Package org.apache.avro.generic

A generic representation for Avro data.

This representation is best for applications which deal with dynamic data, whose schemas are not known until runtime.

Avro schemas are mapped to Java types as follows:

Schema records are implemented as org.apache.avro.generic.GenericRecord.
Schema enums are implemented as org.apache.avro.generic.GenericEnumSymbol.
Schema arrays are implemented as java.util.Collection.
Schema maps are implemented as java.util.Map.
Schema fixed are implemented as org.apache.avro.generic.GenericFixed.
Schema strings are implemented as java.lang.CharSequence.
Schema bytes are implemented as java.nio.ByteBuffer.
Schema ints are implemented as java.lang.Integer.
Schema longs are implemented as java.lang.Long.
Schema floats are implemented as java.lang.Float.
Schema doubles are implemented as java.lang.Double.
Schema booleans are implemented as java.lang.Boolean.
