Class GlueFieldLexer

java.lang.Object

com.amazonaws.athena.connector.lambda.metadata.glue.GlueFieldLexer

public class GlueFieldLexer
extends Object

This class makes use of GlueTypeParser to tokenize the definition of the field. For basic fields, the Lexer's job is straight forward but for complex types it is more involved.
