Header: Poco/HexBinaryEncoder.h
Description
This streambuf encodes all data written to it in hexBinary encoding and forwards it to a connected ostream. In hexBinary encoding, each binary octet is encoded as a character tuple, consisting of two hexadecimal digits ([0-9a-fA-F]) representing the octet code. See also: XML Schema Part 2: Datatypes (http://www.w3.org/TR/xmlschema-2/), section 3.2.15.
Note: The characters are directly written to the ostream's streambuf, thus bypassing the ostream. The ostream's state is therefore not updated to match the buffer's state.

Member Functions
close
int close();
Closes the stream buffer.
getLineLength
int getLineLength() const;
Returns the currently set line length.
setLineLength
void setLineLength(
int lineLength
);
Specify the line length.
After the given number of characters have been written, a newline character will be written.
Specify 0 for an unlimited line length.
setUppercase
void setUppercase(
bool flag = true
);
Specify whether hex digits a-f are written in upper or lower case.
