Package validation

type Argument ¶

Argument defines the argument for validation

type Argument interface {
    Dependency
    // Arg returns the bytes of the argument
    Arg() []byte
}

type ContextDatum ¶

ContextDatum defines additional data that is passed from the validator into the Validate() invocation

type ContextDatum interface{}

type Dependency ¶

Dependency marks a dependency passed to the Init() method

type Dependency interface{}

type ExecutionFailureError ¶

ExecutionFailureError indicates that the validation failed because of an execution problem, and thus the transaction validation status could not be computed

type ExecutionFailureError struct {
    Reason string
}

func (*ExecutionFailureError) Error ¶

func (e *ExecutionFailureError) Error() string

Error conveys this is an error, and also contains the reason for the error

type Plugin ¶

Plugin validates transactions

type Plugin interface {
    // Validate returns nil if the action at the given position inside the transaction
    // at the given position in the given block is valid, or an error if not.
    Validate(block *common.Block, namespace string, txPosition int, actionPosition int, contextData ...ContextDatum) error

    // Init injects dependencies into the instance of the Plugin
    Init(dependencies ...Dependency) error
}

type PluginFactory ¶

PluginFactory creates a new instance of a Plugin

type PluginFactory interface {
    New() Plugin
}
