aOperand - The operand to be applied to the value property.

Returns:

The BitwiseOperationBuilder as of the Builder-Pattern to chain multiple operations.

withXor

public BitwiseOperationBuilder withXor(Integer aOperand)

Applies a bitwise XOR operation to the value property with the given operand; the value is updated accordingly and the result can be retrieved with the ValueAccessor.getValue() method.

Specified by:

withXor in interface BitwiseOperationBuilder

Parameters:

aOperand - The operand to be applied to the value property.

Returns:

Specified by:

withNot in interface BitwiseOperationBuilder

Returns:

The BitwiseOperationBuilder as of the Builder-Pattern to chain multiple operations.

isMaskable

public boolean isMaskable(Integer aMask)

Tests if the bits set in the mask argument are also set in the value property ("the value property is maskable with the given mask"). If this is the case true is returned. Else false is returned. Additionally bits set in the value property are not considered in the result. The bit-length of the mask may not be the same as the bit-length of the value.

Specified by:

isMaskable in interface BitwiseOperationBuilder

Parameters:

aMask - The mask which's true bits are to be verified against the value property.

Returns:

True in case the value property is maskable by the given mask.

isTrueAt

public boolean isTrueAt(int aPosition)

Checks if is true at.

Specified by:

isTrueAt in interface BitwiseOperationBuilder

Parameters:

aPosition - the position

Returns:

true, if is true at

toBitwiseAND

protected static int toBitwiseAND(int aValueA,
                                  int aValueB)

The result of this method is a contransceiver of the parameters valueA and valueB. The operation is a bitwise logical AND.

Parameters:

aValueA - Value A to be used.

aValueB - Value B to be used.

Returns:

The boolean result of the bitwise AND.

toBitwiseNOT

protected static int toBitwiseNOT(int aValue)

The result of this method is the negation of the given value. The operation is a bitwise logical NOT.

Parameters:

aValue - Value to be used.

Returns:

The boolean result of the bitwise NOT.

toBitwiseOR

protected static int toBitwiseOR(int aValueA,
                                 int aValueB)

The result of this method is a distransceiver of the parameters valueA and valueB. The operation is a bitwise logical OR.

Parameters:

aValueA - Value A to be used.

aValueB - Value B to be used.

Returns:

The boolean result of the bitwise OR.

toBitwiseXOR

protected static int toBitwiseXOR(int aValueA,
                                  int aValueB)

The result of this method is an exclusive distransceiver of the parameters valueA and valueB. The operation is a bitwise logical XOR.

Parameters:

aValueA - Value A to be used.

aValueB - Value B to be used.

Returns:

The boolean result of the bitwise XOR.

isBitwiseMaskable

protected static boolean isBitwiseMaskable(int aValue,
                                           int aMask)

Tests if the bits set in the parameter mask are also set in the parameter value. If this is the case true is returned. Else false is returned. Additionally bits set in the parameter value are not considered in the result. The bit-length of the mask may not be the same as the bit-length of the value. CATION: This method may not be very optimized!

Parameters:

aValue - The value to see if the true values in the mask are also true in the value.

aMask - The mask which's true values are to be verified against the provided value.

Returns:

Description is currently not available!

isTrueAt

protected static boolean isTrueAt(int aValue,
                                  int aPos)

Tests whether the bit at the given position is set in the parameter value and returns true if this is the case. Else false is returned. Also Returns false if an index out of range is provided. CATION: This method may not be very optimized!

Parameters:

aValue - The value interpreted as a bit-field.

aPos - The position of the bit-field to be tested.

Returns:

True in case the bit in the bit-field at the given position is true.
