Object	getValue() Returns the value or null in case the value is null.
String	getValueSerialized() Returns the serialized value.
boolean	isDeserialized() Returns true in case the value is deserialized.

Method Detail

isDeserialized

boolean isDeserialized()

Returns true in case the value is deserialized. If this method returns true, it is safe to call the getValue() method

Returns:

true if the object is deserialized.

getValue

Object getValue()

Returns the value or null in case the value is null.

Specified by:

getValue in interface TypedValue

Returns:

the value represented by this TypedValue.

Throws:

IllegalStateException - in case the value is not deserialized. See isDeserialized().

getValueSerialized

String getValueSerialized()

Returns the serialized value. In case the serializaton data format (as returned by getSerializationDataFormat()) is not text based, a base 64 encoded representation of the value is returned The serialized value is a snapshot of the state of the value as it is serialized to the process engine database.

getSerializationDataFormat

String getSerializationDataFormat()

The serialization format used to serialize this value.

Returns:

the serialization format used to serialize this variable.

getType

SerializableValueType getType()

Description copied from interface: TypedValue
