@DoNotImplement interface AttachmentConstraint
Constrain which contract-code-containing attachment can be used with a Contract.
isSatisfiedBy |
Returns whether the given contract attachment can be used with the ContractState associated with this constraint object. abstract fun isSatisfiedBy(attachment: Attachment): Boolean |
AlwaysAcceptAttachmentConstraint |
An AttachmentConstraint where isSatisfiedBy always returns true. object AlwaysAcceptAttachmentConstraint : AttachmentConstraint |
AutomaticHashConstraint |
object |
AutomaticPlaceholderConstraint |
This AttachmentConstraint is a convenience class that acts as a placeholder and will be automatically resolved by the platform when set on an output state. It is the default constraint of all output states. object AutomaticPlaceholderConstraint : AttachmentConstraint |
HashAttachmentConstraint |
An AttachmentConstraint that verifies by hash. The state protected by this constraint can only be used in a transaction created with that version of the jar. And a receiving node will only accept it if a cordapp with that hash has (is) been deployed on the node. data class HashAttachmentConstraint : AttachmentConstraint |
SignatureAttachmentConstraint |
An AttachmentConstraint that verifies that the attachment has signers that fulfil the provided PublicKey. See: Signature Constraints data class SignatureAttachmentConstraint : AttachmentConstraint |
WhitelistedByZoneAttachmentConstraint |
An AttachmentConstraint that verifies that the hash of the attachment is in the network parameters whitelist. See: net.corda.core.node.NetworkParameters.whitelistedContractImplementations It allows for centralized control over the cordapps that can be used. object WhitelistedByZoneAttachmentConstraint : AttachmentConstraint |
