 com.broadleafcommerce.data.tracking.core.TrackableRepository<D> repository)

Method Details

readPageWithEqualPredicate

@SafeVarargs
public final org.springframework.data.domain.Page<D> readPageWithEqualPredicate(@Nullable
 com.broadleafcommerce.data.tracking.core.context.ContextInfo contextInfo,
 @Nullable
 org.springframework.data.domain.Pageable page,
 String paramName,
 String paramValue,
 Function<jakarta.persistence.criteria.Root<D>,jakarta.persistence.criteria.Expression<String>> fieldExpressionFunction,
 Function<jakarta.persistence.criteria.Root<D>,jakarta.persistence.criteria.Predicate>... additionalPredicateFunctions)

Reads a page of trackables based on some "equals" condition.

For example, someone wanting to find a page of trackables where "someId" is "123" would invoke this with something similar to: readPageWithEqualPredicate( contextInfo, page, "someId", "123", root -> root.get("someId"));

Parameters:

contextInfo - the context information of the request

page - the requested page to load

paramName - the name of the parameter being tested in the "equals" condition

paramValue - the value the parameter should have for the "equals" condition

fieldExpressionFunction - a function that generates an expression for the field to test in the "equals" condition

additionalPredicateFunctions - any additional predicates to add to the query

Returns:

a page of trackables

getManagedType

public Class<D> getManagedType()
