.graph.commands.GraphCommand)

execute

public 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.

Specified by:

execute in interface CommandExecutor

Parameters:

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

Throws:

RepositorySourceException - if there is an error executing the command

See Also:

CommandExecutor.execute(org.jboss.dna.graph.commands.CompositeCommand)

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.

Specified by:

execute in interface CommandExecutor

Parameters:

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

Throws:

RepositorySourceException - if there is an error executing the command

See Also:

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

execute

public void execute(GetPropertiesCommand command)
             throws RepositorySourceException

Execute a command to get the properties of a node.

Specified by:

execute in interface CommandExecutor

Parameters:

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

Throws:

RepositorySourceException - if there is an error executing the command

See Also:

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

execute

public void execute(GetChildrenCommand command)
             throws RepositorySourceException

Execute a command to get the children of a node.

Specified by:

execute in interface CommandExecutor

Parameters:

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

Throws:

RepositorySourceException - if there is an error executing the command
