UnsafeProjection¶

UnsafeProjection is an extension of the Projection abstraction for expressions that encode InternalRows to UnsafeRows.

UnsafeProjection: InternalRow =[apply]=> UnsafeRow

Contract¶

Encoding InternalRow as UnsafeRow¶

apply(
  row: InternalRow): UnsafeRow

Encodes the given InternalRow to an UnsafeRow

Implementations¶

InterpretedUnsafeProjection

CodeGeneratorWithInterpretedFallback¶

UnsafeProjection factory object is a CodeGeneratorWithInterpretedFallback of UnsafeProjections (based on Expressions).

CodeGeneratorWithInterpretedFallback[Seq[Expression], UnsafeProjection]

createCodeGeneratedObject¶

createCodeGeneratedObject(
  in: Seq[Expression]): UnsafeProjection

createCodeGeneratedObject is part of the CodeGeneratorWithInterpretedFallback abstraction.

  in: Seq[Expression]): UnsafeProjection

createInterpretedObject is part of the CodeGeneratorWithInterpretedFallback abstraction.

create¶

create(
  fields: Array[DataType]): UnsafeProjection
create(
  expr: Expression): UnsafeProjection
create(
  exprs: Seq[Expression]): UnsafeProjection
create(
  exprs: Seq[Expression],
  inputSchema: Seq[Attribute]): UnsafeProjection
create(
  schema: StructType): UnsafeProjection

create creates an UnsafeProjection for the given BoundReferences.
