Package spoon.pattern.internal.node

Class ParameterNode

java.lang.Object
spoon.pattern.internal.node.AbstractNode
spoon.pattern.internal.node.ParameterNode
All Implemented Interfaces:
Matchers, PrimitiveMatcher, RepeatableMatcher, RootNode
public class ParameterNode extends AbstractNode
Represents pattern model variable Delivers/Matches 0, 1 or more values of defined parameter. The values may have type which extends CtElement or any other type of some SpoonModel attribute. E.g. String

    • replaceNode

      public boolean replaceNode​(RootNode oldNode, RootNode newNode)
      Description copied from interface: RootNode
      Call it to modify Pattern structure. It is actually called mainly by PatternBuilder. TODO: May be we can move this method into some internal interface?
      Parameters:
      oldNode - old RootNode
      newNode - new RootNode
      Returns:
      a true if `oldNode` was found in this RootNode or it's children and replaced by `newNode` false if `oldNode` was not found

    • generateTargets

      public <T> void generateTargets​(DefaultGenerator generator, ResultHolder<T> result, ImmutableMap parameters)
      Description copied from interface: RootNode
      Generates zero, one or more target depending on kind of this RootNode, expected `result` and input `parameters`
      Parameters:
      generator - Generator which drives generation process
      result - holder for the generated objects
      parameters - a ImmutableMap holding parameters

    • matchTarget

      public ImmutableMap matchTarget​(Object target, ImmutableMap parameters)
      Parameters:
      target - - to be matched element
      parameters - will receive the matching parameter values
      Returns:
      true if `element` matches with pattern of this matcher

    • getParameterInfo

      public ParameterInfo getParameterInfo()

    • isRepeatable

      public boolean isRepeatable()
      Returns:
      true if this matcher can be applied more then once in the same container of targets Note: even if false, it may be applied again to another container and to match EQUAL value

    • isMandatory

      public boolean isMandatory​(ImmutableMap parameters)
      Parameters:
      parameters - matching parameters
      Returns:
      true if this ValueResolver MUST match with next target in the state defined by current `parameters`. false if match is optional

    • isTryNextMatch

      public boolean isTryNextMatch​(ImmutableMap parameters)
      Parameters:
      parameters - matching parameters
      Returns:
      true if this ValueResolver should be processed again to match next target in the state defined by current `parameters`.

    • getMatchingStrategy

      public Quantifier getMatchingStrategy()
      Description copied from interface: RepeatableMatcher
      If two RepeatableMatchers in a list are matching the same element, then returned Quantifier defines how resolve this conflict
      Returns:
      Quantifier

    • forEachParameterInfo

      public void forEachParameterInfo​(BiConsumer<ParameterInfo,​RootNode> consumer)
      Description copied from interface: RootNode
      Calls consumer for each pair of parameter definition (ParameterInfo) and RootNode, which uses it
      Parameters:
      consumer - the receiver of pairs of ParameterInfo and RootNode

    • toString

      public String toString()
      Overrides:
      toString in class AbstractNode

    • matchAllWith

      public TobeMatched matchAllWith​(TobeMatched tobeMatched)
      Description copied from interface: Matchers
      Matches all matchers of this Matchers instance with `targets`
      Specified by:
      matchAllWith in interface Matchers
      Specified by:
      matchAllWith in interface RootNode
      Parameters:
      tobeMatched - to be matched target nodes and input parameters
      Returns:
