InputFilter

Base class for input stream filtering. The provided source stream should generally never be null, though some filters have a need to set this lazily.

class InputFilter : InputStream {

InputStream source;

this(InputStream source);

IConduit conduit [@property getter];

size_t read(void[] dst);

void[] load(size_t max);

IOStream flush();

long seek(long offset, Anchor anchor);

InputStream input [@property getter];

void close();

}

Constructors

this this(InputStream source): Attach to the provided stream. The provided source stream should generally never be null, though some filters have a need to set this lazily.

Members

Functions

close void close(): Close the input.
flush IOStream flush(): Clear any buffered content.
load void[] load(size_t max): Load the bits from a stream, and return them all in an array. The dst array can be provided as an option, which will be expanded as necessary to consume the input.
read size_t read(void[] dst): Read from conduit into a target array. The provided dst will be populated with content from the conduit.
seek long seek(long offset, Anchor anchor): Seek on this stream. Target conduits that don't support seeking will throw an IOException.

Properties

conduit IConduit conduit [@property getter]: Return the hosting conduit.
input InputStream input [@property getter]: Return the upstream host of this filter.

Variables

source InputStream source;: Undocumented in source.
