public class FSTTypedStructAllocator<T extends FSTStruct>
extends FSTStructAllocator

An extension of FSTStructAllocaor to ease pools of specific objects. A template (for new allocs) instance is associated with this allocator instance. Created with IntelliJ IDEA. User: ruedi Date: 23.07.13 Time: 18:20 To change this template use File | Settings | File Templates.

Constructor Detail

FSTTypedStructAllocator

public FSTTypedStructAllocator(T ontpl)

Create a Structallocator for the given template. Chunksize will be set to the size of one template struct, so with each strutc allocation an individual byte array is created behind the scenes

Parameters:

ontpl -

FSTTypedStructAllocator

public FSTTypedStructAllocator(T ontpl,
                               int objectsPerChunk)

Create a Structallocator for the given template. Chunksize will be set to contain 'objectsPerChunk' instances of the given struct template.

Parameters:

ontpl -

objectsPerChunk -

FSTTypedStructAllocator

public FSTTypedStructAllocator(T ontpl,
                               int objectsPerChunk,
                               BytezAllocator alloc)

Create a Structallocator for the given template. Chunksize will be set to contain 'objectsPerChunk' instances of the given struct template.

Parameters:

ontpl -

objectsPerChunk -

FSTTypedStructAllocator

public FSTTypedStructAllocator(int chunkSizeBytes,
                               T template)

Create a Structallocator for the given template. Chunksize will be set directly

Parameters:

template -

chunkSizeBytes -

FSTTypedStructAllocator

public FSTTypedStructAllocator(int chunkSizeBytes,
                               T template,
                               BytezAllocator alloc)

see super class ..

Parameters:

chunkSizeBytes -

template -

alloc -

Method Detail

newArray

public StructArray<T> newArray(int size)

create a new struct array of same type as template

Parameters:

size -

Returns:

newMap

public <K extends FSTStruct> StructMap<K,T> newMap(int size,
                                                   K keyTemplate)

create a fixed size struct hashmap. Note it should be of fixed types for keys and values, as the space for those is allocated directly. Additionally keys and values are stored 'in-place' without references.

Type Parameters:

K -

Parameters:

size -

keyTemplate -

Returns:

newStruct

public T newStruct()

getTemplateSize

public int getTemplateSize()
