Properties

Name	Type	Access	Description
`signNames`	`List<String>`	Read	Returns the names of all signature fields in the document.
`signatureNames`	`List<SignatureName>`	Read	Returns the names of all signature fields (both signed and unsigned).
`blankSignNames`	`List<String>`	Read	Returns the names of unsigned (blank) signature fields.
`containSignature`	`boolean`	Read	Alias for {@link #containsSignature()} matching the C# {@code IsContainSignature()} name.

Methods

Signature	Description
`PdfFileSignature()`	Creates a new empty {@code PdfFileSignature} instance.
`PdfFileSignature(document: Document)`	Creates a {@code PdfFileSignature} bound to the specified document.
`PdfFileSignature(inputFile: String)`	Creates a {@code PdfFileSignature} bound to the PDF at {@code inputFile}.
`bindPdf(inputFile: String)`	Binds a PDF file to this signature facade.
`bindPdf(inputStream: InputStream)`	Binds a PDF from an input stream.
`bindPdf(document: Document)`	Binds an existing {@link Document} to this signature facade.
`getSignNames()` → `List<String>`	Returns the names of all signature fields in the document.
`getSignatureNames(onlyActive: boolean)` → `List<SignatureName>`	Returns the names of all signature fields in the document as
{@link SignatureName} objects with metadata about whether each field is signed.
`getSignatureNames()` → `List<SignatureName>`	Returns the names of all signature fields (both signed and unsigned).
`getBlankSignNames()` → `List<String>`	Returns the names of unsigned (blank) signature fields.
`verifySignature(signatureName: SignatureName)` → `boolean`	Verifies the digital signature of the specified signature field.
`verifySignature(signName: String)` → `boolean`	Verifies the digital signature of the specified signature field.
`verifySignature(signName: String, options: ValidationOptions)` → `boolean`	Verifies the digital signature with validation options.
`verifySignature(signName: String, options: ValidationOptions, result: ValidationResult[])` → `boolean`	Verifies the digital signature with validation options and returns a result.
`verifySignature(signatureName: SignatureName, options: ValidationOptions)` → `boolean`	Verifies the digital signature of the specified {@link SignatureName} with options.
`isContainSignature()` → `boolean`	Alias for {@link #containsSignature()} matching the C# {@code IsContainSignature()} name.
`containsSignature()` → `boolean`	Returns whether the document contains at least one signed signature field.
`isSigned(signName: String)` → `boolean`	Returns whether the specified signature field is signed.
`getReason(signName: String)` → `String`	Returns the signing reason for the specified signature field.
`getLocation(signName: String)` → `String`	Returns the signing location for the specified signature field.
`getSignerName(signName: String)` → `String`	Returns the signer name for the specified signature field.
`getDateTime(signName: String)` → `Date`	Returns the signing date for the specified signature field.
`getContactInfo(signName: String)` → `String`	Returns the contact info for the specified signature field.
`save(outputFile: String)`	Saves the bound document to a file.
`save(outputStream: OutputStream)`	Saves the bound document to an output stream.
`close()`	Closes the signature facade and releases the bound document
(if this facade owns it).
`sign(pageNumber: int, reason: String, contact: String, location: String, visible: boolean, rect: Rectangle, signature: Signature)`	Signs the document by creating a new signature field on the given page.
`sign(fieldName: String, signature: Signature)`	Signs an existing signature field by name.
`removeSignature(signName: String)`	Removes a signature from the specified signature field.
`removeSignature(signName: String, removeField: boolean)`	Removes a signature from the specified signature field.
`containsUsageRights()` → `boolean`	Returns whether the document contains usage rights (UR3 dictionary in the document catalog).
`removeUsageRights()`	Removes usage rights from the document.
`getTotalRevision()` → `int`	Returns the total number of signed revisions in the document.
`getRevision(signName: String)` → `int`	Returns the 1-based revision number for the specified signature field.
`getRevision(signatureName: SignatureName)` → `int`	Returns the 1-based revision number for the specified signature field.
`isCoversWholeDocument(signName: String)` → `boolean`	Returns whether the byte range of the named signature covers the
entire document (i.e.
`coversWholeDocument(signatureName: SignatureName)` → `boolean`	Returns whether the byte range of the named signature covers the
entire document.
`getReason(name: SignatureName)` → `String`	{@link #getReason(String)} overload taking {@link SignatureName}.
`getLocation(name: SignatureName)` → `String`	{@link #getLocation(String)} overload taking {@link SignatureName}.
`getSignerName(name: SignatureName)` → `String`	{@link #getSignerName(String)} overload taking {@link SignatureName}.
`getDateTime(name: SignatureName)` → `Date`	{@link #getDateTime(String)} overload taking {@link SignatureName}.
`getContactInfo(name: SignatureName)` → `String`	{@link #getContactInfo(String)} overload taking {@link SignatureName}.
