        return std::unique_ptr<SkStreamAsset>(this->onFork());
    }

◆ getLength()

size_t SkStreamAsset::getLength ( ) const

overridepure virtual

Returns the total length of the stream. If this cannot be done, returns 0.

Reimplemented from SkStream.

Implemented in SkFILEStream, SkMemoryStream, SkBlockMemoryStream, and SkDWriteFontFileStream.

◆ hasLength()

bool SkStreamAsset::hasLength ( ) const

inlineoverridevirtual

Returns true if this stream can report its total length.

Reimplemented from SkStream.

Definition at line 188 of file SkStream.h.

188{ return true; }

◆ onDuplicate()

SkStreamAsset * SkStreamAsset::onDuplicate ( ) const

overrideprivatepure virtual

Implements SkStreamSeekable.

Implemented in SkFILEStream, SkMemoryStream, SkBlockMemoryStream, SkDWriteFontFileStream, and SkStreamMemory.
