Interface QueryDefinition

public interface QueryDefinition

In general, a query definition specifies a Boolean function of multiple binary-valued conditions. This Boolean function of multiple conditions combines these conditions using AND, OR, and NOT operators. Each of these conditions has three parts:

• 1. Metadata Element name or identification, to be compared
• 2. Comparison value, to be compared to the value of the Metadata Element
• 3. Type of comparison to perform, between the comparison value and the value of the Metadata Element
