Modifier and Type	Method and Description
boolean	applyMapEntry(PlanInterpretationNode node, java.util.Map<java.lang.Object,java.lang.Object> mapIn, java.util.Map<java.lang.Object,java.lang.Object> mapOut, PlanInterpretationNode key, PlanInterpretationNode value) invoked at a Map node in a YAML tree, after PlanInterpreter.applyMapBefore(PlanInterpretationNode, Map), and after recursing into the value and then key arguments supplied here, but before inserting it into the mapOut for this node.
void	applyYamlPrimitive(PlanInterpretationNode node) provides an opportunity for an interpreter to change the value at a node, using PlanInterpretationNode#get() and PlanInterpretationNode.setNewValue(Object)
static PlanInterpretationNode	currentNode() returns the current node, stored in a thread-local, to populate the dsl field of BrooklynDslDeferredSupplier instances
static void	currentNode(PlanInterpretationNode node) sets the current node

java.lang.Object	evaluate(java.lang.Object f, boolean deepEvaluation)
java.lang.Object	evaluateOn(java.lang.Object o, FunctionWithArgs f, boolean deepEvaluation)
boolean	isInterestedIn(PlanInterpretationNode node) guard to prevent any apply calls when an Interpreter is not interested in a node

public BrooklynDslInterpreter()

Method Detail

isInterestedIn

public boolean isInterestedIn(PlanInterpretationNode node)

Description copied from interface: PlanInterpreter

guard to prevent any apply calls when an Interpreter is not interested in a node

currentNode

public static PlanInterpretationNode currentNode()

returns the current node, stored in a thread-local, to populate the dsl field of BrooklynDslDeferredSupplier instances

currentNode

public static void currentNode(PlanInterpretationNode node)

sets the current node

currentNodeClear

public static void currentNodeClear()

applyYamlPrimitive

public void applyYamlPrimitive(PlanInterpretationNode node)

Description copied from interface: PlanInterpreter

provides an opportunity for an interpreter to change the value at a node, using PlanInterpretationNode#get() and PlanInterpretationNode.setNewValue(Object)

applyMapEntry

public boolean applyMapEntry(PlanInterpretationNode node,
                             java.util.Map<java.lang.Object,java.lang.Object> mapIn,
                             java.util.Map<java.lang.Object,java.lang.Object> mapOut,
                             PlanInterpretationNode key,
                             PlanInterpretationNode value)

Description copied from interface: PlanInterpreter

invoked at a Map node in a YAML tree, after PlanInterpreter.applyMapBefore(PlanInterpretationNode, Map), and after recursing into the value and then key arguments supplied here, but before inserting it into the mapOut for this node.

the return value indicates whether to add this key-value to the mapOut. if any interpreters return false, the entry is not added. (callers may modify mapOut to add/change values, or may modify key/value directly.)

Specified by:

applyMapEntry in interface PlanInterpreter

Overrides:
