Method Details

findGeometryMember

public static Struct.StructMember findGeometryMember(@NonNull
 @NonNull Struct source,
 TupleUtils.FindOption option)

findGeometryMember

public static Struct.StructMember findGeometryMember(@NonNull
 @NonNull Struct source,
 @NonNull
 @NonNull TupleUtils.FindOption option,
 @NonNull
 @NonNull Supplier<RuntimeException> failedHandler)

Look in the given struct for a member with type Geom.

Parameters:

source - the type to search through

option - flag whether at least on is required. If set to false, no exception is thrown if no Geom member is found.

Throws:

IllegalArgumentException - if either no or more than one Geom type was found in the given struct

findRequiredGeometryMember

public static Struct.StructMember findRequiredGeometryMember(Struct struct)

Convenience version of findGeometryMember where required flag is set to true

hasGeometryMember

public static boolean hasGeometryMember(Struct struct)

Convenience version to check if the struct has a geometry member

getContentSummary

public static String getContentSummary(Tuple tuple)

Returns:

a concise summary of the tuple's content. Values may be shortened, or in the case of geometries will be excluded completely.
