Method Detail

setKeysCanBeNull

public void setKeysCanBeNull(boolean keysCanBeNull)

Parameters:

keysCanBeNull - False if all keys are not null. This saves 1 byte per key if keyClass is set. True if it is not known (default).

setKeyClass

public void setKeyClass(java.lang.Class keyClass)

Parameters:

keyClass - The concrete class of each key. This saves 1 byte per key. The serializer registered for the specified class will be used. Set to null if the class is not known or varies per key (default).

setKeyClass

public void setKeyClass(java.lang.Class keyClass,
                        Serializer keySerializer)

Parameters:

keyClass - The concrete class of each key. This saves 1 byte per key. Set to null if the class is not known or varies per key (default).

keySerializer - The serializer to use for each key.

setValueClass

public void setValueClass(java.lang.Class valueClass)

Parameters:

valueClass - The concrete class of each value. This saves 1 byte per value. The serializer registered for the specified class will be used. Set to null if the class is not known or varies per value (default).

setValueClass

public void setValueClass(java.lang.Class valueClass,
                          Serializer valueSerializer)

Parameters:

valueClass - The concrete class of each value. This saves 1 byte per value. Set to null if the class is not known or varies per value (default).

valueSerializer - The serializer to use for each value.

setValuesCanBeNull

public void setValuesCanBeNull(boolean valuesCanBeNull)

Parameters:

valuesCanBeNull - True if values are not null. This saves 1 byte per value if keyClass is set. False if it is not known (default).

                            java.lang.Object object)

Description copied from class: Serializer
