Method Detail

getFirstInstant

public double getFirstInstant()

Description copied from class: Memory

Retorna o instante mais antigo em que existe informação na memória.

Specified by:

getFirstInstant in class Memory

Returns:

the first instant

getLastInstant

public double getLastInstant()

Description copied from class: Memory

Retorna o último instante em que existe informação na memória.

Specified by:

getLastInstant in class Memory

Returns:

the last instant

updateMemory

public void updateMemory()

Cleans memory beyond time horizon (past and future parameters). It always leaves the most recent event in memory, so it will never be empty.

Specified by:

readMemory in class Memory

Parameters:

instant - the instant

unit - the unit

Returns:

the object

readMemory
