◆ expandCapacity()

void LINE_READER::expandCapacity ( unsigned  aNewsize)
protectedinherited

Will expand the capacity of line up to maxLineLength but not greater, so be careful about making assumptions of capacity after calling this.

Definition at line 165 of file richio.cpp.

References LINE_READER::m_capacity, LINE_READER::m_length, LINE_READER::m_line, and LINE_READER::m_maxLineLength.

Referenced by FILE_LINE_READER::ReadLine(), STRING_LINE_READER::ReadLine(), and ReadLine().

◆ GetSource()

virtual const wxString & LINE_READER::GetSource ( ) const

◆ operator char *()

LINE_READER::operator char * ( ) const
inlineinherited

A casting operator that returns a char* pointer to the start of the line buffer.

Definition at line 137 of file richio.h.

◆ ReadLine()

char * INPUTSTREAM_LINE_READER::ReadLine ( )
overridevirtual

Read a line of text into the buffer and increments the line number counter.

If the line is larger than the maximum length passed to the constructor, then an exception is thrown. The line is nul terminated.

Returns
The beginning of the read line, or NULL if EOF.
Exceptions
IO_ERRORwhen a line is too long.

Implements LINE_READER.
