Method Details

put

@Deprecated
<T> void put(T array,
 Class<T> arrayClass)

Deprecated.

Use put(Object)

Optionally adds the given array of the given type to the pool.

Arrays may be ignored, for example if the array is larger than the maximum size of the pool.

put

<T> void put(T array)

Optionally adds the given array of the given type to the pool.

Arrays may be ignored, for example if the array is larger than the maximum size of the pool.

get

<T> T get(int size,
 Class<T> arrayClass)

Returns a non-null array of the given type with a length >= to the given size.

If an array of the given size isn't in the pool, a new one will be allocated.

This class makes no guarantees about the contents of the returned array.

• getExact(int, Class)

getExact

<T> T getExact(int size,
 Class<T> arrayClass)

Returns a non-null array of the given type with a length exactly equal to the given size.

If an array of the given size isn't in the pool, a new one will be allocated.

This class makes no guarantees about the contents of the returned array.

• get(int, Class)

clearMemory

void clearMemory()

Clears all arrays from the pool.

trimMemory

void trimMemory(int level)

Trims the size to the appropriate level.

Parameters:

level - A trim specified in ComponentCallbacks2.
