ByMapFilterOperation

ByMapFilterOperation

class ByMapFilterOperation<KeyType, ValueType>(val attrId: Int, val filterBuilder: FilterBuilder)
A class representing a filter operation for Map attributes. It is used to build a filter expression by specifying key-based operations on Map attribute values.
This class provides methods for creating filter nodes that represent operations on Map attributes, such as checking if a map contains a specific key. These filter nodes can then be combined using logical operators (AND, OR) to create complex filtering conditions.
Example:
// Find entities where intToStringMap contains key 42
Query.where { has(TestComponent.id) }
     .filter { by(TestComponent.intToStringMapVarData).containsKey(42) }

// Find entities where stringToIntMap contains either "foo" or "bar" keys
Query.where { has(TestComponent.id) }
     .filter { by(TestComponent.stringToIntMapVarData).containsKey("foo") or
               by(TestComponent.stringToIntMapVarData).containsKey("bar") }
