public class DataSenderWriter
extends java.io.OutputStreamWriter

A Writer used as a marker to indicate that JSON strings should not be base 64 encoded. JSONStreamAware objects should call getJsonifiedOptionallyCompressedEncodedString(Object, Writer)

getJsonifiedOptionallyCompressedEncodedString

public static java.lang.Object getJsonifiedOptionallyCompressedEncodedString(java.lang.Object data,
                                                                             java.io.Writer writer)

Returns a JSON string that will be deflate compressed and base 64 encoded if AgentConfigImpl.SIMPLE_COMPRESSION_PROPERTY is disabled (default). The JSON string will be returned raw and uncompressed otherwise.

Parameters:

data - the data to be serialized to JSON

writer - the writer to use

Returns:

the compressed or uncompressed json value for the data passed in

getJsonifiedOptionallyCompressedEncodedString

public static java.lang.Object getJsonifiedOptionallyCompressedEncodedString(java.lang.Object data,
                                                                             java.io.Writer writer,
                                                                             int compressionLevel)

Returns a JSON string that will be deflate compressed and base 64 encoded if AgentConfigImpl.SIMPLE_COMPRESSION_PROPERTY is disabled (default). The JSON string will be returned raw and uncompressed otherwise.

Parameters:

data - the data to be serialized to JSON

writer - the writer to use

compressionLevel - the compression level to use (if the data is compressed)

Returns:

the compressed or uncompressed json value for the data passed in

getJsonifiedOptionallyCompressedEncodedString

public static java.lang.Object getJsonifiedOptionallyCompressedEncodedString(java.lang.Object data,
                                                                             java.io.Writer writer,
                                                                             int compressionLevel,
                                                                             int resultSizeLimitInBytes)

Returns a JSON string that will be deflate compressed and base 64 encoded if AgentConfigImpl.SIMPLE_COMPRESSION_PROPERTY is disabled (default). The JSON string will be returned raw and uncompressed otherwise. Additionally, the payload will be compressed in all cases to compare its size against the passed in limit. If the result is larger than the limit then a null value will be returned indicating that the JSON is larger than the limit. If the compressed result is under the limit then the simple_compression rules from the first paragraph apply and either the compressed or uncompressed JSON will be returned.

Parameters:

data - the data to be serialized to JSON

writer - the writer to use

compressionLevel - the compression level to use (if the data is compressed or to check size limit)

resultSizeLimitInBytes - the maximum size in bytes of the compressed version of the result

Returns:

null if the compressed result is over the limit, otherwise the serialized JSON will be returned.

toJSONString

public static java.lang.String toJSONString(java.lang.Object obj)

Get a JSON string for the object.
