Method Detail

getSupportedClasses

protected Class[] getSupportedClasses()

Creates a list of classes supported by the validator.

Returns:

getDisplayList

public String[] getDisplayList()

Returns the value of DisplayList.

Returns:

the value of DisplayList

See Also:

setDisplayList(java.lang.String[])

getStringList

public String[] getStringList()

Returns the value of DisplayList. If the user has not set a Displaylist, the validator will construct one from the picklist using the format() method on the items in the picklist. If the picklist has not been set, then this method will return null.

Returns:

See Also:

setDisplayList(java.lang.String[]), AbstractValidator.setPickList(javax.swing.ListModel)

setDisplayList

public void setDisplayList(String[] list)

Sets the display list, which specifies a String format for the value in the picklist independent of what the format() method generates. This is particularly useful in the case of Enumerated Database types where 1 = Mr, 2 = Mrs, etc. In this case, you would set the DisplayList so that if the internal value was 1, then Mr would be displayed.

Parameters:

list -

setMax

public void setMax(long max)

Sets the maximum valid value.

Parameters:

max -

setMin

public void setMin(long min)

Sets the minimum valid value.

Parameters:

min -
