Type Parameters:

E - Expression type

R - Resolved expression type

All Superinterfaces:

com.holonplatform.core.Expression.ExpressionResolverFunction<E,R>, com.holonplatform.core.ExpressionResolver<E,R>, Serializable

All Known Subinterfaces:

JdbcDatastoreExpressionResolver<E,R>, SQLExpressionResolver<E>

public interface SQLContextExpressionResolver<E extends com.holonplatform.core.Expression,R extends com.holonplatform.core.Expression>
extends com.holonplatform.core.ExpressionResolver<E,R>

An ExpressionResolver to be used with a SQLCompositionContext resultion context.

If the ResolutionContext is not a SQLCompositionContext an exception is thrown.
