Detailed Description

A container for CompilerError instances generated by the various components of the Bond compiler.

A CompilerErrorBuffer is used by the Lexer, Parser, SemanticAnalyzer and CodeGenerator of the Bond compiler to collect the errors that they detect. The CompilerErrorBuffer provides functionality for printing formatted error messages to an OutputStream.

The size of the buffer is fixed, and no memory allocations are incurred. If the buffer overflows, any additional errors are dropped since they are not considered relevant because they are most likely the consequence of the compiler being confused by the initial set of errors that caused the buffer to fill up.

)

Appends the contents of the given CompilerErrorBuffer to this one.

Parameters

other

The CompilerErrorBuffer whose contents are appended.

GetError()

const CompilerError & Bond::CompilerErrorBuffer::GetError ( size_t  index ) const

inline

Returns the CompilerError at the specified index in the buffer.

Parameters

index

The index of the error to be retrieved.

GetNumErrors()

(

OutputStream &

stream

)

const

Prints a formatted error message for each error to the given OutputStream.

Parameters

stream

The OutputStream to which the error messages are printed.

PushError()

void Bond::CompilerErrorBuffer::PushError	(	CompilerError::Type	type,
		const Token *	context = nullptr,
		const void *	arg0 = nullptr,
