Method Detail

getSequenceValue

public int getSequenceValue()

Returns the sequence value within the owning key.

Returns:

The sequence value

setSequenceValue

public void setSequenceValue(int sequenceValue)

Sets the sequence value within the owning key. Please note that you should not change the value once the reference has been added to a key.

Parameters:

sequenceValue - The sequence value

getLocalColumn

public Column getLocalColumn()

Returns the local column.

Returns:

The local column

setLocalColumn

public void setLocalColumn(Column localColumn)

Sets the local column.

Parameters:

localColumn - The local column

getForeignColumn

public Column getForeignColumn()

Returns the foreign column.

Returns:

The foreign column

setForeignColumn

public void setForeignColumn(Column foreignColumn)

Sets the foreign column.

Parameters:

foreignColumn - The foreign column
