Long

Constructors

this this(long value): Constructs a newly allocated {@code Long} object that represents the specified {@code long} argument.
this this(string s): Constructs a newly allocated {@code Long} object that represents the {@code long} value indicated by the {@code string} parameter. The string is converted to a {@code long} value in exactly the manner used by the {@code parseLong} method for radix 10.

Functions

opCmp int opCmp(Object o): Undocumented in source. Be warned that the author may not have intended to support it.
opCmp int opCmp(long n): Undocumented in source. Be warned that the author may not have intended to support it.
toHash size_t toHash(): Returns a hash code for a {@code long} value; compatible with {@code Long.hashCode()}.

Manifest constants

BYTES enum BYTES;: The number of bytes used to represent a {@code long} value in two's complement binary form.

Static functions

bitCount int bitCount(long i): Returns the number of one-bits in the two's complement binary representation of the specified {@code long} value. This function is sometimes referred to as the population count.
formatUnsignedLong int formatUnsignedLong(long val, int shift, char[] buf, int offset, int len): Format a long (treated as unsigned) into a character buffer. @param val the unsigned long to format @param shift the log2 of the base to format in (4 for hex, 3 for octal, 1 for binary) @param buf the character buffer to write to @param offset the offset in the destination buffer to start at @param len the number of characters to write @return the lowest character location used
numberOfLeadingZeros int numberOfLeadingZeros(long i): Returns the number of zero bits preceding the highest-order ("leftmost") one-bit in the two's complement binary representation of the specified {@code long} value. Returns 64 if the specified value has no one-bits in its two's complement representation, in other words if it is equal to zero.
numberOfTrailingZeros int numberOfTrailingZeros(long i): Returns the number of zero bits following the lowest-order ("rightmost") one-bit in the two's complement binary representation of the specified {@code long} value. Returns 64 if the specified value has no one-bits in its two's complement representation, in other words if it is equal to zero.
parseLong long parseLong(string s, int radix): Undocumented in source. Be warned that the author may not have intended to support it.
signum int signum(long i): Returns the signum function of the specified {@code long} value. (The return value is -1 if the specified value is negative; 0 if the specified value is zero; and 1 if the specified value is positive.)
toBinaryString string toBinaryString(long i): Returns a string representation of the {@code long} argument as an unsigned integer in base 2.
toHexString string toHexString(long i): Returns a string representation of the {@code long} argument as an unsigned integer in base 16.
toOctalString string toOctalString(long i): Returns a string representation of the {@code long} argument as an unsigned integer in base 8.
toStr string toStr(long i, int radix): Returns a string representation of the first argument in the radix specified by the second argument.
toUnsignedString string toUnsignedString(long i, int radix): Returns a string representation of the first argument as an unsigned integer value in the radix specified by the second argument.
toUnsignedString0 string toUnsignedString0(long val, int shift): Format a long (treated as unsigned) into a string. @param val the value to format @param shift the log2 of the base to format in (4 for hex, 3 for octal, 1 for binary)
valueOf Long valueOf(long l): Returns a {@code Long} instance representing the specified {@code long} value. If a new {@code Long} instance is not required, this method should generally be used in preference to the constructor {@link #Long(long)}, as this method is likely to yield significantly better space and time performance by caching frequently requested values.
valueOf Long valueOf(string s, int radix): Returns a {@code Long} object holding the value extracted from the specified {@code String} when parsed with the radix given by the second argument. The first argument is interpreted as representing a signed {@code long} in the radix specified by the second argument, exactly as if the arguments were given to the {@link #parseLong(java.lang.String, int)} method. The result is a {@code Long} object that represents the {@code long} value specified by the string.
valueOf Long valueOf(string s): Returns a {@code Long} object holding the value of the specified {@code String}. The argument is interpreted as representing a signed decimal {@code long}, exactly as if the argument were given to the {@link #parseLong(java.lang.String)} method. The result is a {@code Long} object that represents the integer value specified by the string.

Static variables

MAX_VALUE long MAX_VALUE;: A constant holding the maximum value a {@code long} can have, 263-1.
MIN_VALUE long MIN_VALUE;: A constant holding the minimum value a {@code long} can have, -263.

Variables

SIZE enum int SIZE;: The number of bits used to represent a {@code long} value in two's complement binary form.
