Method Detail

parse

public abstract ParserResult<T> parse(String input)

named

public Parser<T> named(String name)

map

public <U> Parser<U> map(Function<T,U> transform)

this.map(transform) succeeds if this succeeds and transform is used to convert the result of this

Parameters:

transform - Function to transform the result from T -> U

Returns:

a `Parser` that -- on success -- returns the result after applying transform.

thenR

public <U> Parser<U> thenR(Parser<U> another)

this.thenR(another) succeeds if this succeeds and another succeeds on the input left over by this

Parameters:

another - Another Parser

Returns:

a `Parser` that -- on success -- returns the result of `another`.

thenL

public <U> Parser<T> thenL(Parser<U> another)

this.thenL(another) succeeds if this succeeds and another succeeds on the input left over by this

Parameters:

another - Another Parser

Returns:

a `Parser` that -- on success -- returns the result of `another`.

then

public <U> Parser<Tuple2<T,U>> then(Parser<U> another)

this.thenL(another) succeeds if this succeeds and another succeeds on the input left over by this

Parameters:

another - Another Parser

Returns:

a `Parser` that -- on success -- returns the result of both `this` and `another`

or

public Parser<T> or(Parser<T> another)

this.or(another) succeeds if this succeeds or another succeeds on the given input. another parser is not evaluated if this succeeds.

Parameters:

another - Another Parser

Returns:

a `Parser` that -- on success -- returns the result of either `this` or `another`

debug

public Parser<T> debug()

skip

public Parser<T> skip(int nChars)
