Method Detail

value

public T value()

Gets indexed value. This method may return null only if actual value is null. Otherwise, it will unmarshal the GridIndexingEntity.bytes() and return the actual value.

Specified by:

value in interface GridIndexingEntity<T>

Returns:

Indexed value.

bytes

public byte[] bytes()

Optional bytes for marshaled indexed value. Certain SPI implementations may keep objects in unmarshalled form and therefore will not provide marshaled bytes for them.

Specified by:

bytes in interface GridIndexingEntity<T>

Returns:

Optional marshaled value.

hasValue

public boolean hasValue()

Flag indicating whether this entity contains unmarshalled value.

Specified by:

hasValue in interface GridIndexingEntity<T>

Returns:

True if entity contains unmarshalled value, false otherwise.

toString

public String toString()

Overrides:
