* java/lang/Byte.java (static): initialize byteCache.
(valueOf(String,int)): use valueOf(byte) rather than new.
(valueOf(String)): likewise.
(valueOf(byte)): Switch from lazy initialization of cached values to
initialization at class initialization time. This removes the
need for
synchronization in the common case.
(decode): use valueOf(byte) rather than new.
* java/lang/Character.java (static): initialize charCache.
(valueOf): Switch from lazy initialization of cached values to
initialization at class initialization time. This removes the
need for
synchronization in the common case.
* java/lang/Double.java (ZERO): new private field.
(ONE): likewise.
(valueOf(double)): don't create new doubles for the case of 0 and 1.
(valueOf(String)): use valueOf(double) rather than new.
(equals): use raw bits for comparison to avoid division.
* java/lang/Float.java (ZERO): new private field.
(ONE): likewise.
(valueOf(float)): don't create new floats for the case of 0 and 1.
(valueOf(String)): use valueOf(float) rather than new.
(equals): use raw bits for comparison to avoid division.
* java/lang/Integer.java (static): initialize intCache.
(stringSize): new private method to estimate size of string for
an int.
(toString): reuse digits for single character strings, for multiple
character strings estimate their length using string size method.
(valueOf(String,int)): use valueOf(int) rather than new.
(valueOf(String)): likewise.
(valueOf(int)): Switch from lazy initialization of cached values to
initialization at class initialization time. This removes the
need for
synchronization in the common case.
(getInteger): use valueOf(int) rather than new.
(decode): use valueOf(int) rather than new.
(signum): use shift and subtract to compute value.
(toUnsignedString): calculate string size rather than using 32
chars.
* java/lang/Long.java (longCache): new private field.
(stringSize): new private method to estimate size of string for
a long.
(toString): reuse digits for single character strings, for multiple
character strings estimate their length using string size method.
(valueOf(String,int)): use valueOf(long) rather than new.
(valueOf(String)): likewise.
(valueOf(long)): use cache of values.
(decode): use valueOf(long) rather than new.
(getLong): likewise.
(signum): use shift and subtract to compute value.
(toUnsignedString): calculate string size rather than using 64
chars.
* java/lang/Short.java (static): initialize shortCache.
(valueOf(String,int)): use valueOf(short) rather than new.
(valueOf(String)): likewise.
(valueOf(short)): Switch from lazy initialization of cached
values to
initialization at class initialization time. This removes the
need for
synchronization in the common case.
(decode): use valueOf(short) rather than new.
