Field Summary

Fields

Modifier and Type	Field and Description
static String	PROP_INITIAL_LENGTH Property name used to control the initial length (in UTF-8 encoded bytes) of strings created by a factory.
static String	PROP_NATIVE Property name used to control whether or not strings created by a factory are backed by native buffers.
static String	PROP_POOL_PREALLOCATE_COUNT Property indicating whether or not the pool backing the factory should preallocate XStrings to avoid object promotion at runtime.
static String	PROP_POOL_THREADED Property indicating whether or not the pool backing the factory is a thread safe.

Field Detail

PROP_INITIAL_LENGTH

static final String PROP_INITIAL_LENGTH

Property name used to control the initial length (in UTF-8 encoded bytes) of strings created by a factory.

Specifying a value of 0 will cause no backing buffer for the XString to be preallocated which can be useful for preventing object promotions at runtime.

If the XString is later initialized to a value large than the specified initial length a new backing buffer will be allocated to accommodate the larger size.

PROP_NATIVE

static final String PROP_NATIVE

Property name used to control whether or not strings created by a factory are backed by native buffers.

Constant Field Values

PROP_POOLED

static final String PROP_POOLED

Property indicating whether or not the factory is backed by a pool.

This Property applies to XString.Factorys for XString subclasses that support pooling.

Constant Field Values

PROP_POOL_THREADED

static final String PROP_POOL_THREADED

Property indicating whether or not the pool backing the factory is a thread safe.

This Property applies to XString.Factorys for XString subclasses that support pooling or preallocation.

Constant Field Values

PROP_POOL_PREALLOCATE_COUNT

static final String PROP_POOL_PREALLOCATE_COUNT

Property indicating whether or not the pool backing the factory should preallocate XStrings to avoid object promotion at runtime.

This Property only applies to XString.Factorys for XString subclasses that support preallocation

Method Detail

create

T create()

Returns an empty, mutable XString possibly from a backing pool. When the the user is done with the XString, dispose() should be called if the the XString is a poolable type, to return the object to the pool.

Returns:

An uninitialized XString.

createArray

T[] createArray(int size)

Parameters:

size - the size of the array to create

Returns:

A mutable array of uninitialized strings.

create

T create(boolean mutable)

Returns an empty XString possibly from a backing pool. When the the user is done with the XString, dispose() should be called if the the XString is a poolable type, to return the object to the pool.

Parameters:

mutable - Whether or not the XString supports mutation (after it is first set)

Returns:

An uninitialized XString.

create

T create(String value)

Creates an immutable XString, possibly from a backing pool, from the given String value. When the the user is done with the XString, dispose() should be called if the the XString is a poolable type, to return the object to the pool.

Parameters:

value - The string value to assign to the XString.

Returns:

An initialized XString

create

T create(String initialValue,
         boolean mutable)

Creates an XString possibly from a backing pool. When the the user is done with the XString, dispose() should be called if the the XString is a poolable type, to return the object to the pool.

Parameters:

initialValue - The string value to assign to the XString.

mutable - Whether or not the XString supports mutation.

Returns:

An initialized XString

create

T create(XString initialValue,
         boolean mutable)

Creates an XString possibly from a backing pool. When the the user is done with the XString, dispose() should be called if the the XString is a poolable type, to return the object to the pool.

Parameters:

initialValue - The string value to assign to the XString.

mutable - Whether or not the XString supports mutation.

Returns:

An initialized XString.
