Constructor Detail

FileEncryptionProperties

public FileEncryptionProperties(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

encrypted_footer

@Cast(value="bool")
public boolean encrypted_footer()

algorithm

@ByVal
public EncryptionAlgorithm algorithm()

footer_key

@StdString
public String footer_key()

footer_key_metadata

@StdString
public String footer_key_metadata()

file_aad

@StdString
public String file_aad()

column_encryption_properties

@SharedPtr
public ColumnEncryptionProperties column_encryption_properties(@StdString
                                                                           String column_path)

column_encryption_properties

@SharedPtr
public ColumnEncryptionProperties column_encryption_properties(@StdString
                                                                           BytePointer column_path)

is_utilized

@Cast(value="bool")
public boolean is_utilized()

set_utilized

public void set_utilized()

FileEncryptionProperties object can be used for writing one file only. Mark FileEncryptionProperties as utilized once it is used to write a file as the encryption keys will be wiped out upon completion of file writing.

WipeOutEncryptionKeys

public void WipeOutEncryptionKeys()

Upon completion of file writing, the encryption keys will be wiped out (array values set to 0).

DeepClone

@SharedPtr
public FileEncryptionProperties DeepClone(@StdString
                                                      String new_aad_prefix)

FileEncryptionProperties object can be used for writing one file only. (at the end, keys are wiped out in the memory). This method allows to clone identical properties for another file, with an option to update the aadPrefix (if newAadPrefix is null, aadPrefix will be cloned too)

DeepClone

@SharedPtr
public FileEncryptionProperties DeepClone()

DeepClone

@SharedPtr
public FileEncryptionProperties DeepClone(@StdString
                                                      BytePointer new_aad_prefix)

encrypted_columns

@ByVal
 @Cast(value="parquet::ColumnPathToEncryptionPropertiesMap*")
public EncodingIntMap encrypted_columns()
