Method Detail

equal

@Deprecated
public static boolean equal(@Nullable Object o0,
                                        @Nullable Object o1)

Deprecated. Use Objects.equals(java.lang.Object, java.lang.Object).

hash

public static int hash(@Nullable Object v)

hashCode

@Deprecated
public static int hashCode(double v)

Deprecated. Use Double.hashCode(double)

Computes the hash code of a double value. Equivalent to Double.hashCode(double), but that method was only introduced in JDK 1.8.

Parameters:

v - Value

Returns:

Hash code

hashCode

@Deprecated
public static int hashCode(float v)

Deprecated. Use Float.hashCode(float)

Computes the hash code of a float value. Equivalent to Float.hashCode(float), but that method was only introduced in JDK 1.8.

Parameters:

v - Value

Returns:

Hash code

hashCode

@Deprecated
public static int hashCode(long v)

Deprecated. Use Long.hashCode(long)

Computes the hash code of a long value. Equivalent to Long.hashCode(long), but that method was only introduced in JDK 1.8.

Parameters:

v - Value

Returns:

Hash code

hashCode

@Deprecated
public static int hashCode(boolean v)

Deprecated. Use Boolean.hashCode(boolean)

Computes the hash code of a boolean value. Equivalent to Boolean.hashCode(boolean), but that method was only introduced in JDK 1.8.
