clone

public ChunkCondition clone(IModel model,
                            VariableBindings bindings)
                     throws CannotMatchException

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,
                VariableBindings variableBindings,
                boolean isIterative)
         throws CannotMatchException

Description copied from interface: ICondition

Iteratively perform the resolution and binding for this condition. If this condition defines any variables, they are placed into the bindings map for other conditions to exploit. Similarly, it will resolve any bindings that it needs in order to be matched. If at any point the condition determines that it cannot be matched, the exception is to be thrown. Similarly, if isIterative is false, and there are unresolved bindings, the exception should be thrown.
Otherwise, the number of unresolved bindings is returned which allows the instantiation calculation determine if another resolution round is required.

Specified by:

bind in interface ICondition

Overrides:

bind in class ChunkTypeCondition

Returns:

number of unresolved variables

Throws:

CannotMatchException

hashCode

public int hashCode()

Overrides:

hashCode in class ChunkTypeCondition

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class ChunkTypeCondition
