Method Detail

setMinLine

public void setMinLine(int minLine)

Sets the number of the first line in the input document.

If this method is not invoked, the default value is DEFAULT_MIN_LINE (1).

To avoid inconsistencies, this method should only be invoked before the first token is produced.

Parameters:

minLine - the number of the first line in the input document

setMinColumn

public void setMinColumn(int minColumn)

Sets the number of the first column of each line in the input document.

If this method is not invoked, the default value is DEFAULT_MIN_COLUMN (1).

To avoid inconsistencies, this method should only be invoked before the first token is produced.

Parameters:

minColumn - the number of the first column of each line in the input document

get

public LLJavaLexer3.Token<D> get()

Specified by:

get in interface java.util.function.Supplier<LLJavaLexer3.Token<D>>

stream

public java.util.stream.Stream<LLJavaLexer3.Token<D>> stream()

Returns a sequential token stream with this lexer as its source.

Returns:

a sequential stream over the tokens produces by this lexer.

discard

public java.util.function.Supplier<LLJavaLexer3.Token<D>> discard(LLJavaLexer3.TokenType first,
                                                                  LLJavaLexer3.TokenType... rest)

Returns a functional object that supplies the tokens of this lexer, except for the given types.

Parameters:

first - a token type to discard

rest - an array of more token types to discard

Returns:

a functional object that supplies the tokens of this lexer, except for those of the given types.

discard

public java.util.function.Supplier<LLJavaLexer3.Token<D>> discard(java.util.Set<LLJavaLexer3.TokenType> types)

Returns a functional object that supplies the tokens of this lexer, except for the given types.

Parameters:

types - a set of token types to discard

Returns:

a functional object that supplies the tokens of this lexer, except for those of the given types.
