java.lang.Object com.fasterxml.jackson.core.io.IOContext
public final class IOContext
To limit number of configuration and state objects to pass, all contextual objects that need to be passed by the factory to readers and writers are combined under this object. One instance is created for each reader and writer.
Field Summary | |
---|---|
protected BufferRecycler |
_bufferRecycler
Recycler used for actual allocation/deallocation/reuse |
protected char[] |
_concatCBuffer
Reference to the buffer allocated for buffering it for output, before being encoded: generally this means concatenating output, then encoding when buffer fills up. |
protected JsonEncoding |
_encoding
Encoding used by the underlying stream, if known. |
protected boolean |
_managedResource
Flag that indicates whether underlying input/output source/target object is fully managed by the owner of this context (parser or generator). |
protected char[] |
_nameCopyBuffer
Reference temporary buffer Parser instances need if calling app decides it wants to access name via 'getTextCharacters' method. |
protected byte[] |
_readIOBuffer
Reference to the allocated I/O buffer for low-level input reading, if any allocated. |
protected Object |
_sourceRef
Reference to the source object, which can be used for displaying location information |
protected char[] |
_tokenCBuffer
Reference to the buffer allocated for tokenization purposes, in which character input is read, and from which it can be further returned. |
protected byte[] |
_writeEncodingBuffer
Reference to the allocated I/O buffer used for low-level encoding-related buffering. |
