Constructor Detail

PartialRequestEntry

public PartialRequestEntry(long recordIndex,
                   int fieldIndex,
                   IBuffer.TransportOverride override,
                   Object notify)

Creates a new instance for the request based on its details

Parameters:

recordIndex - The Record index

fieldIndex - The Field index

override - The IBuffer.TransportOverride directive

notify - The synchronization object to use to notify the requester

Method Detail

getRecordIndex

public long getRecordIndex()

Retrieved the Record index

Returns:

the Record index

setRecordIndex

public void setRecordIndex(long recordIndex)

Sets the Record index

Parameters:

recordIndex - the Record index

getFieldIndex

public int getFieldIndex()

Retrieved the Field index

Returns:

the Field index

setFieldIndex

public void setFieldIndex(int fieldIndex)

Sets the Field index

Parameters:

fieldIndex - the Field index

getNotify

public Object getNotify()

Retrieves the synchronization object

Returns:

the synchronization object

setNotify

public void setNotify(Object notify)

Sets the synchronization object

Parameters:

notify - the synchronization object

getOverride

public IBuffer.TransportOverride getOverride()

Retrieves the IBuffer.TransportOverride directive

Returns:

the IBuffer.TransportOverride directive

setOverride

public void setOverride(IBuffer.TransportOverride override)

Sets the IBuffer.TransportOverride directive

Parameters:

override - the IBuffer.TransportOverride directive

equals

public boolean equals(Object obj)

the equality operation is based in the Record index and the Field index

Overrides:

equals in class Object

See Also:

Object.equals(java.lang.Object)

copy

public PartialRequestEntry copy()

Creates a new instance of the PartialRequestEntry with the same values as the ones available in this instance

Returns:

the new instance

hashCode

public int hashCode()

Since the two key values used for equality are the Record and Field index, the hash code created is based in the Cantor function to create a unique hash value

Overrides:

hashCode in class Object
