Example 6 with QuerySpace

use of org.hibernate.loader.plan.spi.QuerySpace in project hibernate-orm by hibernate.

the class QuerySpacesImpl method registerQuerySpace.

/**
	 * Feeds a QuerySpace into this spaces group.
	 *
	 * @param querySpace The space
	 */

Example 7 with QuerySpace

use of org.hibernate.loader.plan.spi.QuerySpace in project hibernate-orm by hibernate.

the class QuerySpaceTreePrinter method write.

/**
	 * Returns a String containing the {@link QuerySpaces} graph as a tree structure, starting
	 * at a particular depth.
	 *
	 * The value for depth indicates the number of indentations that will
	 * prefix all lines in the returned String. Root query spaces will be written with depth + 1
	 * and the depth will be further incremented as joined query spaces are traversed.
	 *
	 * An indentation is defined as the number of characters defined by {@link TreePrinterHelper#INDENTATION}.
	 *
	 * @param spaces The {@link QuerySpaces} object.
	 * @param depth The intial number of indentations
	 * @param aliasResolutionContext The context for resolving table and column aliases
	 *        for the {@link QuerySpace} references in <code>spaces</code>; if null,
	 *        table and column aliases are not included in returned value.
	 * @param printWriter The print writer for writing.
