  sysModel.env.AGlobalEnv

Direct Known Subclasses:

ASquareEnv, NoGridEnv, NullEnv, Test_AFish.TestGlobalEnv

public abstract class AGlobalEnv
extends java.lang.Object

Abstract global environment class.

Note: All subclasses must provide a two-parameter constructor that takes in an ICmdFactory for dynamic access to parse() and makeEnvFactory(), and an ISecurityAdapter for the security adapter in use.

Field Detail

OCEAN_BLUE

protected static final java.awt.Color OCEAN_BLUE

Color of the ocean.

_moveLambdas

protected LRStruct _moveLambdas

List of move commands issued. The commands issued in a fish's step are recorded so that they can be deactivated once a fish completes its step. This prevents a fish class from saving commands and executing them at a later time.

_breedLambdas

protected LRStruct _breedLambdas

List of breed commands issued. The commands issued in a fish's step are recorded so that they can be deactivated once a fish completes its step. This prevents a fish class from saving commands and executing them at a later time.

_cmdFactory

protected ICmdFactory _cmdFactory

Command factory for lambdas given to the simulation driver.

_securityManager

protected ISecurityAdapter _securityManager

Security manager that controls the actions of the fish.

_waterColor

protected java.awt.Color _waterColor

Color of the water.
