readProperties

public void readProperties(Properties properties)

Description copied from interface: PropertyFileHandle

Reads the file associated with this handle and will do the following:

• Add any type found not previously added by this handle
• Add any instance found not previously added by this handle
• Modify any property that has changed value
• Remove any instance no longer seen in the file but that had previously been added
In particular this method will NOT remove a type that was previously added but which has no more instances (other files may be contributing to the same type). After reaching the end of the input stream this method will close it

Specified by:

readProperties in interface PropertyFileHandle

Parameters:

properties - The properties object to inspect. May not be null

getTypes

private static HashSet<String> getTypes(HashMap<PropertyFileHandleImpl.TypeData, Map<String,String>> lastRead)

getInstances

private static HashSet<String> getInstances(String typeName,
 HashMap<PropertyFileHandleImpl.TypeData, Map<String,String>> lastRead)

getSpecificType

public String getSpecificType()

Description copied from interface: PropertyFileHandle

Returns the specific type associated with this handle

Specified by:

getSpecificType in interface PropertyFileHandle

Returns:

The specific type this handle is updating. May return null if this is a multi-type handle

getDefaultType

public String getDefaultType()

Description copied from interface: PropertyFileHandle

Returns the default type name if the type cannot be determined from the key of the property. Will return null if getSpecificType is not null

Specified by:

getDefaultType in interface PropertyFileHandle

Returns:

The default type name if the type cannot be determined, or null if this handle has a specific type

getDefaultInstanceName

public String getDefaultInstanceName()

Description copied from interface: PropertyFileHandle

Gets the default instance name that will be given to instances whose name cannot otherwise be determined

Specified by:

getDefaultInstanceName in interface PropertyFileHandle

Returns:

The default instance name. Will not return null

dispose

public void dispose()

Description copied from interface: PropertyFileHandle

Will remove any instances added by this handle from the hub, and make it such that this handle can no longer be used

Specified by:

dispose in interface PropertyFileHandle
