Direct Known Subclasses:

ArrayReader, MapReader

public abstract class AvroStructureReader
extends AvroReadContext

Base class for handlers for Avro structured types (or in some cases, scalar types that need to be exposed in unified way similar to structured types).

Method Summary

Modifier and Type	Method	Description
protected <T> T	_throwUnsupported()
boolean	consumesNoContent()	Method that may be called to check if the values "read" by this reader are zero-length, that is, consume no content: most common example being Record with no fields.
abstract AvroStructureReader	newReader(AvroReadContext parent, AvroParserImpl parser)	Method for creating actual instance to use for reading (initial instance constructed is so-called blueprint).
abstract tools.jackson.core.JsonToken	nextToken()
abstract void	skipValue(AvroParserImpl parser)	Alternative to nextToken() which will simply skip the full value.

Constructor Details

AvroStructureReader

protected AvroStructureReader(AvroReadContext parent,
 int type,
 String typeId)

Method Details

consumesNoContent

public boolean consumesNoContent()

Method that may be called to check if the values "read" by this reader are zero-length, that is, consume no content: most common example being Record with no fields.

Note: Arrays can not return true as they need to encode length even for "empty" arrays.

newReader

public abstract AvroStructureReader newReader(AvroReadContext parent,
 AvroParserImpl parser)

Method for creating actual instance to use for reading (initial instance constructed is so-called blueprint).

nextToken

public abstract tools.jackson.core.JsonToken nextToken()
                                                throws IOException

Specified by:

nextToken in class AvroReadContext

Throws:

IOException

skipValue

public abstract void skipValue(AvroParserImpl parser)
                        throws IOException

Alternative to nextToken() which will simply skip the full value.

Specified by:

skipValue in class AvroReadContext

Throws:

IOException

throwIllegalState

protected void throwIllegalState(int state)

_throwUnsupported

protected <T> T _throwUnsupported()
