Class QuerydslHttpRequestContext

java.lang.Object

org.bitbucket.gt_tech.spring.data.querydsl.value.operators.experimental.QuerydslHttpRequestContext

public final class QuerydslHttpRequestContext
extends Object

Context is core to experimental features using QuerydslHttpRequestContextAwareServletFilter as it decorates the default HttpServletRequest by extracting all the value operators and maintaining them locally against their respective Path in this context. This allows Spring Web QuerydslPredicateArgumentResolver to continue with its strong type-conversion hiding the fact that there were value operators. Value operators enabled actual value is provided to ExpressionProvider during later phases for their usage in actual Expression for querying.
