Method Details

findNonWhitespace

static int findNonWhitespace(java.lang.String sb,
 int offset)

Find the first non whitespace

Returns:

the rank of the first non whitespace

findEndOfString

static int findEndOfString(java.lang.String sb)

Find the end of String

Returns:

the rank of the end of string

findLineBreak

static int findLineBreak(ByteBuf buffer,
 int index)

Try to find first LF or CRLF as Line Breaking

Parameters:

buffer - the buffer to search in

index - the index to start from in the buffer

Returns:

a relative position from index > 0 if LF or CRLF is found or invalid input: '<' 0 if not found

findLastLineBreak

static int findLastLineBreak(ByteBuf buffer,
 int index)

Try to find last LF or CRLF as Line Breaking

Parameters:

buffer - the buffer to search in

index - the index to start from in the buffer

Returns:

a relative position from index > 0 if LF or CRLF is found or invalid input: '<' 0 if not found

findDelimiter

static int findDelimiter(ByteBuf buffer,
 int index,
 byte[] delimiter,
 boolean precededByLineBreak)

Try to find the delimiter, with LF or CRLF in front of it (added as delimiters) if needed

Parameters:

buffer - the buffer to search in

index - the index to start from in the buffer

delimiter - the delimiter as byte array

precededByLineBreak - true if it must be preceded by LF or CRLF, else false

Returns:

a relative position from index > 0 if delimiter found designing the start of it (including LF or CRLF is asked) or a number invalid input: '<' 0 if delimiter is not found

Throws:

java.lang.IndexOutOfBoundsException - if offset + delimiter.length is greater than buffer.capacity
