new MemoryBinaryFile(buffer, info?): MemoryBinaryFile

Defined in: packages/core/src/services/binary.service.ts:272

Create a new MemoryBinaryFile

Parameters​

buffer​

string | Buffer<ArrayBufferLike>

Content

challenge?​

optional challenge?: string

Defined in: packages/core/src/services/binary.service.ts:143
