Constructor Detail

BasicScope

@ConstructorProperties(value="")
public BasicScope()

Creates unnamed scope

BasicScope

@ConstructorProperties(value={"parent","type","name","persistent"})
public BasicScope(IScope parent,
                                     ScopeType type,
                                     String name,
                                     boolean persistent)

Constructor for basic scope

Parameters:

parent - Parent scope

type - Scope type

name - Scope name. Used to identify scopes in application, must be unique among scopes of one level

persistent - Whether scope is persistent

Method Detail

hasParent

public boolean hasParent()

Does this scope have a parent? You can think of scopes as of tree items where scope may have a parent and children (child).

Specified by:

hasParent in interface IBasicScope

Returns:

true if this scope has a parent, otherwise false

getParent

public IScope getParent()

Get this scopes parent.

Specified by:

getParent in interface IBasicScope

Returns:

parent scope, or null if this scope doesn't have a parent

getType

public ScopeType getType()

Description copied from interface: IBasicScope

Get the type of the scope.

Specified by:

getType in interface IBasicScope

Returns:

the type

getName

public String getName()

Description copied from interface: IBasicScope

Get the name of this scope. Eg. someroom.

Specified by:

getName in interface IBasicScope

Returns:

the name

getStore

public IPersistenceStore getStore()

Description copied from interface: IBasicScope

Get the persistable store

Specified by:

getStore in interface IBasicScope

Returns:

the store

getDepth

public int getDepth()

Get the scopes depth, how far down the scope tree is it. The lowest depth is 0x00, the depth of Global scope. Application scope depth is 0x01. Room depth is 0x02, 0x03 and so forth.

Specified by:

getDepth in interface IBasicScope

Returns:

the depth

getPath

Sets the amount of time to keep the scope available after the last disconnect.

Specified by:

setKeepDelay in interface IBasicScope

Parameters:

keepDelay - delay

isValid

public boolean isValid()

Validates a scope based on its name and type

Specified by:

isValid in interface IBasicScope
