Constructor Detail

DefaultWebSocketFrame

public DefaultWebSocketFrame()

Creates a new empty text frame.

DefaultWebSocketFrame

public DefaultWebSocketFrame(String textData)

Creates a new text frame from with the specified string.

DefaultWebSocketFrame

public DefaultWebSocketFrame(int type,
                             ChannelBuffer binaryData)

Creates a new frame with the specified frame type and the specified data.

Parameters:

type - the type of the frame. 0 is the only allowed type currently.

binaryData - the content of the frame. If (type & 0x80 == 0), it must be encoded in UTF-8.

Throws:

IllegalArgumentException - if If (type & 0x80 == 0) and the data is not encoded in UTF-8

Method Detail

getType

public int getType()

Description copied from interface: WebSocketFrame

Returns the type of this frame. 0x00-0x7F means a text frame encoded in UTF-8, and 0x80-0xFF means a binary frame. Currently, 0 is the only allowed type according to the specification.

Specified by:

getType in interface WebSocketFrame

isText

public boolean isText()

Description copied from interface: WebSocketFrame

Returns true if and only if the content of this frame is a string encoded in UTF-8.

Specified by:

isText in interface WebSocketFrame

isBinary

public boolean isBinary()

Description copied from interface: WebSocketFrame

Returns true if and only if the content of this frame is an arbitrary binary data.

Specified by:

isBinary in interface WebSocketFrame

getBinaryData

public ChannelBuffer getBinaryData()

Description copied from interface: WebSocketFrame

Returns the content of this frame as-is, with no UTF-8 decoding.

Specified by:

getBinaryData in interface WebSocketFrame

getTextData

public String getTextData()

Description copied from interface: WebSocketFrame

Converts the content of this frame into a UTF-8 string and returns the converted string.

Specified by:

getTextData in interface WebSocketFrame

setData

public void setData(int type,
                    ChannelBuffer binaryData)

Description copied from interface: WebSocketFrame

Sets the type and the content of this frame.

Specified by:

setData in interface WebSocketFrame

Parameters:

type - the type of the frame. 0 is the only allowed type currently.

binaryData - the content of the frame. If (type & 0x80 == 0), it must be encoded in UTF-8.

toString

public String toString()

Description copied from interface: WebSocketFrame

Returns the string representation of this frame. Please note that this method is not identical to WebSocketFrame.getTextData().

Specified by:

toString in interface WebSocketFrame

Overrides:

toString in class Object
