Method Detail

setReadOnly

public void setReadOnly(boolean state)

Determine whether this value should be readable only, by the interview user. The default state is false.

Parameters:

state - True if readonly, false otherwise.

setVisible

public void setVisible(boolean state)

Make value outwardly visible or invisible. This does not mean it is not accessible, just that it is not shown when possible in the user interfaces. The default state is true.

Parameters:

state - True if the property at constrained by this object should be visible.

isReadOnly

public boolean isReadOnly()

Determine if this value is a read-only value. The default is false.

Returns:

True if read-only, false otherwise.

isVisible

public boolean isVisible()

Is this property (and value) visible? True by default.

Returns:

True if it should be visible, false otherwise.

setUnsetAllowed

public void setUnsetAllowed(boolean state)

May the answer be set to an unanswered state. If false, the question will always be answered. If true, the question may be set to an affirmative, negative or unset response. An unset response is considered an incomplete answer by default.

Parameters:

state - True if the user is allowed to make this value unset.

isUnsetAllowed

public boolean isUnsetAllowed()

Is an unset response allowed. The default is true, unless indicated otherwise by a subclass.

Returns:

True if the unsetting the answer is allowed.

See Also:

setUnsetAllowed(boolean)

isValid

public java.lang.String isValid(java.lang.String v)

Is the given value valid for this field? Since this constraint class has no particular typing, the default only check that the value is non-empty. You may override this method to do custom checking, or you may do your checking in getInvalidKeys() which by default defers to the associated constraint object (if any).

Parameters:

v - The value to check.

Returns:

Null if the valid is valid, a localized reason string otherwise.
