public LedgerValidationRequest(java.lang.String assetId,
                               int startAge,
                               int endAge,
                               java.lang.String entityId,
                               int keyVersion,
                               byte[] signature)

Constructs a LedgerValidationRequest with the specified asset id, entity ID, key version, signature of the request, and client-side proof.

Parameters:

assetId - an id of an asset

startAge - an age to be validated from

endAge - an age to be validated to

entityId - an entity ID

keyVersion - the version of a digital signature certificate or a HMAC secret key.

signature - a signature of the request

Method Detail

getAssetId

public java.lang.String getAssetId()

Returns the id of the asset.

Returns:

the id of the asset

getStartAge

public int getStartAge()

Returns the age of the asset to be validated from.

Returns:

the age of the asset to be validated from

getEndAge

public int getEndAge()

Returns the age of the asset to be validated to.

Returns:

the age of the asset to be validated to

getSignature

public byte[] getSignature()

Returns the signature of the request.

Returns:

the signature of the request

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class AbstractRequest

Returns:

a hash code value for this object.

equals

public boolean equals(java.lang.Object o)

Indicates whether some other object is "equal to" this object. The other object is considered equal if it is the same instance or if:

• both super class instances are equal and
• it is also an LedgerValidationRequest and
• both instances have the same asset id, signature and proof.

Overrides:

equals in class AbstractRequest

Parameters:

o - an object to be tested for equality

Returns:

true if the other object is "equal to" this object otherwise false

validateWith

public void validateWith(com.scalar.dl.ledger.crypto.SignatureValidator validator)

Validates if the request is not tampered.

Specified by:

validateWith in class AbstractRequest

Parameters:

validator - a SignatureValidator

Throws:

com.scalar.dl.ledger.exception.SignatureException - if the request is invalid.

serialize

public static byte[] serialize(java.lang.String assetId,
                               int startAge,
                               int endAge,
                               java.lang.String entityId,
                               int keyVersion)
