Expr.VectorInputBinding (druid-processing 28.0.0 API)

All Superinterfaces:

Expr.InputBindingInspector, Expr.VectorInputBindingInspector

All Known Implementing Classes:

ExpressionVectorInputBinding

Enclosing interface:

Expr
```
public static interface Expr.VectorInputBinding
extends Expr.VectorInputBindingInspector
```
Mechanism to supply batches of input values to a ExprVectorProcessor for optimized processing. Mirrors the vectorized column selector interfaces, and includes ExpressionType information about all input bindings which exist

    Returns an integer that uniquely identifies the current position of the underlying vector offset, if this binding is backed by a segment. This is useful for caching: it is safe to assume nothing has changed in the offset so long as the id remains the same. See also: ReadableVectorOffset (in druid-processing)
