Method Detail

put

void put(String source,
       int index,
       Object value)

Adds a parameter value at its position in the expected method.

Parameters:

source - the source used to get the value. Used for debugging information.

index - the position in the method

value - the parameter value

put

void put(String sourceMethod,
       int aggregateIndex,
       int index,
       Object value)

Adds a parameter value for the specified aggregate root at its position in the expected method.

Parameters:

sourceMethod - the source method used to get the value. Used for debugging information.

aggregateIndex - the index corresponding to the aggregate root position in the tuple of aggregate roots.

index - the position in the method

value - the parameter value

parameters

Object[] parameters()

Gives the ordered list of parameters.

Returns:

array of parameters

parametersOfAggregateRoot

Object[] parametersOfAggregateRoot(int aggregateIndex)

Gives the ordered list of parameters for specified index.

Parameters:

aggregateIndex - the index corresponding to the aggregate root position in the tuple of aggregate roots.

Returns:

the array of parameters

uniqueElement

Object uniqueElement()

Gives the first parameter of the first aggregate.

Returns:

array of parameters

uniqueElementForAggregateRoot

Object uniqueElementForAggregateRoot(int aggregateIndex)

Gives the first parameter of the specified aggregate.

Parameters:

aggregateIndex - the index corresponding to the aggregate root position in the tuple of aggregate roots.

Returns:

array of parameters

isEmpty

boolean isEmpty()

Indicates whether the holder contains parameters. If there

This is equivalent to isEmptyForAggregateRoot(-1) || isEmptyForAggregateRoot(0). If there is only one aggregate root, the index is -1, otherwise it starts at 0.

Returns:

true if the holder doesn't contain parameters, false otherwise

isEmptyForAggregateRoot

boolean isEmptyForAggregateRoot(int aggregateIndex)

Indicates whether the holder contains parameters for the aggregate root at the aggregateIndex position in the tuple.

It starts at the index 0, or -1 if there is only one aggregate defined.

It checks if there is at least one aggregate defined and if the first aggregate as at least one parameter.

Parameters:

aggregateIndex - the index corresponding to the aggregate root position in the tuple of aggregate roots.

Returns:

true if the holder doesn't contain parameters, false otherwise
