CstLiteralBits

public abstract class CstLiteralBits extends TypedConstant
Constants which are literal bitwise values of some sort.

Fields Summary
Constructors Summary
Methods Summary
public booleanfitsIn16Bits()
Returns true if this value can fit in 16 bits with sign-extension.

return
true if the sign-extended lower 16 bits are the same as the value.

        if (! fitsInInt()) {
            return false;
        }
        
        int bits = getIntBits();
        return (short) bits == bits;
    
public booleanfitsIn8Bits()
Returns true if this value can fit in 8 bits with sign-extension.

return
true if the sign-extended lower 8 bits are the same as the value.

        if (! fitsInInt()) {
            return false;
        }

        int bits = getIntBits();
        return (byte) bits == bits;
    
public abstract booleanfitsInInt()
Returns whether or not this instance's value may be accurately represented as an int. The rule is that if there is an int which may be sign-extended to yield this instance's value, then this method returns true. Otherwise, it returns false.

return
true iff this instance fits in an int

public abstract intgetIntBits()
Gets the value as int bits. If this instance contains more bits than fit in an int, then this returns only the low-order bits.

return
the bits

public abstract longgetLongBits()
Gets the value as long bits. If this instance contains fewer bits than fit in a long, then the result of this method is the sign extension of the value.

return
the bits
