Example 1 with XLSSchemaReader

use of eu.esdihumboldt.hale.io.xls.reader.XLSSchemaReader in project hale by halestudio.

the class XLSInstanceIOTest method test.

/**
 * Exports the instances created by
 * {@link XLSInstanceWriterTestExamples#createInstanceCollection} into a
 * temporary XLS file by executing {@link XLSInstanceWriter#execute}.
 * Afterwards, the schema is read by {@link XLSSchemaReader} and the
 * instances are loaded by {@link XLSInstanceReader}. Each of the imported
 * instances are compared with the original instances. In addtion, a
 * different set of instances is compared with the imported instances.
