Method Details

fetchSize

SearchLoadingOptionsStep fetchSize(int fetchSize)

Set the fetch size for this query, i.e. the amount of entities to load for each query to the database.

Higher numbers mean fewer queries, but larger result sets.

Parameters:

fetchSize - The fetch size. Must be positive or zero.

Returns:

this for method chaining.

SearchLoadingOptionsStep cacheLookupStrategy(EntityLoadingCacheLookupStrategy strategy)

Set the strategy for cache lookup before query results are loaded.

Parameters:

strategy - The strategy.

Returns:

this for method chaining.

 GraphSemantic semantic)

Customize fetching/loading of entity attributes and associations according to the given entity graph, with the given semantic.

Parameters:

graph - The graph to apply.

semantic - The semantic to use when applying the graph.
