Class TypeMatcher

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.arrow.TypeMatcher

All Implemented Interfaces:

AutoCloseable

@Namespace(value="arrow::compute")
 @Properties(inherit=arrow.class)
public class TypeMatcher
extends Pointer

\brief An type-checking interface to permit customizable validation rules for use with InputType and KernelSignature. This is for scenarios where the acceptance is not an exact type instance, such as a TIMESTAMP type for a specific TimeUnit, but permitting any time zone.

Constructor Detail

TypeMatcher

public TypeMatcher(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

Matches

@Cast(value="bool")
public boolean Matches(@Const @ByRef
                                            DataType type)

\brief Return true if this matcher accepts the data type.

ToString

@StdString
public String ToString()

\brief A human-interpretable string representation of what the type matcher checks for, usable when printing KernelSignature or formatting error messages.

Equals

@Cast(value="bool")
public boolean Equals(@Const @ByRef
                                           TypeMatcher other)

\brief Return true if this TypeMatcher contains the same matching rule as the other. Currently depends on RTTI.
