NodeSpecificHasherBase

public NodeSpecificHasherBase(DuplocatorSettings settings,
                              FragmentsCollector callback,
                              DuplicatesProfileBase duplicatesProfile)

NodeSpecificHasherBase

public NodeSpecificHasherBase(DuplocatorSettings settings,
                              FragmentsCollector callback,
                              DuplicatesProfileBase duplicatesProfile,
                              boolean forIndexing)

Method Detail

getNodeFilter

public NodeFilter getNodeFilter()

getNodeHash

public int getNodeHash(PsiElement node)

Description copied from class: NodeSpecificHasher

getNodeHash is called on each node, which was returned by getNodeChildren method

Specified by:

getNodeHash in class NodeSpecificHasher

getNodeCost

public int getNodeCost(PsiElement node)

Description copied from class: NodeSpecificHasher

Used in TreeComparator and TreeHashers

Specified by:

getNodeCost in class NodeSpecificHasher

Returns:

-1 if you want to ignore this node. Note: only nodes with equal values can be considered as equal (areNodesEqual will be called further) This cost will be used when calculating compound nodes. See DuplocatorSettings#LOWER_BOUND

getNodeChildren

public java.util.List<PsiElement> getNodeChildren(PsiElement node)

Description copied from class: NodeSpecificHasher

List all of the nodes to process within TreeComparator

Specified by:

getNodeChildren in class NodeSpecificHasher

areNodesEqual

public boolean areNodesEqual(PsiElement node1,
                             PsiElement node2)

Description copied from class: NodeSpecificHasher

This is dual function to getNodeCost, checks whether 2 nodes with same costs are really equal

Specified by:

areNodesEqual in class NodeSpecificHasher

areTreesEqual

public boolean areTreesEqual(PsiElement root1,
                             PsiElement root2,
                             int discardCost)

Overrides:

areTreesEqual in class NodeSpecificHasher

getDuplicatesProfile

public DuplicatesProfileBase getDuplicatesProfile()

checkDeep

public boolean checkDeep(PsiElement node1,
                         PsiElement node2)

Specified by:

checkDeep in class NodeSpecificHasher

visitNode

public void visitNode(PsiElement node)

hashingFinished

public void hashingFinished()

Description copied from interface: DuplocateVisitor

Is not invoked when index is used
