checkPostMultiParameter

public boolean checkPostMultiParameter(java.lang.String name)

This method checks if the parameter is a multivalued one (as returned by a multiple select form) it returns true if so and false if not. It will also return false when the parameter doesn't exist.

See Also:

getPostMultiParameter(java.lang.String), getPostParameter(java.lang.String)

getPostParameters

public java.util.Hashtable getPostParameters()

This method returns the Hashtable containing the POST information. Use of this method is discouraged. Instead use getPostMultiParameter, getPostParameter and checkPostMulitparameter

See Also:

getPostMultiParameter(java.lang.String), getPostParameter(java.lang.String), checkPostMultiParameter(java.lang.String)

getPostParameterBytes

public byte[] getPostParameterBytes(java.lang.String name)
                             throws PostValueToLargeException

This method returns the value of the postparameter as a String. If it is a parameter with multiple values it returns the first one.

Throws:

PostValueToLargeException - will be thrown when the postParameterValue is saved on disk instead of memory.

See Also:

getPostMultiParameter(java.lang.String), checkPostMultiParameter(java.lang.String)

getPostMultiParameter

public java.util.Vector getPostMultiParameter(java.lang.String name)

This method returns the value of the postparameter as a Vector. In case of a parameter with one value, it returns it as a Vector with one element. it laso converts the byte[] into strings

See Also:

checkPostMultiParameter(java.lang.String)

getPostMultiParameter

public java.util.Vector getPostMultiParameter(java.lang.String name,
                                              java.lang.String encoding)

This method returns the value of the postparameter as a Vector. In case of a parameter with one value, it returns it as a Vector with one element. it laso converts the byte[] into strings

See Also:

checkPostMultiParameter(java.lang.String)

getPostParameterFile

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

This method returns the filename containing the postparametervalue If it is a parameter with multiple values it returns the first one.

See Also:

getPostMultiParameter(java.lang.String), checkPostMultiParameter(java.lang.String)

getPostParameter

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

This method returns the value of the postparameter as a String. If it is a parameter with multiple values it returns the first one.

See Also:

getPostMultiParameter(java.lang.String), checkPostMultiParameter(java.lang.String)

readContentLength

public byte[] readContentLength(javax.servlet.http.HttpServletRequest req)

read a block into a array of ContentLenght size from the users networksocket

Parameters:

table - the hashtable that is used as the source for the mapping process

Returns:

byte[] buffer of length defined in the content-length mimeheader

readPostFormData

public boolean readPostFormData(byte[] postbuffer,
                                java.util.Hashtable post_header,
                                java.lang.String line)

read post info from buffer, must be defined in multipart/form-data format.

Parameters:

postbuffer - buffer with the postbuffer information

post_header - hashtable to put the postbuffer information in

readPostFormData

public boolean readPostFormData(java.lang.String formFile,
                                java.util.Hashtable post_header,
                                java.lang.String line)

read post info from buffer, must be defined in multipart/form-data format. Deze methode gaat in het beginsel alleen werken voor het uploaden van 1 bestand De te vinden markers kunnen anders op de scheiding liggen van 2 blokken Het kan dus voorkomen dat de marker op de scheiding ligt van 2 blokken ook dan zal deze methode falen.

Parameters:

postbuffer - buffer with the postbuffer information

post_header - hashtable to put the fromFile information in
