clone

public ChunkCondition clone(IModel model,

Description copied from interface: ICondition

attempt to clone this condition before it will be bound in the instantiation phase. We pass the current bindings so that the condition can do an early rejection if possible.

Specified by:

clone in interface ICondition

Overrides:

clone in class ChunkTypeCondition

Returns:

a writable copy of the condition that will be bound

Throws:

CannotMatchException - if there is no way this condition can be matched

bind

public int bind(IModel model,
                java.util.Map<java.lang.String,java.lang.Object> variableBindings,
                boolean isIterative)
         throws CannotMatchException

bind and create a new ChunkCondition with the variables fully resolved

Specified by:

bind in interface ICondition

Overrides:

bind in class ChunkTypeCondition

Returns:

number of unresolved variables

Throws:

CannotMatchException
