Method Detail

get

public float get()
Returns the current value of the var.

Returns:
The current value.

add

public float add(float x)
Adds the given value to this var and returns the result.

Parameters:
x - The value to add to this var.
Returns:
The result of the operation.

max

public float max(float x)
Sets the var to the max between this var and the value.

Parameters:
x - The value to take the max of with this var.
Returns:
The result of the operation.

min

Parameters:
x - The value to multiply by this var.
Returns:
The result of the operation.

set

public void set(float value)
Sets the value of this var, but does not write it to the store.

Parameters:
value - The new value.

put

public void put(float value)
Sets the value of this var and writes it to the store.

Parameters:
value - The new value.

take

public float take()
Returns the value of this var by first reading it from the store.

Returns:
The value of this var.

getValue

public java.lang.Float getValue()
Returns the value of this var as it was the last time this variable was read from a store at the location (and maybe with an offset) or as it was set with the setValue method.

Returns:
The last value read.

setValue

public void setValue(java.lang.Float value)
Sets the value of this var without writing the value to a store.

Parameters:
value - The new value to set.

onRead

public void onRead(int location,
                   Store store)
Reads this data from the given store at the given location.
