Type Members

1.  case class AndOp(children: Seq[BaseOp]) extends NonLeafOp with NaryOp with Product with Serializable

   The following ops represent boolean logic related operations.

   The following ops represent boolean logic related operations. The (logically) supported operations are: "&&", "||", "!"

2.  trait BaseOp extends AnyRef

   The base operation and the associated json type and sub type tagging needed to convert case class hierarchy into json.

   The base operation and the associated json type and sub type tagging needed to convert case class hierarchy into json.

   If we add support for a new operation, we need to add an entry below which will tag the operation with the given name.

   @JsonTypeInfo() @JsonSubTypes()

3.  trait BinaryOp extends AnyRef
4.  case class ColumnOp(name: String, valueType: String) extends LeafOp with Product with Serializable

   Represents a column.

   Represents a column.

   name

   The name of the column as it appears in the table.

   valueType

   The type of column's value. During evaluation, the name of the column is used to resolve its value in the evaluation context.

5.  case class EqualOp(children: Seq[LeafOp]) extends NonLeafOp with BinaryOp with Product with Serializable

   The following ops represent comparison operations on their children.

   The following ops represent comparison operations on their children. The (logically) supported operations are: "=", "<", "<=", ">", ">="

   We only implement "=" and "<", and represent all others in terms of these two.

   children

   Expected size is 2.

6.  case class EvalContext(partitionValues: Map[String, String]) extends Product with Serializable

   The evaluation context in which operations will be evaluated.

   The evaluation context in which operations will be evaluated.

   partitionValues

   The partition values associated with parquet files.

12.  case class LessThanOrEqualOp(children: Seq[LeafOp]) extends NonLeafOp with BinaryOp with Product with Serializable
13.  case class LiteralOp(value: String, valueType: String) extends LeafOp with Product with Serializable

    Represents a literal.

    Represents a literal.

    value

    The value of this literal as a string.

    valueType

    The type of value.
