Constant Field Values

arrayLength

private final int arrayLength

The actual length of the char-arrays.

Constructor Detail

CharArrayPoolImpl

public CharArrayPoolImpl()

The constructor.

CharArrayPoolImpl

public CharArrayPoolImpl(int capacity,
                         int arrayLength)

The constructor.

Parameters:

capacity - is the capacity of the pool.

arrayLength - is the length of each pooled byte-array.

Method Detail

create

protected char[] create()

This method creates a new element. It is used if there is no instance left in the pool.

Specified by:

create in class AbstractPool<char[]>

Returns:

the new instance.

reset

protected boolean reset(char[] element)

This method resets the given element so it can be reused. It is called if an element is released and will be stored in the pool. The implementation depends on the type of element. Some types may become inconsistent if they are directly reused. Further this method may clear data from the element for security reasons, because the same instance may be given to some other component that is NOT trusted enough (because it may be vulnerably).

Overrides:

reset in class AbstractPool<char[]>

Parameters:

element - the element to reset.

Returns:

true if the given element can be reused and should be added to the pool, false otherwise.
