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 at 64 errors, 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.

Constructor & Destructor Documentation

CompilerErrorBuffer()

Bond::CompilerErrorBuffer::CompilerErrorBuffer

(

)

Default constructs an empty CompilerErrorBuffer object.

Member Function Documentation

CopyFrom()

void Bond::CompilerErrorBuffer::CopyFrom

(

const CompilerErrorBuffer &

other

)

Appends the contents of the given CompilerErrorBuffer to this one. Errors that do not fit are dropped.

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()

size_t Bond::CompilerErrorBuffer::GetNumErrors ( ) const

inline

Returns the number of errors in the buffer.

HasErrors()

bool Bond::CompilerErrorBuffer::HasErrors ( ) const

inline

Returns whether the buffer contains any errors.

Print()

void Bond::CompilerErrorBuffer::Print

(

OutputStream &

stream

)

const

Prints a formatted error message for each error, each followed by a newline, 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,
		const void *	arg1 = nullptr )

Constructs a CompilerError object with the given type and pointer arguments to format the error message and adds it to the buffer, unless the buffer is full.

CompilerError::CompilerError

PushErrorInt()

void Bond::CompilerErrorBuffer::PushErrorInt	(	CompilerError::Type	type,
		const Token *	context = nullptr,
		intptr_t	arg0 = 0,
		intptr_t	arg1 = 0 )

Constructs a CompilerError object with the given type and integer arguments to format the error message and adds it to the buffer, unless the buffer is full.

CompilerError::CompilerError

Reset()

void Bond::CompilerErrorBuffer::Reset

(

)

Clears the contents of the error buffer.

Truncate()

void Bond::CompilerErrorBuffer::Truncate ( size_t numErrors )

inline

Discards the errors pushed after the buffer contained the given number of errors.

Parameters

numErrors

The number of errors to retain. Has no effect if it is not smaller than the current number of errors.
