oracle.spatial.spark.vector

Class SparkRecordInfo

java.lang.Object

oracle.spatial.spark.vector.SparkRecordInfo

All Implemented Interfaces:

java.io.Serializable

public class SparkRecordInfo
extends java.lang.Object
implements java.io.Serializable

Holds a subset of a single record's data, typically, the spatial information which is represented as an instance of oracle.spatial.geometry.JGeometry. Additional record information can be stored as SparkRecordInfo's fields using the add and get fields methods.

Constructor Detail

SparkRecordInfo

public SparkRecordInfo()

Creates an empty instance

SparkRecordInfo

public SparkRecordInfo(JGeometry geometry,
                       java.util.Map<java.lang.String,java.lang.Object> fields)

Creates a new instance containing the specified geometry and fields

Parameters:

geometry - a geometry

fields - a map containing fields to be held by the record info

SparkRecordInfo

public SparkRecordInfo(SparkRecordInfo recordInfo)

Creates a new instance with the same data than recordIndfo

Parameters:

recordInfo - another record info

Method Detail

addField

public void addField(java.lang.String name,
                     java.lang.Object val)

Adds a field to the record info

Parameters:

name -

val -

clear

public void clear()

Removes all the information from the record info. After calling this method, geometry will be null and there will not be fields.

clearFields

public void clearFields()

Removes all the fields from the record info

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

getField

public java.lang.Object getField(java.lang.String name)

Returns a field with the given name

Parameters:

name -

Returns:

a filed value or null if the field was not found

getFields

public java.util.Map<java.lang.String,java.lang.Object> getFields()

Gets a map containing the current fields if any

Returns:

getGeometry

public JGeometry getGeometry()

Gets the current geometry or null if there is not spatial information

Returns:

removeField

public void removeField(java.lang.String name)

Removes a field from the record info

Parameters:

name -

setFields

public void setFields(java.util.Map<java.lang.String,java.lang.Object> fields)

Sets the map entries as the current fields. This method is equivalent to call clearFields() followed by a call to addField(String, Object) for each entry in the map.

Parameters:

fields - a map containing the fields to be set

setGeometry

public void setGeometry(JGeometry geometry)

Sets the current geometry

Parameters:

geometry -

setRecordInfo

public void setRecordInfo(SparkRecordInfo recordInfo)

Copies the data (geometry and fields) from recordInfo

Parameters:

recordInfo -

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
