Specified by:

setInput in interface Input<T>

Specified by:

shallowClone

public ToStream<T> shallowClone()

Description copied from interface: Operation

Operation implementations should ensure a ShallowClone method is implemented. Performs a shallow clone. Creates a new instance and copies the fields across. It does not clone the fields. If the operation contains nested operations, these must also be cloned.

Specified by:

shallowClone in interface Operation

Returns:

shallow clone

getOptions

public Map<String,String> getOptions()

Specified by:

getOptions in interface Operation

Returns:

the operation options. This may contain store specific options such as authorisation strings or and other properties required for the operation to be executed. Note these options will probably not be interpreted in the same way by every store implementation.

setOptions

public void setOptions(Map<String,String> options)

Specified by:

setOptions in interface Operation

Parameters:

options - the operation options. This may contain store specific options such as authorisation strings or and other properties required for the operation to be executed. Note these options will probably not be interpreted in the same way by every store implementation.
