Method Detail

writable

public boolean writable()

Description copied from interface: MutableObject

Returns true if this mutable object is still writable. That is, the #toImmutable() method (defined on a sub-interface) has not yet been invoked.

Specified by:

writable in interface MutableObject

Returns:

true if this mutable object is still writable

toString

public String toString()

Overrides:

toString in class Instruction

addAction

public InstrMutableAction addAction(Action action)

Adds the specified action to this instruction.

Parameters:

action - the action to add

Returns:

self, for chaining

Throws:

InvalidMutableException - if this instance is no longer writable

NullPointerException - if action is null

validateActions

protected abstract void validateActions()

Subclasses should validate the actions, and silently return if all is well. If a problem is detected, a ValidationException should be thrown.

Throws:

ValidationException - if a problem with the actions

toDebugString

public String toDebugString(int indent)

Description copied from class: Instruction

Returns a string representation useful for debugging. This default implementation delegates to Instruction.toString(), but subclasses are free to override this behavior.

Overrides:

toDebugString in class Instruction

Parameters:

indent - the number of spaces with which to prefix each line

Returns:

a (possibly multi-line) string representation of this instruction
