This file defines the StringMap class.

Provides read only access to a subclass of BinaryStream.

Error readInteger(T &Dest)

Read an integer of the specified endianness into Dest and update the stream's offset.

LLVM_ABI Error readFixedString(StringRef &Dest, uint32_t Length)

Read a Length byte string into Dest.

Provides write only access to a subclass of WritableBinaryStream.

Error writeInteger(T Value)

Write the integer Value to the underlying stream in the specified endianness.

LLVM_ABI Error writeFixedString(StringRef Str)

Write the string Str to the underlying stream without a null terminator.

Lightweight error class with error context and mandatory checking.

static ErrorSuccess success()

Create a success value.

StringMap - This is an unconventional map that is specialized for handling keys that are "strings",...

StringRef - Represent a constant reference to a string, i.e.
