Constructor Detail

EsType

protected EsType(CloudNode node,
      String classId,
      Double relevance)

Direct use of this constructor is discouraged. Use the CloudNode.addEsType method instead.

Parameters:

node - the owner cluster of this type.

classId - the identifier of the corresponding KC database type(an EsType is actually an association between a Type and a CloudNode).

relevance - the relevance value associated with this type.

See Also:

CloudNode.addEsType(String, Double), Type

Method Detail

getClassId

public String getClassId()

Get current type identifier (an EsType is actually an association between a Type and a CloudNode).

Returns:

the id of the associated Type

Type

setClassId

protected void setClassId(String classId)

Set current term identifier. To be set using the constructor (direct use is discouraged).

getRelevance

public Double getRelevance()

Get current type relevance.

Returns:

current type relevance value.

setRelevance

public void setRelevance(Double relevance)

Set current type relevance.

Parameters:

relevance - current type relevance value.

getId

public Integer getId()

Get current essential-type identifier (database purposes only)

Returns:

current esType identifier.

getNode

public CloudNode getNode()

Get the owner CloudNode.

Returns:

the owner CloudNode.

setNode

protected void setNode(CloudNode node)

Set the identifier of the owner node.

equals

public boolean equals(Object obj)

Evaluates the equality between the current object and the one passed as argument.

Overrides:

equals in class Object

Returns:

• true if the given object is instance of EsType class and this classId is equal to the given object's classId.
• false otherwise

hashCode

public int hashCode()

Returns the hashCode of the contained classId.

Overrides:

hashCode in class Object

Returns:

a call to the hashCode method of the String classId.

compareTo

public int compareTo(EsType o)

Implementation of a comparison value between two EsType objects considering the relevance of the types.

Specified by:

compareTo in interface Comparable<EsType>

Returns:

the difference between the two EsType relevances or, if this difference is 0, the comparison between the two classId.

toString

public String toString()

Returns a string representation of the current essential type.

Overrides:

toString in class Object

Returns:

A string containing the class identifier and its relevance for the referred cloud node.
