      org.simpleframework.http.parse.ContentDispositionParser

All Implemented Interfaces:

ContentDisposition

Constructor Detail

ContentDispositionParser

public ContentDispositionParser()

Constructor for the ContentDispositionParser object. This is used to create a parser that can parse a disposition header which is typically sent as part of a multipart upload. It can be used to determine the type of the upload.

ContentDispositionParser

public ContentDispositionParser(String text)

Constructor for the ContentDispositionParser object. This is used to create a parser that can parse a disposition header which is typically sent as part of a multipart upload. It can be used to determine the type of the upload.

Parameters:

text - this is the header value that is to be parsed

Method Detail

getFileName

public String getFileName()

This method is used to acquire the file name of the part. This is used when the part represents a text parameter rather than a file. However, this can also be used with a file part.

Specified by:

getFileName in interface ContentDisposition

Returns:

this returns the file name of the associated part

getName

public String getName()

This method is used to acquire the name of the part. Typically this is used when the part represents a text parameter rather than a file. However, this can also be used with a file part.

Specified by:

getName in interface ContentDisposition

Returns:

this returns the name of the associated part

isFile

public boolean isFile()

This method is used to determine the type of a part. Typically a part is either a text parameter or a file. If this is true then the content represented by the associated part is a file.

Specified by:

isFile in interface ContentDisposition

Returns:

this returns true if the associated part is a file

init

protected void init()

This will initialize the Parser when it is ready to parse a new String. This will reset the parser to a ready state. This method is invoked by the parser before the parse method is invoked, it is used to pack the contents of the header and clear any previous tokens used.

Specified by:

init in class Parser

clear

protected void clear()

This is used to clear all previously collected tokens. This allows the parser to be reused when there are multiple source strings to be parsed. Clearing of the tokens is performed when the parser is initialized.

parse

protected void parse()

This is the method that should be implemented to read the buffer. This method will extract the type from the header and the tries to extract the optional parameters if they are in the header. The optional parts are the file name and name.

Specified by:

parse in class Parser
