Method Detail

allocate

Allocation allocate()

Obtain an Allocation.

When the caller has finished with the Allocation, it should be returned by calling release(Allocation).

Returns:

The Allocation.

release

void release(Allocation allocation)

Return an Allocation.

Parameters:

allocation - The Allocation being returned.

release

void release(Allocation[] allocations)

Return an array of Allocations.

Parameters:

allocations - The array of Allocations being returned.

trim

void trim(int targetSize)

Hints to the Allocator that it should make a best effort to release any memory that it has allocated, beyond the specified target number of bytes.

Parameters:

targetSize - The target size in bytes.

blockWhileTotalBytesAllocatedExceeds

void blockWhileTotalBytesAllocatedExceeds(int limit)
                                   throws InterruptedException

Blocks execution until the number of bytes allocated is not greater than the limit, or the thread is interrupted.

Parameters:

limit - The limit in bytes.

Throws:

InterruptedException - If the thread is interrupted.

getTotalBytesAllocated

int getTotalBytesAllocated()

Returns the total number of bytes currently allocated.

getIndividualAllocationLength

int getIndividualAllocationLength()

Returns the length of each individual Allocation.
