Method Detail

getPrefix

public Word<I> getPrefix()

Description copied from class: Query

Returns the prefix part of this query. The prefix of a query is responsible for transferring the system into a certain state, but (apart from that) does not directly influence the output.

Specified by:

getPrefix in class Query<I,D>

Returns:

the prefix of this query

getSuffix

public Word<I> getSuffix()

Description copied from class: Query

Returns the suffix part of this query. The suffix of a query is the experiment performed on the system when in the state it was transferred into by the prefix, and thus directly influences the output.

Specified by:

getSuffix in class Query<I,D>

Returns:

the suffix of this query

toStringWithAnswer

public String toStringWithAnswer(D answer)

Returns the string representation of this query, including a possible answer. This method should be used by classes extending AbstractQuery for their toString method to ensure output consistency.

Returns:

A string of the form "Query[<prefix>|<suffix> / <answer>]". If the query has not been answered yet, <answer> will be null.
