Field Detail

NAMESPACE_NAME

public static final String NAMESPACE_NAME

The name of the namespace that this class implements.

See Also:

Constant Field Values

mNamespace

protected String mNamespace

The name of the implementing namespace. It should be one of the valid namespaces always.

See Also:

Namespace.isNamespaceValid(String)

Constructor Detail

Stat

public Stat()

The default constructor. Note that the map is not allocated memory at this stage. It is done so in the overloaded construct function.

Stat

public Stat(Map mp)

The overloaded constructor.

Parameters:

mp - map (possibly empty).

Method Detail

get

public Object get(Object key)

Returns the value to which this namespace maps the specified key. Returns null if the map contains no mapping for this key. A return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.

Overrides:

get in class Namespace

Parameters:

key - The key whose value you want.

namespaceName

public String namespaceName()

Returns the name of the namespace associated with the profile implementations.

Specified by:

namespaceName in class Namespace

Returns:

the namespace name.

See Also:

NAMESPACE_NAME

construct

public void construct(String key,
                      String value)

Constructs a new element of the format (key=value). It first checks if the map has been initialised or not. If not then allocates memory first.

Overrides:

construct in class Namespace

Parameters:

key - is the left-hand-side

value - is the right hand side

checkKey

public int checkKey(String key,
                    String value)

This checks whether the key passed by the user is valid in the current namespace or not. At present, for this namespace all the keys are construed as valid as long as the value passed is not null.

Specified by:

checkKey in class Namespace

Parameters:

key - (left hand side)

value - (right hand side)

Returns:

Namespace.VALID_KEY

checkKeyInNS

public void checkKeyInNS(PegasusProperties properties,
                         String pool)

It puts in the namespace specific information specified in the properties file into the namespace. The name of the pool is also passed, as many of the properties specified in the properties file are on a per pool basis.

Specified by:

checkKeyInNS in class Namespace

Parameters:

properties - the PegasusProperties object containing all the properties that the user specified at various places (like .chimerarc, properties file, command line).

pool - the pool name where the job is scheduled to run.

checkKeyInNS

public void checkKeyInNS(String envString)

It takes in key=value pairs separated by a ; and puts them into the namespace after checking if they are valid or not.

Parameters:

envString - the String containing the environment variables and their values separated by a semi colon.

merge

public void merge(Namespace profiles)

Merge the profiles in the namespace in a controlled manner. In case of intersection, the new profile value overrides, the existing profile value.

Specified by:

merge in class Namespace

Parameters:

profiles - the Namespace object containing the profiles.

toCondor

public String toCondor()

Converts the contents of the map into the string that can be put in the Condor file for printing.

Specified by:

toCondor in class Namespace

Returns:

the textual description.

clone

public Object clone()

Returns a copy of the current namespace object.

Overrides:

clone in class Namespace

Returns:

the Cloned object
