Field Detail

scm_version

public static final Version scm_version

Constant instance of version information for class.

Method Detail

areAllBitsSet

public static final boolean areAllBitsSet(int value,
                                          int flags)

Returns true iff all bits stipulated in flags are set in value.

Parameters:

value - The value against which to test the flags

flags - The flag(s) with which to test the value

areAnyBitsSet

public static final boolean areAnyBitsSet(int value,
                                          int flags)

Returns true if any bits stipulated in flags are set in value.

Parameters:

value - The value against which to test the flags

flags - The flag(s) with which to test the value

modifyBits

public static final int modifyBits(int value,
                                   int remove,

Parameters:

value - The value to modify

remove - The bit values to remove from value

add - The bit values to add to value

removeBits
