Class CellValidator

java.lang.Object

com.stratio.deep.entity.CellValidator

All Implemented Interfaces:

Serializable

public class CellValidator
extends Object
implements Serializable

Defines a serializable CellValidator.

This object wraps the complexity of obtaining the Cassandra's AbstractType associated to a Cell.

In the case of collection types, a simple cassandra marshaller qualified name is not enough to fully generate an AbstractType, we also need the type(s) the collection holds.

Method Detail

cellValidator

public static CellValidator cellValidator(Field field)

Factory method that builds a CellValidator from an IDeepType field.

Parameters:

field - the IDeepType field.

Returns:

a new CellValidator associated to the provided object.

cellValidator

public static CellValidator cellValidator(com.datastax.driver.core.DataType type)

Factory method that builds a CellValidator from a DataType object.

Parameters:

type - the data type coming from the driver.

Returns:

a new CellValidator associated to the provided object.

cellValidator

public static <T> CellValidator cellValidator(T obj)

Generates a CellValidator for a generic instance of an object. We need the actual instance in order to differentiate between an UUID and a TimeUUID.

Type Parameters:

T - the generic type of the provided object instance.

Parameters:

obj - an instance to use to build the new CellValidator.

Returns:

a new CellValidator associated to the provided object.

getAbstractType

public org.apache.cassandra.db.marshal.AbstractType<?> getAbstractType()

Generates the cassandra marshaller (AbstractType) for this CellValidator.

Returns:

an instance of the cassandra marshaller for this CellValidator.

getValidatorClassName

public String getValidatorClassName()

Getter for validatorClassName.

Returns:

the cassandra marshaller class name.

getValidatorTypes

public Collection<String> getValidatorTypes()

Getter for validatorTypes.

Returns:

a collection of validator type names.

validatorKind

public CellValidator.Kind validatorKind()

Getter for validatorKind.

Returns:

the Kind associated to this CellValidator.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

getCqlTypeName

public com.datastax.driver.core.DataType.Name getCqlTypeName()

Returns:

the original CQL3 type name (if known, null otherwise)
