Method Detail

iterator

public java.util.Iterator iterator()

Description copied from interface: DataCollection

Returns an iterator over the data elements in this collection. There are no guarantees concerning the order in which the elements are returned. If the data collection is modified while an iteration over it is in progress, the results of the iteration are undefined.

To do:

Document

contains

public boolean contains(java.lang.String name)

Description copied from class: AbstractDataCollection

Returns true if this data collection contains the element with specified name.

Specified by:

contains in interface DataCollection

Overrides:

contains in class AbstractDataCollection

Parameters:

name - name of element whose presence in this data collection is to be tested.

Returns:

true if this data collection contains the element with specified name.

See Also:

AbstractDataCollection.contains(ru.biosoft.access.DataElement)

To do:

Document

getSize

public int getSize()

Description copied from class: AbstractDataCollection

Gets size of data collection. This method must be overrided for perfomance improving.

Specified by:

getSize in interface DataCollection

Overrides:

getSize in class AbstractDataCollection

Returns:

Number of data element in this data collection.

To do:

Document

getInternalNameList

public java.util.List getInternalNameList()

getNameList

public java.util.List getNameList()

Description copied from class: AbstractDataCollection

Gets list of all names in data collection.

Specified by:

getNameList in interface DataCollection

Overrides:

getNameList in class AbstractDataCollection

Returns:

Names of all elements in the data collection.

isMutable

public boolean isMutable()

Determine is this collection mutable (writable).

Specified by:

isMutable in interface DataCollection

Overrides:

isMutable in class AbstractDataCollection

Returns:

Always return TRUE.

close

public void close()
           throws java.lang.Exception

Close data collection. Release all resources (data file and index file). After call this method collection is invalid and any other methods may throw exceptions.

Specified by:

close in interface DataCollection

Overrides:

close in class AbstractDataCollection

Throws:

java.lang.Exception - If error occured.

doGet

protected DataElement doGet(java.lang.String name)
                     throws java.lang.Exception

Description copied from class: AbstractDataCollection

This method should be implemented in subclasses to get the specified data element from the collection. This implementation use iterator for finding needed data element.

Overrides:

doGet in class AbstractDataCollection

Parameters:

name - Name of needed data element.

Returns:

Data element or null if data element with specified name not found.

Throws:

java.lang.Exception

See Also:

AbstractDataCollection.get(String), DataCollection.iterator()

To do:

Document, high Optimize with other Entry constructor.

doPut

protected void doPut(DataElement element,
                     boolean isNew)
              throws java.lang.Exception

Description copied from class: AbstractDataCollection

This method should be implemented in mutable subclasses to put the specified data element into the collection.

Overrides:

doPut in class AbstractDataCollection

Throws:

java.lang.Exception

See Also:

AbstractDataCollection.put(DataElement)

To do:

Document

doRemove

protected void doRemove(java.lang.String name)
                 throws java.lang.Exception

Description copied from class: AbstractDataCollection

This method should be implemented in mutable subclasses to remove the specified data element from the collection.

Overrides:

doRemove in class AbstractDataCollection

Throws:

java.lang.Exception

See Also:

AbstractDataCollection.remove(String)

To do:

Document, do not write data to the file, only start shars,key,"delete",end chars, Rewrite (now this code pasted from old FileEntryCollection)
