Method Details

getGraph

public PgxGraph getGraph()

Gets the graph.

Returns:

the graph the entity is bound to

serialize

public Object serialize()

Method to get the entity as an object that can be serialized for algorithms.

getId

public ID getId()

Gets the id.

Returns:

the entity's id

getType

public IdType getType()

Gets the type.

Returns:

the entity's type

getPropertyAsync

public <V> PgxFuture<V> getPropertyAsync(String propertyName)

Gets the value of a property.

NOTE: If you want to iterate over all values of a property, use Property.getValuesAsync() instead.

Parameters:

propertyName - the property name

Returns:

the value

setPropertyAsync

public <V> PgxFuture<Void> setPropertyAsync(String propertyName,
 V value)

Sets the value of a property.

NOTE: If you want to set several values of a property, use Property.setValuesAsync(Map) instead.

Parameters:

propertyName - the property name

value - the value of the property

Returns:

A future which completes once the value was set. The returned future will completely exceptionally if the given property does not exist.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

getProperty

public <V> V getProperty(String propertyName)
                  throws ExecutionException,
InterruptedException

Blocking version of getPropertyAsync(String). Calls getPropertyAsync(String) and waits for the returned PgxFuture to complete.

Throws:

InterruptedException - if the caller thread gets interrupted while waiting for completion.

ExecutionException - if any exception occurred during asynchronous execution. The actual exception will be nested.

setProperty

public <V> void setProperty(String propertyName,
 V value)
                     throws ExecutionException,
InterruptedException

Blocking version of setPropertyAsync(String, Object). Calls setPropertyAsync(String, Object) and waits for the returned PgxFuture to complete.

Throws:

InterruptedException - if the caller thread gets interrupted while waiting for completion.

ExecutionException - if any exception occurred during asynchronous execution. The actual exception will be nested.
