Constructor Detail

UnaryBitFunctionNode

public UnaryBitFunctionNode()

Constructs an empty result node. NOTE: This instance is broken until non-optional member data is set.

UnaryBitFunctionNode

public UnaryBitFunctionNode(ExpressionNode arg,
                            int numBits)

Constructs an instance of this class with given argument and number of bits.

Parameters:

arg - The argument for this function.

numBits - The number of bits to operate on.

Method Detail

getNumBits

public final int getNumBits()

Returns the number of bits to operate on.

Returns:

The number of bits.

setNumBits

public UnaryBitFunctionNode setNumBits(int numBits)

Sets the number of bits to operate on.

Parameters:

numBits - The number of bits.

Returns:

This, to allow chaining.
