Method Detail

canCreateValue

public boolean canCreateValue(java.lang.Object obj)

Test to see if a BooleanValue can be created from the specified object.

Specified by:

canCreateValue in interface ValueStrategy

Parameters:

obj - Any object.

Returns:

true if create will succeed, false otherwise.

compare

public long compare(ValueComponent obj1,
                    ValueComponent obj2)

Tests to see how two BooleanValues compare.

Specified by:

compare in interface Strategy

Parameters:

obj1 - Must be a BooleanValue.

obj2 - Must be a BooleanValue.

Returns:

0 if equal, -1 if obj1=false and obj2=true +1 if obj1=true and obj2=false other non-zero number if the syntaxes are different.

ValueComponent.compareTo(ValueComponent)

createValueComponent

public ValueComponent createValueComponent()

Factory a new ValueComponent using default values.

Specified by:

createValueComponent in interface Strategy

Returns:

The new BooleanValue initialized to true.

createValueComponent

public ValueComponent createValueComponent(java.lang.Object obj)
                                    throws ComponentCreationException

Factory a new ValueComponent using specified values.

Specified by:

createValueComponent in interface Strategy

Parameters:

obj - The object used as the initial value.

Returns:

The new BooleanValue initialized to true.

Throws:

ComponentCreationException - if 'obj' cannot be used as the initial value.

equals

public boolean equals(ValueComponent obj1,
                      ValueComponent obj2)

Tests to see if two BooleanValues are identical.

Specified by:

equals in interface Strategy

Parameters:

obj1 - Must be a BooleanValue.

obj2 - Any other Value type.

Returns:

true if 'obj1' is equal to 'obj2'.

ValueComponent.equals(Object)

isWithinBounds

public boolean isWithinBounds(ValueComponent comp,
                              long lowerBound,
                              long upperBound)

Check to see if a BooleanComponent is within certain bounds.

Specified by:

isWithinBounds in interface Strategy

Parameters:

comp - The ValueComponent holding the values.

lowerBound - The lower bound.

upperBound - The upper bound.

Returns:

Always false.

toString

public java.lang.String toString(ValueComponent obj)

Converts the ValueComponent to a string.

Specified by:

toString in interface Strategy

Parameters:

obj - Must be a BooleanValue.

Returns:

String representation of the value.
