Method Detail

assignFrom

public void assignFrom(Object obj)

Description copied from interface: AssignableValue

Assigns value from an Object.

Specified by:

assignFrom in interface AssignableValue

Overrides:

assignFrom in class NullablePrimitive

Parameters:

obj - value to assign, or null to set null

setNumber

protected void setNumber(Number number)

Description copied from class: NullablePrimitive

Assignment from abstract Number object.

Specified by:

setNumber in class NullablePrimitive

Parameters:

number - a new non-null value to be assigned

setLong

protected void setLong(long n)

Description copied from class: NullablePrimitive

Assignment from non-null long value.

Specified by:

setLong in class NullablePrimitive

Parameters:

n - long value to assign

setBit

public void setBit(boolean bit)

Description copied from interface: BitReference

Sets the bit value referenced by this.

Specified by:

setBit in interface BitReference

Parameters:

bit - new value

getBit

public boolean getBit()

Specified by:

getBit in interface BitReference

Returns:

the bit value referenced by this

convertString

public static boolean convertString(String s)

Implements cast from string to non-nullable boolean Invoked by generated code

assignFromAnd3VL

public void assignFromAnd3VL(boolean n0,
                             boolean v0,
                             boolean n1,
                             boolean v1)

Implements the three-valued-logic version of the AND operator. Invoked by generated code.

Parameters:

n0 - null indictator for arg0

v0 - truth value of arg0 when !n0

n1 - null indicator for arg1

v1 - truth value of arg1 when !n1

assignFromOr3VL

public void assignFromOr3VL(boolean n0,
                            boolean v0,
                            boolean n1,
                            boolean v1)

Implements the three-valued-logic version of the OR operator. Invoked by generated code.

Parameters:

n0 - null indictator for arg0

v0 - truth value of arg0 when !n0

n1 - null indicator for arg1

v1 - truth value of arg1 when !n1
