Types

type BufferPool 

type BufferPool struct {
	// contains filtered or unexported fields
}

BufferPool implements a pool of bytes.Buffers in the form of a bounded channel.

func NewBufferPool 

func NewBufferPool(size int) (bp *BufferPool)

NewBufferPool creates a new BufferPool bounded to the given size.

func (*BufferPool) Get 

func (this *BufferPool) Get() (buffer *bytes.Buffer)

Get gets a Buffer from the BufferPool, or creates a new one if none are available in the pool.

func (*BufferPool) Set 

func (this *BufferPool) Set(buffer *bytes.Buffer)

Set returns the given Buffer to the BufferPool.

type ExecHelper 

type ExecHelper struct{}

func NewExecHelper 

func NewExecHelper() *ExecHelper

func (*ExecHelper) Run 

func (this *ExecHelper) Run(name string, args ...string) ([]byte, error)

type FileHelper 

type FileHelper struct{}

func NewFileHelper 

func NewFileHelper() *FileHelper

func (*FileHelper) CopyFile 

func (this *FileHelper) CopyFile(src, dst string) (int64, error)

Copy copies from src to dst until either EOF is reached on src or an error occurs. It returns the number of bytes copied and the first error encountered while copying, if any.

A successful Copy returns err == nil, not err == EOF. Because Copy is defined to read from src until EOF, it does not treat an EOF from Read as an error to be reported.

If src implements the WriterTo interface, the copy is implemented by calling src.WriteTo(dst). Otherwise, if dst implements the ReaderFrom interface, the copy is implemented by calling dst.ReadFrom(src).

func (*FileHelper) GZipFile 

func (this *FileHelper) GZipFile(src, dst string) error

Use gzip to compress src to dst until either EOF is reached or an error occurs.
