public SignedData(@NotNull
                  SerializedBytes<T> raw,
                  @NotNull
                  net.corda.core.crypto.DigitalSignature.WithKey sig)

A serialized piece of data and its signature. Enforces signature validity in order to deserialize the data contained within.

Parameters:

Throws:

IllegalArgumentException - if the data is invalid.

getRaw

@NotNull
public SerializedBytes<T> getRaw()

the raw serialized data.

getSig

@NotNull
public net.corda.core.crypto.DigitalSignature.WithKey getSig()

the
