Detailed Description

Similar to FMemoryWriter, but able to internally manage the memory for the buffer.

◆ FBufferWriter()

FBufferWriter::FBufferWriter ( void * Data,
int64 Size,
EBufferWriterFlags InFlags = EBufferWriterFlags::None )

Member Function Documentation

◆ AtEnd()

bool FBufferWriter::AtEnd ( )
inlinevirtual

Returns true if the current location within the backing data storage is at the end, always returns false if there is no storage.

Reimplemented from FArchive.

Definition at line 102 of file BufferWriter.h.

◆ Close()

bool FBufferWriter::Close ( )
inlinevirtual

Attempts to close and finalize any handles used for backing data storage, returns true if it succeeded.

Reimplemented from FArchive.

Definition at line 52 of file BufferWriter.h.

+ Here is the call graph for this function:
+ Here is the caller graph for this function:

◆ GetArchiveName()

virtual FString FBufferWriter::GetArchiveName ( ) const
inlinevirtual

Returns the name of the Archive. Useful for getting the name of the package a struct or object is in when a loading error occurs.

This is overridden for the specific Archive Types

Reimplemented from FArchive.

Definition at line 112 of file BufferWriter.h.

◆ GetWriterData()

void * FBufferWriter::GetWriterData ( )
inline

Definition at line 114 of file BufferWriter.h.

◆ Seek()

void FBufferWriter::Seek ( int64 InPos)
inlinevirtual

Attempts to set the current offset into backing data storage, this will do nothing if there is no storage.

Reimplemented from FArchive.

Definition at line 96 of file BufferWriter.h.

◆ Serialize()

void FBufferWriter::Serialize ( void * Data,
int64 Num )
inlinevirtual

Reimplemented from FArchive.

Definition at line 61 of file BufferWriter.h.

+ Here is the call graph for this function:

◆ Tell()

int64 FBufferWriter::Tell ( )
inlinevirtual

Returns the current location within the backing data storage, which can possibly be passed to Seek later to restore a read/write location. If this returns -1, there is no backing data storage and Seek will not function.

Reimplemented from FArchive.

Definition at line 88 of file BufferWriter.h.

◆ TotalSize()

int64 FBufferWriter::TotalSize ( )
inlinevirtual

Returns total size of the backing data storage.

Reimplemented from FArchive.

Definition at line 92 of file BufferWriter.h.
