All Implemented Interfaces:

android.os.Parcelable
```
public final class DigitalSignatureMetadata
 implements Parcelable
                    
```
DigitalSignatureMetadata contains all metadata like appearance config, algorithm and other configuration needed for signing data

Method Summary

Modifier and Type	Method	Description
`final SignatureAppearance`	`getSignatureAppearance()`	SignatureAppearance that will be used to determine how the signature looks once signing is done.
`final Integer`	`getEstimatedSize()`	The estimated size is part of the size that will be reserved in the PDF document before digitally signing it.
`final HashAlgorithm`	`getHashAlgorithm()`	Returns the algorithm to hash the document before the signature is created.
`final String`	`getReason()`	The reason why the document was signed.
`final String`	`getLocation()`	The place where the document was signed.
`final TimestampData`	`getTimestampData()`	timestampData is an optional field, it “upgrades” the signature to PAdES B-T level to include a cryptographic timestamp token to prove that the signed document existed at a given point in time.
`final BiometricSignatureData`	`getBiometricData()`	BiometricSignatureData that will be written to the digital signature.
`Unit`	`writeToParcel(Parcel parcel, Integer flags)`
`Integer`	`describeContents()`

- Method Detail
  - getSignatureAppearance
```
 final SignatureAppearance getSignatureAppearance()
```
    SignatureAppearance that will be used to determine how the signature looks once signing is done.
  - getEstimatedSize
```
 final Integer getEstimatedSize()
```
    The estimated size is part of the size that will be reserved in the PDF document before digitally signing it. This size corresponds only to the /Contents field of the signature field, that is, the signature container. Core will actually reserve a bigger space to make room for implementation details (the /ByteRange field, the fact that a signature is hex-encoded in a PDF, etc.). A big estimated size will possibly make the signed document bigger than necessary, but a too small one will cause the signing process to fail. The value will be clamped to the nearest even value between 0 and 256 KB (262144 bytes). If not set, the default is 32 KB (32768 bytes).
  - getHashAlgorithm
```
 final HashAlgorithm getHashAlgorithm()
```
    Returns the algorithm to hash the document before the signature is created. Defaults to SHA-256.
  - getReason
```
 final String getReason()
```
    The reason why the document was signed.
  - getLocation
```
 final String getLocation()
```
    The place where the document was signed.
  - getTimestampData
```
 final TimestampData getTimestampData()
```
    timestampData is an optional field, it “upgrades” the signature to PAdES B-T level to include a cryptographic timestamp token to prove that the signed document existed at a given point in time.
  - getBiometricData
```
 final BiometricSignatureData getBiometricData()
```
    BiometricSignatureData that will be written to the digital signature. May be null.
  - writeToParcel
```
 Unit writeToParcel(Parcel parcel, Integer flags)
```
  - describeContents
```
 Integer describeContents()
```
