Method Detail

addNeighbor

public void addNeighbor(DependencyRelation relation)

Adds a relation from node to another node.

Parameters:

relation - a relation connecting this node to another

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Returns a hash that is the XOR of the part of speech hash and the word hash.

Overrides:

hashCode in class Object

neighbors

public List<DependencyRelation> neighbors()

Returns the list of neighbors to the current node. Note that this list include both relations where the current node is the head node and relations where the current node is the dependent.

Specified by:

neighbors in interface DependencyTreeNode

pos

public String pos()

Returns the part of speech tag for this node.

Specified by:

pos in interface DependencyTreeNode

toString

public String toString()

Returns "word:pos".

Overrides:

toString in class Object

word

public String word()

Returns the word stored in this node.

Specified by:

word in interface DependencyTreeNode

lemma

public String lemma()

The lemmatized version of the word, if there is any.

Specified by:

lemma in interface DependencyTreeNode

index

public int index()

Returns the index used by this DependencyTreeNode in an array.

Specified by:

index in interface DependencyTreeNode
