public abstract class SpatialUnaryDocValuesFunction
extends SpatialDocValuesFunction

A base class for spatial functions that operate on a single geometry input and produce a geometry output, and can receive the incoming geometries from doc-values.

Method Details

resolveType

protected Expression.TypeResolution resolveType()

Description copied from class: Expression

The implementation of Expression.typeResolved(), which is just a caching wrapper around this method. See it's javadoc for what this method should return.

Implementations will rarely interact with the Expression.TypeResolution class directly, instead usually calling the utility methods on TypeResolutions.

Implementations should fail if Expression.childrenResolved() returns false.

Overrides:

resolveType in class Expression

writeTo

public final void writeTo(StreamOutput out)
                   throws IOException

Throws:

IOException

spatialField

public final Expression spatialField()

Specified by:

spatialField in class SpatialDocValuesFunction
