Description copied from interface: ScriptingInvocationService

Invoke the execution of a specified script registered previously by the vault owner, where the script is defined with certain preset routines. It's the general invocation method for external users to call.

Specified by:

callScript in interface ScriptingInvocationService

Type Parameters:

T - String, byte[], JsonNode, Reader

Parameters:

name - The name of script to invoke.

params - The parameters as input to the invocation.

targetDid - The script owner's user did. Skipped when owner calls.

targetAppDid - The script owner's application did. Skipped when owner calls.

resultType - String, byte[], JsonNode, Reader

Returns:

String, byte[], JsonNode, Reader

callScriptUrl

public <T> java.util.concurrent.CompletableFuture<T> callScriptUrl(java.lang.String name,
                                                                   java.lang.String params,
                                                                   java.lang.String targetDid,
                                                                   java.lang.String targetAppDid,
                                                                   java.lang.Class<T> resultType)

Executes a previously registered server side script with a direct URL where the values can be passed as part of the query. Vault owner or external users are allowed to call scripts on someone's vault.

Type Parameters:

T - String, byte[], JsonNode, Reader, Write, OutputStream, Reader, InputStream

Parameters:

name - The call's script name

params - The parameters for the script.

targetDid - The script owner's user did.

targetAppDid - The script owner's application did.

resultType - String, byte[], JsonNode, Reader, Write, OutputStream, Reader, InputStream

Returns:

Result for specific script type

downloadFile

public <T> java.util.concurrent.CompletableFuture<T> downloadFile(java.lang.String transactionId,
                                                                  java.lang.Class<T> resultType)

Description copied from interface: ScriptingInvocationService

Invoke the execution of the script to download a file in the streaming mode. The upload works a bit differently from other executable queries because there are two steps to this executable. First, register a script on the vault, then you call this API actually to download the file

Specified by:

downloadFile in interface ScriptingInvocationService

Type Parameters:

T - Reader or InputStream class

Parameters:

transactionId - The streaming identifier to the upload process

resultType - Reader or InputStream class

Returns:

Reader or InputStream class

uploadFile

public <T> java.util.concurrent.CompletableFuture<T> uploadFile(java.lang.String transactionId,
                                                                java.lang.Class<T> resultType)

Description copied from interface: ScriptingInvocationService

Invoke the execution of the script to upload a file in the streaming mode. The upload works a bit differently from other executable queries because there are two steps to this executable. First, register a script on the vault, then you call this API actually to upload the file

Specified by:

uploadFile in interface ScriptingInvocationService

Type Parameters:

T - Reader or InputStream class

Parameters:

transactionId - The streaming identifier to the upload process

resultType - Reader or InputStream class

Returns:

Reader or InputStream class
