The existing output format was not complete and so was deleted to avoid it becoming a tech debt. We can always resurrect it at a later point.

Blob Inspector
There are many benefits to having a custom binary serialisation format (see serialization
for details) but one disadvantage is the inability to view the contents in a human-friendly manner. The blob inspector tool alleviates this issue by allowing the contents of a binary blob file (or URL end-point) to be output in either YAML or JSON. It uses JacksonSupport
to do this (see json
).
The latest version of the tool can be downloaded from here.
To run simply pass in the file or URL as the first parameter:
java -jar blob-inspector.jar <file or URL>
Use the --help
flag for a full list of command line options.
SerializedBytes` ~~~~~~~~~~~~~~~~~~ One thing to note is that the binary blob may contain embedded
SerializedBytesobjects. Rather than printing these out as a Base64 string, the blob inspector will first materialise them into Java objects and then output those. You will see this when dealing with classes such as
SignedDataor other structures that attach a signature, such as the
nodeInfo-*files or the
network-parametersfile in the node's directory. For example, the output of a node-info file may look like: .. container:: codeset .. sourcecode:: yaml net.corda.nodeapi.internal.SignedNodeInfo --- raw: class: "net.corda.core.node.NodeInfo" deserialized: addresses: - "localhost:10011" legalIdentitiesAndCerts: - "O=BankOfCorda, L=New York, C=US" platformVersion: 4 serial: 1527074180971 signatures: - !!binary | dmoAnnzcv0MzRN+3ZSCDcCJIAbXnoYy5mFWB3Nijndzu/dzIoYdIawINXbNSY/5z2XloDK01vZRV TreFZCbZAg== .. sourcecode:: json net.corda.nodeapi.internal.SignedNodeInfo { "raw" : { "class" : "net.corda.core.node.NodeInfo", "deserialized" : { "addresses" : [ "localhost:10011" ], "legalIdentitiesAndCerts" : [ "O=BankOfCorda, L=New York, C=US" ], "platformVersion" : 4, "serial" : 1527074180971 } }, "signatures" : [ "dmoAnnzcv0MzRN+3ZSCDcCJIAbXnoYy5mFWB3Nijndzu/dzIoYdIawINXbNSY/5z2XloDK01vZRVTreFZCbZAg==" ] } Notice the file is actually a serialised
SignedNodeInfoobject, which has a
rawproperty of type
SerializedBytes<NodeInfo>. This property is materialised into a
NodeInfoand is output under the
deserialized`` field.
