Public Constructors

public BufferedHeader (CharArrayBuffer buffer)

Since: API Level 1

Creates a new header from a buffer. The name of the header will be parsed immediately, the value only if it is accessed.

Parameters
buffer the buffer containing the header to represent
Throws
ParseException in case of a parse error

Public Methods

public Object clone ()

Since: API Level 1

Creates and returns a copy of this Object. The default implementation returns a so-called "shallow" copy: It creates a new instance of the same class and then copies the field values (including object references) from this instance to the new instance. A "deep" copy, in contrast, would also recursively clone nested objects. A subclass that needs to implement this kind of cloning should call super.clone() to create the new instance and then create deep copies of the nested, mutable objects.

Returns
  • a copy of this object.
Throws
CloneNotSupportedException

public CharArrayBuffer getBuffer ()

Since: API Level 1

Obtains the buffer with the formatted header. The returned buffer MUST NOT be modified.

Returns
  • the formatted header, in a buffer that must not be modified

public HeaderElement[] getElements ()

Since: API Level 1

Throws
ParseException

public String getName ()

Since: API Level 1

public String getValue ()

Since: API Level 1

public int getValuePos ()

Since: API Level 1

Obtains the start of the header value in the buffer. By accessing the value in the buffer, creation of a temporary string can be avoided.

Returns
  • index of the first character of the header value in the buffer returned by getBuffer.

public String toString ()

Since: API Level 1

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation simply concatenates the class name, the '@' sign and a hexadecimal representation of the object's hashCode(), that is, it is equivalent to the following expression: 

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
  • a printable representation of this object.
