Member Function Documentation

appendCharacterReference()

void log4cxx::helpers::Transform::appendCharacterReference ( LogString & buf, unsigned int ch )

static

Add ch to buf as an XML character reference.

Parameters

buf	output stream holding the XML data to this point.
ch	the value to encode as a XML character reference

appendEscapingCDATA()

void log4cxx::helpers::Transform::appendEscapingCDATA ( LogString & buf, const LogString & input )

static

Add input to buf while ensuring embedded CDEnd strings (]]>) are handled properly within the message.

The initial CDStart (<![CDATA[) and terminating CDEnd (]]>) of the CDATA section must be added by the calling method. Any NUL character in input is not copied to buf. A character reference is used in place of a character whose value is not permitted by the XML 1.0 specification.

Parameters

buf	Transformed input text is added to this.
input	The text to be appended to buf

appendEscapingTags()

void log4cxx::helpers::Transform::appendEscapingTags ( LogString & buf, const LogString & input )

static

Add input, which may contain HTML tags (ie, <b>, <table>, etc) to buf while replacing any '<' and '>' characters with respective predefined entity references.

Any NUL character in input is not copied to buf. A character reference is used in place of a character whose value is not permitted by the XML 1.0 specification.

Parameters

buf	output stream where to write the modified string.
input	The text to be converted.

appendLegalCharacters()

void log4cxx::helpers::Transform::appendLegalCharacters ( LogString & buf, const LogString & input )

static

Append a transformation of input onto buf.

Only the valid XML 1.0 specification characters (#x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]) are copied to buf. Any special character (<, >, & and ") is replaced with an entity reference.

Parameters

buf	Transformed input text is added to this.
input	The text to be transformed.
