Constructor Detail

StreamParser

public StreamParser(java.lang.String string,
                    java.lang.String charset)

Creates a new instance of StreamParser which will read the contents of the supplied String

StreamParser

public StreamParser(java.io.InputStream stream,
                    java.lang.String charset)

Method Detail

getCharset

public java.lang.String getCharset()

Creates a new instance of StreamParser which will read the contents of the supplied Reader

setParseRule

public void setParseRule(int type,
                         int length)

Sets the parse rule and the length of the element to be parsed. This will be called only for Fixed Length files

Parameters:

type - should be StreamParser.FIXED_LENGTH

length - the number of characters to be read

setParseRule

public void setParseRule(int type,
                         char sep)

sets the parse rule and separator character of the element to be parsed. This is only called for simple Separated files

Parameters:

type - should be StreamParser.SEPARATED_STRING

sep - the separator character

setParseRule

public void setParseRule(int type,
                         char sep,
                         char esc)

sets the parse rule, separator character and escape / quote character for the element to be parsed.
e.g.
setParseRule(ESCAPED_STRING, ',', '?') would enable parsing of [[to be?, or not to be,]]
setParseRule(QUOTED_STRING, ',', '"') would enable parsing of [["to be, or not to be",]]

Parameters:

type - can be either StreamParser.ESCAPED_STRING or StreamParser.QUOTED_STRING

sep - the separator character of this element

esc - either the escape char of this element or the quote char

readElement

public void readElement()
                 throws java.lang.Exception

reads the next elemement from the source of this StreamParser according to the specified parse rule

Throws:

java.lang.Exception

getContent

public java.lang.String getContent()

returns the data extracted by the last readElement() call

rewindElement

public void rewindElement(java.lang.String string)
                   throws java.io.IOException

Puts the supplied String back on the source for re-reading

Throws:

java.io.IOException
