Member Function Documentation

LexerError()

void SEAMSFlexLexer::LexerError ( const char *  msg )

protectedvirtual

LexerInput()

int SEAMSFlexLexer::LexerInput ( char *  buf, int  max_size  )

protectedvirtual

Reimplemented in SEAMS::Scanner.

LexerOutput()

void SEAMSFlexLexer::LexerOutput ( const char *  buf, int  size  )

protectedvirtual

Reimplemented in SEAMS::Scanner.

switch_streams()

void SEAMSFlexLexer::switch_streams ( std::istream *  new_in, std::ostream *  new_out = nullptr  )

overridevirtual

Implements FlexLexer.

yy_create_buffer()

YY_BUFFER_STATE SEAMSFlexLexer::yy_create_buffer ( std::istream *  file, int  size  )

overridevirtual

Allocate and initialize an input buffer state.

Parameters

file	A readable stream.
size	The character buffer size in bytes. When in doubt, use YY_BUF_SIZE.

Returns

the allocated buffer state.

Implements FlexLexer.

yy_delete_buffer()

void SEAMSFlexLexer::yy_delete_buffer ( struct yy_buffer_state *  b )

overridevirtual

Destroy the buffer.

Parameters

b	a buffer created with yy_create_buffer()

Implements FlexLexer.

yy_flush_buffer()

void SEAMSFlexLexer::yy_flush_buffer ( struct yy_buffer_state *  b )

protected

Discard all buffered characters. On the next scan, YY_INPUT will be called.

Parameters

b	the buffer state to be flushed, usually YY_CURRENT_BUFFER.

yy_get_next_buffer()

int SEAMSFlexLexer::yy_get_next_buffer ( )

protected

yy_get_previous_state()

protected

yy_switch_to_buffer()

void SEAMSFlexLexer::yy_switch_to_buffer ( struct yy_buffer_state *  new_buffer )

overridevirtual

Switch to a different input buffer.

Parameters

new_buffer

The new input buffer.

Implements FlexLexer.

yy_top_state()

int SEAMSFlexLexer::yy_top_state ( )

protected

yy_try_NUL_trans()

yypop_buffer_state()

void SEAMSFlexLexer::yypop_buffer_state

(

void

)

Removes and deletes the top of the stack, if present. The next element becomes the new top.

yypush_buffer_state()

void SEAMSFlexLexer::yypush_buffer_state

(

struct yy_buffer_state *

new_buffer

)

Pushes the new state onto the stack. The new state becomes the current state. This function will allocate the stack if necessary.

Parameters

yyrestart()

void SEAMSFlexLexer::yyrestart ( std::istream *  input_file )

overridevirtual

Immediately switch to a different input stream.

Parameters

input_file

A readable stream.

Note

This function does not reset the start condition to INITIAL .
