Interface LeftOperandHandler

All Known Implementing Classes:

AbstractDocumentLeftOperandHandler, BusinessDataLeftOperandHandler, DataLeftOperandHandler, DocumentLeftOperandHandler, DocumentListLeftOperandHandler, ExternalDataLeftOperandHandler, TransientDataLeftOperandHandler

public interface LeftOperandHandler

Tells the engine how to retrieve and update a left operand having the specified type e.g. a data left operand handler will get data from database and set the data back in database

Method Detail

getType

java.lang.String getType()

update

java.lang.Object update(SLeftOperand sLeftOperand,
                        java.util.Map<java.lang.String,java.lang.Object> inputValues,
                        java.lang.Object newValue,
                        long containerId,
                        java.lang.String containerType)
                 throws SOperationExecutionException

Parameters:

inputValues - contains value(s) given by the strategy to update the left operand with

sLeftOperand - the left operand

newValue - the value to set the element with

containerId - the container id

containerType - the container type

Throws:

SOperationExecutionException

delete

void delete(SLeftOperand sLeftOperand,
            long containerId,
            java.lang.String containerType)
     throws SOperationExecutionException

Throws:

SOperationExecutionException

loadLeftOperandInContext

void loadLeftOperandInContext(SLeftOperand sLeftOperand,
                              long leftOperandContainerId,
                              java.lang.String leftOperandContainerType,
                              SExpressionContext contextToSet)
                       throws SBonitaReadException

retrieve the left operand and put it in context as needed by the left operand

Parameters:

sLeftOperand - the left operand

leftOperandContainerId - the left operand container id. Used to execute the left Operand in the correct context

leftOperandContainerType - the left operand container type. Used to execute the left Operand in the correct context

contextToSet - the context to add the value i

Throws:

SBonitaReadException

loadLeftOperandInContext

                              long leftOperandContainerId,
                              java.lang.String leftOperandContainerType,
                              SExpressionContext contextToSet)
                       throws SBonitaReadException
