Class GreaterThanOrEqual<T>

java.lang.Object

net.kaczmarzyk.spring.data.jpa.domain.PathSpecification<T>

net.kaczmarzyk.spring.data.jpa.domain.ComparableSpecification<T>

net.kaczmarzyk.spring.data.jpa.domain.GreaterThanOrEqual<T>

All Implemented Interfaces:

org.springframework.data.jpa.domain.Specification<T>

public class GreaterThanOrEqual<T>
extends ComparableSpecification<T>

Filters with greater than or equal where-clause (e.g. where firstName >= "Homer").

Supports multiple field types: strings, numbers, booleans, enums, dates.

Field types must be Comparable (e.g, implement the Comparable interface); this is a JPA constraint.

NOTE: comparisons are dependent on the underlying database.

Comparisons of floats and doubles (especially floats) may be incorrect due to precision loss.

Comparisons of booleans may be dependent on the underlying database representation.

Comparisons of enums will be of their ordinal or string representations, depending on what you specified to JPA, e.g., @Enumerated(EnumType.STRING), @Enumerated(EnumType.ORDINAL) or the default (@Enumerated(EnumType.ORDINAL))
