Member Function Documentation

clear()

void Quotient::FixedBufferBase::clear

(

copyToByteArray()

QByteArray Quotient::FixedBufferBase::copyToByteArray ( QByteArray::size_type  untilPos = -1 ) const

inline

Copy the contents of the buffer to a QByteArray.

Unlike viewAsByteArray(), this function actually copies the buffer to non-secure memory.

size()

toBase64() [1/2]

QByteArray Quotient::FixedBufferBase::toBase64 ( ) const

inline

Definition at line 183 of file e2ee_common.h.

toBase64() [2/2]

QByteArray Quotient::FixedBufferBase::toBase64 ( QByteArray::Base64Options  options ) const

inline

Definition at line 184 of file e2ee_common.h.

viewAsByteArray()

QByteArray Quotient::FixedBufferBase::viewAsByteArray ( ) const

inline

Access the bytes of the fixed buffer via QByteArray interface.

This uses QByteArray::fromRawData() to create a QByteArray object that refers to the original fixed buffer, without copying.

Warning

the lifetime of the returned QByteArray should not exceed the lifetime of the underlying buffer; in particular, you should never try using the result of viewAsByteArray() as a return value of your function
