## org.apache.coyote
Class Request

    java.lang.Object
      org.apache.coyote.Request

public final class Request
extends java.lang.Object

This is a low-level, efficient representation of a server request. Most fields are GC-free, expensive operations are delayed until the user code needs the information. Processing is delegated to modules, using a hook mechanism. This class is not intended for user code - it is used internally by tomcat for processing the request in the most efficient way. Users ( servlets ) can access the information using a facade, which provides the high-level view of the request. For lazy evaluation, the request uses the getInfo() hook. The following ids are defined:

- req.encoding - returns the request encoding
- req.attribute - returns a module-specific attribute ( like SSL keys, etc ).

Tomcat defines a number of attributes:

- "org.apache.tomcat.request" - allows access to the low-level request object in trusted applications

Constructor Detail

### Request

    public Request()

Method Detail

### instanceId

    public MessageBytes instanceId()

  Get the instance id (or JVM route). Curently Ajp is sending it with each request. In future this should be fixed, and sent only once ( or 'negociated' at config time so both tomcat and apache share the same name.

  Returns:
    the instance id

### getMimeHeaders

    public MimeHeaders getMimeHeaders()

### getURLDecoder

    public UDecoder getURLDecoder()

### scheme

    public MessageBytes scheme()

### method

    public MessageBytes method()

### unparsedURI

    public MessageBytes unparsedURI()

### requestURI

    public MessageBytes requestURI()

### decodedURI

    public MessageBytes decodedURI()

### query

    public MessageBytes query()

### queryString

    public MessageBytes queryString()

### protocol

    public MessageBytes protocol()

### serverName

    public MessageBytes serverName()

  Return the buffer holding the server name, if any. Use isNull() to check if there is no value set. This is the "virtual host", derived from the Host: header.

### getServerPort

    public int getServerPort()

### setServerPort

    public void setServerPort(int serverPort)

### remoteAddr

    public MessageBytes remoteAddr()

### remoteHost

    public MessageBytes remoteHost()

### localName

    public MessageBytes localName()

### localAddr

    public MessageBytes localAddr()

### getRemotePort

    public int getRemotePort()

### setRemotePort

    public void setRemotePort(int port)

### getLocalPort

    public int getLocalPort()

### setLocalPort

    public void setLocalPort(int port)

### getCharacterEncoding

    public java.lang.String getCharacterEncoding()

  Get the character encoding used for this request.

### setCharacterEncoding

    public void setCharacterEncoding(java.lang.String enc)

### setContentLength

    public void setContentLength(int len)

### getContentLength

    public int getContentLength()

### getContentLengthLong

    public long getContentLengthLong()

### getContentType

    public java.lang.String getContentType()

### setContentType

### contentType

    public MessageBytes contentType()

### setContentType

    public void setContentType(MessageBytes mb)

### getHeader

    public java.lang.String getHeader(java.lang.String name)

### getResponse

    public Response getResponse()

### setResponse

    public void setResponse(Response response)

    public void action(ActionCode actionCode,
                       java.lang.Object param)

### getCookies

    public Cookies getCookies()

### getParameters

    public Parameters getParameters()

### setAttribute

    public void setAttribute(java.lang.String name,
                             java.lang.Object o)

### getAttributes

    public java.util.HashMap getAttributes()

### getAttribute

    public java.lang.Object getAttribute(java.lang.String name)

### getRemoteUser

    public MessageBytes getRemoteUser()

### getAuthType

    public MessageBytes getAuthType()

### getInputBuffer

    public InputBuffer getInputBuffer()

### setInputBuffer

    public void setInputBuffer(InputBuffer inputBuffer)

### doRead

    public int doRead(ByteChunk chunk)
               throws java.io.IOException

  Read data from the input buffer and put it into a byte chunk. The buffer is owned by the protocol implementation - it will be reused on the next read. The Adapter must either process the data in place or copy it to a separate buffer if it needs to hold it. In most cases this is done during byte->char conversions or via InputStream. Unlike InputStream, this interface allows the app to process data in place, without copy.

  Throws:
    `java.io.IOException`

### getStartTime

    public long getStartTime()

### setStartTime

### updateCounters

    public void updateCounters()

### getRequestProcessor
