IO helpers (experimental, changes expected).

bounded-input-stream clj

(bounded-input-stream input
                      size
                      &
                      {:keys [propagate-close] :or {propagate-close true}})

Creates an instance of InputStream bounded to a specified size.

buffered-input-stream clj

(buffered-input-stream input
                       &
                       {:keys [buffer-size]
                        :or {buffer-size default-buffer-size}})

buffered-output-stream clj

(buffered-output-stream output
                        &
                        {:keys [buffer-size]
                         :or {buffer-size default-buffer-size}})

bytes-input-stream clj

(bytes-input-stream data & {:keys [offset size]})

Creates an instance of unsyncronized ByteArrayInputStream instance holding the provided data.

bytes-output-stream clj

(bytes-output-stream & {:keys [size]})

Creates an instance of ByteArrayOutputStream.

close! clj

(close! stream)

Close any AutoCloseable resource.

coercible? clj

(coercible? o)

Check if the provided object can be coercible to input stream or output stream. In other workds: checks if it satisfies the jio/IOFactory protocol.

copy! clj

(copy! src
       dst
       &
       {:keys [offset size buffer-size]
        :or {offset 0 size -1 buffer-size default-buffer-size}})

Efficiently copy data from src (should be instance of InputStream) to the dst (which should be instance of OutputStream).

You can specify the size for delimit how much bytes should be written to the dst.

data-input-stream clj

(data-input-stream input)

data-input-stream? clj

(data-input-stream? s)

Check if provided object is an instance of DataInputStream.

data-output-stream clj

(data-output-stream output)

data-output-stream? clj

(data-output-stream? s)

Check if provided object is an instance of DataOutputStream.

default-buffer-size clj

flush! clj

(flush! stream)

Flush the OutputStream

input-stream clj

(input-stream x & {:as opts})

Attempts to coerce its argument into an open java.io.InputStream. Default implementations always return a java.io.BufferedInputStream.

Convenciency API, it forwards directly to the clojure.java.io/make-input-stream.

input-stream? clj

(input-stream? s)

Check if provided object is an instance of InputStream.

output-stream clj

(output-stream x & {:as opts})

Attempts to coerce its argument into an open java.io.InputStream. Default implementations always return a java.io.BufferedInputStream.

Convenciency API, it forwards directly to the clojure.java.io/make-output-stream.

output-stream? clj

(output-stream? s)

Check if provided object is an instance of OutputStream.

read-as-bytes clj

(read-as-bytes input & {:keys [size offset close] :or {close false} :as opts})

Read all data or specified size input and return a byte array.

reader clj

(reader x & {:as opts})

Attempts to coerce its argument into an open java.io.Reader. Default implementations always return a java.io.BufferedReader.

Convenciency API, it forwards directly to the clojure.java.io/make-reader.

resource clj

(resource x)

(resource x loader)

Returns the URL for a named resource. Use the context class loader if no loader is specified. Convenciency API, it forwards directly to the clojure.java.io/resource.

write! clj

(write! src dst & {:keys [size offset close] :or {close false} :as opts})

Writes content from src to the dst.

If dst in an OutputStream it will be closed when copy is finished, you can pass :close? option with false for avoid this behavior.

If size is provided, no more than that bytes will be written to the dst.

write-to-file! clj deprecated

(write-to-file! src dst & {:as opts})

writer clj

(writer x & {:as opts})

Attempts to coerce its argument into an open java.io.Writer. Default implementations always return a java.io.BufferedWriter.

Convenciency API, it forwards directly to the clojure.java.io/make-writer.
