ByEntityFilterOperation

ByEntityFilterOperation

class ByEntityFilterOperation(val attrId: Int, val filterBuilder: FilterBuilder)
A class representing a filter operation for Entity attributes. It is used to build a filter expression by specifying equality operations on Entity attribute values.
This class provides a method for creating filter nodes that represent equality conditions on Entity attributes. These filter nodes can then be combined using logical operators (AND, OR) to create complex filtering conditions.
Example:
// Find entities where entityVar equals a specific entity
Query.where { has(TestComponent.id) }
     .filter { by(TestComponent.entityVarData).isEqualTo(someEntity) }

// Find entities where entityVar is not equal to a specific entity
Query.where { has(TestComponent.id) }
     .filter { not(by(TestComponent.entityVarData).isEqualTo(someEntity)) }
