Method Detail

from

public static rx.Observable<byte[]> from(java.io.InputStream i)

Reads from the bytes from a source InputStream and outputs Observable of byte[]s

Parameters:

i - Source InputStream

Returns:

from

public static rx.Observable<byte[]> from(java.io.InputStream i,
                                         int size)

Reads from the bytes from a source InputStream and outputs Observable of byte[]s

Parameters:

i - Source InputStream

size - internal buffer size

Returns:

from

public static rx.Observable<java.lang.String> from(java.io.Reader i)

Reads from the characters from a source Reader and outputs Observable of Strings

Parameters:

i - Source Reader

Returns:

from

public static rx.Observable<java.lang.String> from(java.io.Reader i,
                                                   int size)

Reads from the characters from a source Reader and outputs Observable of Strings

Parameters:

i - Source Reader

size - internal buffer size

Returns:

decode

public static rx.Observable<java.lang.String> decode(rx.Observable<byte[]> src,
                                                     java.lang.String charsetName)

Decodes a stream the multibyte chunks into a stream of strings that works on infinite streams and where handles when a multibyte character spans two chunks.

Parameters:

src -

charsetName -

Returns:

decode

public static rx.Observable<java.lang.String> decode(rx.Observable<byte[]> src,
                                                     java.nio.charset.Charset charset)

Decodes a stream the multibyte chunks into a stream of strings that works on infinite streams and where handles when a multibyte character spans two chunks.

Parameters:

src -

charset -

Returns:

decode

public static rx.Observable<java.lang.String> decode(rx.Observable<byte[]> src,
                                                     java.nio.charset.CharsetDecoder charsetDecoder)

Decodes a stream the multibyte chunks into a stream of strings that works on infinite streams and where it handles when a multibyte character spans two chunks. This method allows for more control over how malformed and unmappable characters are handled.

Parameters:

src -

charsetDecoder -

Returns:

encode

public static rx.Observable<byte[]> encode(rx.Observable<java.lang.String> src,
                                           java.lang.String charsetName)

Encodes a possible infinite stream of strings into a Observable of byte arrays.

Parameters:

src -

charsetName -

Returns:

encode

public static rx.Observable<byte[]> encode(rx.Observable<java.lang.String> src,
                                           java.nio.charset.Charset charset)

Encodes a possible infinite stream of strings into a Observable of byte arrays.

Parameters:

src -

charset -

Returns:

encode

public static rx.Observable<byte[]> encode(rx.Observable<java.lang.String> src,
                                           java.nio.charset.CharsetEncoder charsetEncoder)

Encodes a possible infinite stream of strings into a Observable of byte arrays. This method allows for more control over how malformed and unmappable characters are handled.

Parameters:

src -

charsetEncoder -

Returns:

stringConcat

public static rx.Observable<java.lang.String> stringConcat(rx.Observable<java.lang.String> src)

Gather up all of the strings in to one string to be able to use it as one message. Don't use this on infinite streams.

Parameters:

src -

Returns:

split

public static rx.Observable<java.lang.String> split(rx.Observable<java.lang.String> src,
                                                    java.lang.String regex)

Rechunks the strings based on a regex pattern and works on infinite stream.

 split(["boo:an", "d:foo"], ":") --> ["boo", "and", "foo"]
 split(["boo:an", "d:foo"], "o") --> ["b", "", ":and:f", "", ""]
 

See Pattern

Parameters:

src -

regex -

Returns:

join

public static <T> rx.Observable<java.lang.String> join(rx.Observable<T> source,
                                                       java.lang.CharSequence separator)

Concatenates the sequence of values by adding a separator between them and emitting the result once the source completes.

The conversion from the value type to String is performed via String.valueOf(java.lang.Object) calls.

For example:

 Observable<Object> source = Observable.from("a", 1, "c");
 Observable<String> result = join(source, ", ");
 

will yield a single element equal to "a, 1, c".

Parameters:

source - the source sequence of CharSequence values

separator - the separator to a

Returns:

an Observable which emits a single String value having the concatenated values of the source observable with the separator between elements

byLine

public static rx.Observable<StringObservable.Line> byLine(rx.Observable<java.lang.String> source)

Splits the Observable of Strings by lines and numbers them (zero based index)

Parameters:

source -

Returns:
